Uhh #5 the question was divided by 2 and in the answer they changed it to divided by 1/2. 50% divided by 2 is definitely 25%. It would be multiplied by the reciprocal (1/2) not divided by it.
Puzzle 9: 1 , 11 , 21 , 1211 , 111221 , 312211 what is the next number? This puzzle is solved by my brilliant friend Dibyendu patra. According to his logic 1 is called ' one 1 ' that means - 11 11 is called ' two 1 ' that means - 21 21 is called ' one 2 one 1' that means - 1211 1211 is called ' one 1 one 2 two 1' that means - 111221 111221 is called ' three 1 two 2 one 1 ' that means - 312211 312211 is called ' one 3 one 1 two 2 two 1' that means - 13112221 13112221 is the right answer.
For the last question here is my explanation to the answer: The first term is "1", which is read as "one 1". The second term is "11", which is read as "two 1s". The third term is "21", which is read as "one 2 and one 1". The fourth term is "1211", which is read as "one 1, one 2, and two 1s". The fifth term is "111221", which is read as "one 1, one 1, two 2s, and one 1". The sixth term is "312211", which is read as "three 1s, two 2s, and one 1". The pattern continues by describing the previous term in terms of how many of each digit it contains. For example, the seventh term would be "13112221", which is read as "one 3, one 1, two 3s, three 2s, and one 1". Therefore, the seventh term in the sequence is "13112221"...
The question What is half of 2 + 2 is ill formed and ambiguous. PEMDAS / BODMAS applies to math equations, but the rules and conventions of the English language also apply to word problems. People are not wrong to interpret this as 1/2 * (2 + 2). If you meant 1/2 * 2 + 2, then you should have said what is half of two, plus two using rules of English to hint at the precedence intended.
I agree totally. Because Ik 50% is equal to 1/2 but idk where he got the other half from when the question clearly said 2. In math when you divide fractions your supposed to change the division sign to multiplication and change the fraction to the left of the equation to its recipricol. The presentation did Change 2 to 1/2 but didn’t change the division sign. Which leads to an incorrect answer. The answer is supposed to be 0.25 or 1/4. Ik its a lot lol, please correct me if I’m wrong.
Hey I think that why they said 50% divided by 2 is 1 because the speaker meant 50% divided by 2 variables itself (50%). Meaning 50% divided by 50%. But still 50% divided by 2 is still 25% only if not mentioned what it meant
Everyone did the last one incorrect. If the sequence is correct, the last number needs to be infinity. The question asks the last number not the next one.
Does that mean the answer is "Yes, I can"? (you said it is infinity and the question started with "Can you") Also it said number and I'm not sure if infinity is a number.
Are you familiar with sequences? There is no sum sign or even a mention of infinity, so you can assume the sequence is 7 numbers long. You should really be criticising how it's not even a math related question and is just a cheap trick to get more viewers
First half of 50 is 25 Second anything that has no parentheses has to be done step by step from left to right Third anything times 0 is 0 plus 1 is 1 the answer is 1 because there are no parentheses
@@savannahbanana1124 No, it's not left to right. You have to use the order of operations. Brackets, then exponents, then multiplication or division (whichever comes first), and then addition or subtraction (whichever comes first). So it would be 1 + 0 + 1 which equals 2. Secondly, if you have four objects, 50% of that is two objects and 2 divided by 2 is 1, so technically you're right because 1 is 25% of 4. But if you look at it mathematically instead of materialistically, 50% is equal to one half. One half divided by 2 is the same as 1 times 2 divided by 2. That equals 1. The video explained it wrong, you're right, but your answer is also technically wrong.
Why would you ask "What is 50% divided by 2?" and then do 50% divided by a half instead to get your answer? Yes 50% divided by a half is one because dividing by a half is the same as multiplying by 2 and 100%=1, but you didn't say "divided by a half" you explicitly said "divided by two". So why are we dividing by a half instead? Did the team of writers even proof read their own videos? Very unprofessional.
also its in fractions half of 2 is 1 so you use 2 and 1 then add them also what between 2 and 4 its 3 so it will be 3 and 3 its like the half point between those two numbers
5 is wrong too. Half of 50% are 25%! Even if it is right that 1/2 / 1/2 one is; divided by 2 is multiplied by 1/2!!!!!!!!!!!! You have 12 apples, you share half of them with your friend, and a friend of him shows off, your friend shares his 50% with his friend so they have a even number: 3! Three is the 1/4 of 12!
He put 50% as 1/2 but thats assuming he was talking about 50% of 1, which he never specified. 50% can be anything if you dont know what its of. For example, if it was 50% of 100, it would be 50 divided by 2 and you would get 25 instead of 1. So as far as Im concerned he did this incorrectly
Number 3 is utterly misleading. The way the question is phrased, there is nothing separating the first 2 from the other 2. When you don't write the equation in mathematical expression is leaves room for interruption. (2/2)+2=3 but (2+2)/2=2. The the fact that 2+2 is the only part of the question written numerically implies that the expression is in parenthesis or otherwise grouped. This is not a riddle; it is a misleading question. -Sincerely IB Pre-Calculus Student and HL Math Student
And another thing, on question 5 diving by 2 is the same thing as multiplying by 1/2 NOT dividing by 1/2. That makes the answer to the question utterly wrong.
Don't forget, same with 4. He didn't put any commas or other punctuation, so it actually says to divide 40 by 15.5. Clearly, this will result in a messy rational number so people automatically go for the other way, but still, 40/15.5 is correct
Division comes before addition in the order of operations so the 2/2 automatically comes first unless specifically stated that the addition comes before.
GM puppydog it is not. It’s asked to be divided by 2 not 1/2. They just mix up the factor from one picture to the other look at the video again. First he says 50% divided by 2 and on the next picture it says 50% divided by 1/2 they mixed it up therefore 25% is correct and not 1. The equation would’ve been right if it had said 50%*(1/2)
#7 is also wrong, whilst yes, 20=XX and 1=I and 19=XIX, you can’t take away the I from XIX like that, for example, if you were to take away 1 from 3214 you wouldn’t get 324, that’s what he did here, just in another mathematical language Another example similar is, 1 = -1 1 = sqrt(1) = sqrt(-1 x -1) = sqrt(-1) x sqrt(-1) = -1 (You can write sqrt(N x M) as sqrt(N) x sqrt(M)) The thing that is incorrect about 1 = -1 is that sqrt(N x M) = sqrt(N) x sqrt(M) only works when N and M are both positive so sqrt(-1 x -1) does equal 1 because -1 x -1 = 1, sqrt of 1 is 1 (1 x 1 = 1) but you can’t write sqrt(-1 x -1) as sqrt(-1) x sqrt(-1)
Number 5:Let's do it with an example. Okay,question is "what is 50% divided by 2"? I've an apple in my hand,only one apple. Apple's 50%=half of the apple. That means half of the apple divided by 2=simple,it's a quarter. Ok another example with 2 apples. I've two apples in my hand. It's 50%=1 apple. 1 apple divided by 2 equals "half apple" So it's clear.we took two apples ended with a half of apple,means 25%. Like if you get me.
jeffrin n Number 5 is right The answer is 1. 2= 2/1 50% = 1/2 1. 2 _. _ 2. 1 Remember the process would be multiplying across getting 2/2 equaling 1. E/ i multiply across ( numerator × numerator [ 1×2] and denominator × denominator [ 2×1]) Otherwise there is the extra step of changing signs. To change divide to multiply you simply flip the fraction. So 1/2 ÷ 2/1 is the same as 1/2 × 1/2. 1/2 × 1/2 = 1.
OBJECTION!!! On number 5 you asked what is 50% divided by 2 but your answer was to the question what is 50% divided by half. The right calculation would be 1/2:2=1/4 or 25%
Can't believe you could not answer the last riddle! Here is the answer: 1 = one 1 = 11 (the next sequence) 11 = Two 1's = 21 (the next sequence) 21 = One 2 and One 1 = 1211 (the next sequence) 1211 = One 1, One 2, and 2 1's = 111221 (the next sequence) 111221 = Three 1's, Two 2's, and One 1 = 312211 (the next sequence) 312211 = One 3, One 1, Two 2's, and Two 1's = 13112221 (the final sequence) SO, the answer is 13112221
I agree. I suspect a mistake in the question rather than the answer. Dividing by 2 is not the same as dividing by a half - it's the same as multiplying by a half.
I am explaining/debunking all of these. *#1* The answer is, in fact, 0. 1 x 2 x 3 x 4 x 5 x 6 x 7 x 8 x 9 x *0* = *0*. Anything multiplied by zero is zero. They were right about that. *#2* This one is 12, like they said. We use PEMDAS or BEMDAS to calculate. 3 + *3 x 3* - 3 + 3 *3 + 9* - 3 + 3 *12 - 3 + 3* *12* PEMDAS or BEMDAS shows that multiplication comes before addition and subtraction from left to right. *#3* This one was actually correct, contrary to what people think. The answer is 3, but it was phrased weirdly. Once again, PEMDAS or BEMDAS helps us solve. *What is half of 2 + 2?* 2 + *2 / 2* 2 + 1 = 3 However, the problem should have been phrased as “What is the sum of half of 2 and 2?” to avoid confusion. *#4* Yep. This is also correct. The answer is 95. Dividing by a fraction is basically multiplying by the reciprocal (which is the denominator and the numerator switched). PEMDAS or BEMDAS also helps us in this problem. *What is 40 divided by 1/2 plus 15* *40 / 1/2* + 15 *40 / 1/2 = 40 x 2/1* *80 + 15* 95 These past questions were correct, but these next questions are either super vague, or just plain wrong. *#5* I believe this one is incorrect. The answer is 1/4 or .25. *What is 50% divided by 2?* *50% = .5 = 1/2* *1/2 / 2* *1/4* The mistake they made was that they were dividing by 1/2, instead of 2. This leads to a completely different answer. *#6* Another correct answer. However, they do not give you enough time to think. *How can you make 1000 by using 8 exactly 8 times(only using addition)?* 888 + 88 + 8 + 8 + 8 = 1000 Not really an explanation for this one. It is kinda straight forward. They just don’t give you enough time. *#7* The people who thought this question didn’t think about how this video is about math and how using Roman numerals goes against it. The answer is actually impossible. You cannot do this. This is their logic: *Can you take 1 from 19 and leave 20?* XIX (19) - I (1) = XX (20) Math is about calculation, not cutting corners by completely flipping logic on its side. Completely incorrect. *#8* Yes, this is correct. The answer is 2 because the first parts of the equation weren’t part of it. However, completely excluding them doesn’t make sense. 1 + 1 + 1 + 1 + 1 1 + 1 + 1 + 1 + 1 *1 + 1 x 0 + 1 = 2* I get they are trying to get the mindset of “How can we fool these people?”, but it is still annoying. *#9* This is the question they told us to go to the comment section. However, using the mindset they have about these questions, I think I got it. The answer is 13112221. Let me explain (using their logic, of course). 1 11 because there is **one** 1, get it? 21 because there are **two** 1s. 1211 because there is **one** 2 and **one** 1. 111221 because there is **one** 1 and **one** 2 and **two** 1. 312211 because there are **three** 1s and **two** 2s and **one** 1. *13112221 would be the answer because there is one three, one one, two twos, and two ones.* Maybe these math riddles, or at least some of them, went over my head. But, when you say “math riddle”, I wouldn’t think Roman numerals.
The last one is a "look and say sequence" The current term is how you read the previous term, dropping any plurals 1 is the first term 11 is how you read the previous term "one one (a single digit 1)" 21 is how you read the previous term "two one (two single digit 1s)" And so on: 1211 is "one two, one one" (reading 21) 111221 is "one one, one two, two one" (reading 1211) 312211 is "three one, two two, one one" (reading 111221) So the missing term is: 13112221 -- "one three, one one, two two, two one" (reading 312211) The next term after that would be: 1113213211 -- "one one, one three, two one, three two, one one" (reading 13112221) And so on...
last riddle: 13112221 1-->one 1 11-->two 1s 21-->one 2, one 1 1211-->one 1, one 2, two 1s 111221-->three 1s, two 2s, one 1 312211-->one 3, one 1, two 2s, two 1s 13112221

@@mattpain4347 its correct and incorrect both bro It depends on your way of reading the Question Like - what is (50% divided by 2) And - (what is 50%) divided by 2
@@mattpain4347 ohh my bad, I realised that you were correct but I solved it like X/2 = 50/100 => X = 1 Hmm, smh the more correct way of solving it is like (1/2)/2 = 1/4 = 25% Edit : pardon my Grammar
For #5 it said “What is 50% divided by 2” but at the end you changed it to 50% divided by 1/2 🙃 The question clearly asked “What’s 50% divided by 2” 50% is the same as 1/2, so 50% divided by 2 is the same as 1/2 divided by 2, and 1/2 divided by 2 is 1/4 Edit: I honestly don’t understand why so many people are having such a hard time figuring out what 50% divided by 2 is, here is a much easier way, just take the percent sign off of 50%, you now have 50 divided by 2 which is 25, and then just add back the percent sign, what do you have now? *25%*
BRIGHT SIDE: "What is half of 2+2? Answer is 1. Me: Oh well, he forgot the parenthesis/groupings/brackets Also Me: 1/2 of (2 + 2) =1/2 of 4 =Common Sense
UMMMM... first, all questions that are mathematically/logically correct are 1,2,and 4. Second, did you read the title of the video??? It says '9 Math Riddles That'll Stump Even Your Smartest Friends ', not '9 Mathematically Correct Questions That'll Stump No one'.
About the question 2 just follow the rule of P,E,M D,A,S /P 1/E 2/M 3/D 4/A 5/S 6/so multiply first because it was first/if theres P ( ) do the number inside it first and in the question ok so the answer was 12 even me myself was wrong i said 18😅
As others pointed out, #5 is incorrect. I kept shaking my head saying, "No, you said divide by 2, not divide by 1/2," and scrolled down to the comments to see if anyone else saw the same.
Lokana you are wrong because when you divide a whole number by a fraction you basically multiply the whole number by the denominator of the fraction which gives you 2 40•1/2=40*2 May I ask how old you are because you learn this in fifth grade but if you are younger than that I may see how you get confused because you didn’t learn this yet
#8 answer should be 30. If you just listen, then the problem is 1+1+1+1+11+1+1+1+11+1x0+1= ie one+one+one+one+eleven+one+one+one+eleven+one times zero+one= thirty.
The last problem at the end of the video is called "Look-and-Say Sequence" To generate a number of a sequence from a previous number, read off the digits of the previous number, counting the number of digits in groups of the same digit. For example: 1 is read off as "one 1" or 11. 11 is read off as "two 1s" or 21. 21 is read off as "one 2, then one 1" or 1211. And so on. So the next number of the problem is "one 3, one 1, two 2s, two 1s" or 13112221. Fun fact: If you start with 22, it will stay itself forever. 22 is read off as "two 2s" or 22.
Someone with a brain will understand that some of these don’t make sense and some answers are wrong; it’s as if the test sheet doesn’t match the answer sheet. It reminds me of incompetent tutors.
OMG. 50% divided by 2 is NOT 25. It's literally NOT!!!! The question was NOT (50% of 100 divided by 2) which is 25. The question was (50% divided by 2) which is 0.25 or 1/4. The correct answer (Math Professor says so) His clever word play is also wrong.
Audrey Violinist I will put it in other words. Just drop the percentage from 50. Then the question would be 50 divided by 2, which is 25. Then just add the percentage back.
1, 11, 21, 1211, 111221, 312211, 13112221, 1113213211, 31131211131221, and so on, and so on... (one means that there's only one one and there's two ones and there's only one two and one one and that there's one one, one two, and two ones and there's three ones, two twos, and only one one and, you know the rest...)
Last one is simple! But you have to say it out loud. You have to count the numbers. Let me explain: 1 ( say: one 1) 11 ( say: two 1's) 21 ( say: one 2 and one 1) 1211 ( say: one 1, one 2 and two 1's) 111221 ( say: three 1's, two 2's and one 1) 312211 ( say: one 3, one 1, two 2's and two 1's) So the answer is: 13112221 Hope you understand!
you didn't understand. we all agreed about that. but when you divide a half by 2 you get 1/4. he said on the answer 'divided by 1 half' but the question said 2.
You just convert the 50% into decimal by moving two decimal places so u need to convert the number 2 also into decimal so .50/.02=0.01 times 100% to become 1
William Drew it’s kinda hard to tell if you’re arguing, but what dividing by 2 does is multiply the denominator by 2. What he asked was “What’s 50% (or 1/2) divided by 2?” It would then be 1/(2*2)=1/4.
Person with foreign characters for a name, William Drew isn’t wrong about the characteristics of dividing by a fraction, it’s just that he failed to catch the switch in the problem.
04:41 Another mistake in #8. The correct answer is 30. Equation wrapping is a common thing in math. Therefore what's written is actually: 1 + 1 + 1 + 1 + 11 + 1 + 1 + 1 + 11 + 1 * 0 + 1 = 30
Uh, number 5 is actually 25% Let me explain: The question is "50% divided by 2", right? Following that logic, 50% is equal to 0.5 If I were to divide 0.5 by 2, it would be .25, or 25% Now, if I were to divide 50% by 1/2, THAT would equal 1

Fairly certain this video is made to upset people to get comments and views. They absolutely do not care about math or getting people to engage in math.
6:13 Answer is 13112221. The pattern goes like this (btw I'm 12 years old) You start with 1. There is one '1', so you write: '1 1' There are two '1's, so you write: '2 1' There is one '2', and one '1', so you write: '1 2 1 1' There is one '1', one '2', and two '1's, so you write: '1 1 1 2 2 1' There are three '1's, two '2's, and one '1's so you write: '3 1 2 2 1 1' So, since there is one '3', one '1', two '2's, and two '1's, you write '1 3 1 1 2 2 2 1'. It is called the 'Look and say sequence', or the 'look and say sequence triangle'. I learned this when I was 7, forgot about it until today. Thanks BRIGHT SIDE for helping me remember some random stuff, I con't keep track of everything!
#5 is wrong. Let's just say we reduced 50/100 (50%) to 1/2. So after that, you don't divide after you flip the fraction 2/1 to 1/2.... you multiply, and you get 1/4. and if we didnt reduce, we would have gotten 25/100 (25%) or 1/4. It's simple math dude..
how can you justify half of 2 + 2 being 3? its like a packaged deal unless you say something about it. he never said one of the numbers be cut in half then added to the other. he has no sense, and his thinking when it comes to math is flawed so bad it goes back to 3rd or 4th grade.

@@jikjlmvjtcakktbmnjjrsnjsca1770 3:14 They forgot to turn the division sign to a multiplication sign when turning 2 into 1/2 so technically it's 1/4 or 25%
most of the riddles are just plain wrong... for example: XIX-I=XVIII not XX, XX would only be the solution if you aren't talking mathematical and this video claims it's about "MATH riddles" not "riddles that contain numbers"
Actually, numbers are at all costs a part of math, it's just that if you study Roman numerals like I do, Romen numerals represent numbers, but in Romen style, so actually he is correct on the Roman numerals one, be cause if XX represents 20 and XIX represents 19 and I represents 1 then if you take the one out of XIX, 19, you would get XX and as of before I told you XX stands for 20.
I think it is wrong because the right answer is 13112221 if you like to know why read down below 1 was the first number so we have one 1= 11 but know we have two 1 so 21 know we have one 2 and one 1 so 1211 it go on like that= 1=11 11=21 21=1211 1211=111221 111221=312211 312211=13112221 It still could be wrong however I am 99,9% sure it is right 🧐

The pattern continues by describing the previous term in terms of how many of each digit it contains. For example, the seventh term would be "13112221", which is read as "one 3, one 1, two 3s, three 2s, and one 1".
Therefore, the seventh term in the sequence is "13112221"...

@@spiffycat and 50%/2 = 25%
The question What is half of 2 + 2 is ill formed and ambiguous. PEMDAS / BODMAS applies to math equations, but the rules and conventions of the English language also apply to word problems. People are not wrong to interpret this as 1/2 * (2 + 2). If you meant 1/2 * 2 + 2, then you should have said what is half of two, plus two using rules of English to hint at the precedence intended.
Not to mention he reads the question: "what is half of (small pause) 2+2.
The questions are made to trick you
And if you listen to the way he states the problem he compounds the distortion.

50% divided by 2 is 25% or 1/4.
Dividing by 2 is actually multiplying with 1/2 and not dividing by 1/2!!!
Srbin Ponosan yup 50% is 1/2 and 1/2 / 2 is 1/2*1/2 or 1/4

#5 didn't say 50% divided by 1/2...It said 50% divided by 2...Sloppy presentation or cheating: I don't know which...
I agree totally. Because Ik 50% is equal to 1/2 but idk where he got the other half from when the question clearly said 2. In math when you divide fractions your supposed to change the division sign to multiplication and change the fraction to the left of the equation to its recipricol. The presentation did Change 2 to 1/2 but didn’t change the division sign. Which leads to an incorrect answer. The answer is supposed to be 0.25 or 1/4. Ik its a lot lol, please correct me if I’m wrong.
I agree bright side is wrong
I agree too I don’t understand this type of math problem. Probably because the point was to stump people’s minds
Hey I think that why they said 50% divided by 2 is 1 because the speaker meant 50% divided by 2 variables itself (50%). Meaning 50% divided by 50%. But still 50% divided by 2 is still 25% only if not mentioned what it meant
The problem is: the question was different from the answer. He did say: 50% divided by 2, not divided by 1/2.
Everyone did the last one incorrect. If the sequence is correct, the last number needs to be infinity. The question asks the last number not the next one.
Does that mean the answer is "Yes, I can"? (you said it is infinity and the question started with "Can you") Also it said number and I'm not sure if infinity is a number.
Are you familiar with sequences? There is no sum sign or even a mention of infinity, so you can assume the sequence is 7 numbers long. You should really be criticising how it's not even a math related question and is just a cheap trick to get more viewers
Some riddles aren’t worded right or even correct
Did u ply brawl stars
Slydawg16 yeah Q5 especially he sais 50 percent by 2 not by half so it’s 25 percdnt
This is bright side's revenge on the "vicious" math teacher.
First half of 50 is 25 Second anything that has no parentheses has to be done step by step from left to right Third anything times 0 is 0 plus 1 is 1 the answer is 1 because there are no parentheses
@@savannahbanana1124 No, it's not left to right. You have to use the order of operations. Brackets, then exponents, then multiplication or division (whichever comes first), and then addition or subtraction (whichever comes first). So it would be 1 + 0 + 1 which equals 2. Secondly, if you have four objects, 50% of that is two objects and 2 divided by 2 is 1, so technically you're right because 1 is 25% of 4. But if you look at it mathematically instead of materialistically, 50% is equal to one half. One half divided by 2 is the same as 1 times 2 divided by 2. That equals 1. The video explained it wrong, you're right, but your answer is also technically wrong.
Actually, 50 percent divided by 2 (as was the question) is 25 percent. You can even put it into a calculator and check. You just did the math wrong.
huh
50% divided by 2 is the same as 1/2 times 1/2 rather than 1/2 divided by 1/2 like the video says
I thought it was 25%. You can't just say it's 1/2 like in the video... can you?
im agreeing with you mate 1/2*1/2 is 1/4 or 0.25 or 25%, the video says its the same as 1/2 divided by 1/2
I agree with you. He didn't say divided by 1/2, he said divided by 2. He is absolutely wrong on that one. I agree that it is 0.25, or 25%
Why would you ask "What is 50% divided by 2?" and then do 50% divided by a half instead to get your answer? Yes 50% divided by a half is one because dividing by a half is the same as multiplying by 2 and 100%=1, but you didn't say "divided by a half" you explicitly said "divided by two". So why are we dividing by a half instead? Did the team of writers even proof read their own videos? Very unprofessional.
I did 1/2÷2=1/2×1/2=1/4. You are right

i dont literally agree with riddle three cause the answer is 2
explanation:
*HALF* (of 2 + 2)
=2 + 2
=4 divided by 2
=2
The Main Word here is *of*
But it says what is half of 2 +2
Half of 2 is 1 and 1+2 is 3. You just have to think about it.
You have to think outside of the box lol
also its in fractions half of 2 is 1 so you use 2 and 1 then add them also what between 2 and 4 its 3 so it will be 3 and 3 its like the half point between those two numbers
He said half of 2 which is 1+2 and it's three
We first do divided
#5 is wrong
To divide by 2 is not dividing by 1/2, it's multiplying by 1/2.
If 50% is represented by 1/2, then 1/2 ÷ 2 = 1/2 *1/2 = 1/4 , not 1
TheDudeOfDarkness so is number three
That's exactly what I thought. When they said what the answer was, I was like THATS NOT RIGHT 50 DIVIDED BY 2 IS 25 AND THERE IS NO OTHER ANSWER
oh yea
TheDudeOfDarkness same with 1+1+1+1+1+1+1+1+1+1+1+1×0+1 they claim it's 2 but it's 1 cause it would be 12×0 plus 1 which is 1
TheDudeOfDarkness no when an equation is in divide then it goes as multiply(reciprocal) that's why 1/2*1/2=1/2*2=2*2=1
5 is wrong too. Half of 50% are 25%! Even if it is right that 1/2 / 1/2 one is; divided by 2 is multiplied by 1/2!!!!!!!!!!!! You have 12 apples, you share half of them with your friend, and a friend of him shows off, your friend shares his 50% with his friend so they have a even number: 3! Three is the 1/4 of 12!
Indeed!!! Instead of dividing 50% by 2, he divided it by 1/2...
Bright side was right,buds.You want to think outside the box?You better think outside the planet for this one.
Yup, 25%
Yeah i was thinking the same it should be 25%
He put 50% as 1/2 but thats assuming he was talking about 50% of 1, which he never specified. 50% can be anything if you dont know what its of. For example, if it was 50% of 100, it would be 50 divided by 2 and you would get 25 instead of 1. So as far as Im concerned he did this incorrectly
This silly man just wrote 50% divided by 2 and changed the question and gave the answer by 50% divided by half
Exactly
Number 3 is utterly misleading. The way the question is phrased, there is nothing separating the first 2 from the other 2. When you don't write the equation in mathematical expression is leaves room for interruption. (2/2)+2=3 but (2+2)/2=2. The the fact that 2+2 is the only part of the question written numerically implies that the expression is in parenthesis or otherwise grouped. This is not a riddle; it is a misleading question.

And another thing, on question 5 diving by 2 is the same thing as multiplying by 1/2 NOT dividing by 1/2. That makes the answer to the question utterly wrong.
Don't forget, same with 4. He didn't put any commas or other punctuation, so it actually says to divide 40 by 15.5. Clearly, this will result in a messy rational number so people automatically go for the other way, but still, 40/15.5 is correct
Division comes before addition in the order of operations so the 2/2 automatically comes first unless specifically stated that the addition comes before.
Yes, but he verbally implied parentheses, because he didn't insert any commas
Chloe Morton, exactly these answers aren't correct, he needs to go back to school FOR REAL 😳🙄😒....😄🤓🤓🤓
3:05 what you said divided by 2 not divided by 1/2 you literally just changed the question

It implies 2 + 2 then divide.

This guy doesn't know math
50 percent ÷ 2 is like saying 50 ÷ 2 so the answer is 25 percent OR 1/4
that's just SIMPLE MATH
#math
You can even put it into a calculator and it'll come up with 25%
SiddlesProGamer but it's 1/2 not 2 think about that
Guys it is 2
GM puppydog it is not. It’s asked to be divided by 2 not 1/2. They just mix up the factor from one picture to the other look at the video again. First he says 50% divided by 2 and on the next picture it says 50% divided by 1/2 they mixed it up therefore 25% is correct and not 1. The equation would’ve been right if it had said 50%*(1/2)
#7 is also wrong, whilst yes, 20=XX and 1=I and 19=XIX, you can’t take away the I from XIX like that, for example, if you were to take away 1 from 3214 you wouldn’t get 324, that’s what he did here, just in another mathematical language
Another example similar is, 1 = -1
1 = sqrt(1) = sqrt(-1 x -1) = sqrt(-1) x sqrt(-1) = -1 (You can write sqrt(N x M) as sqrt(N) x sqrt(M))
The thing that is incorrect about 1 = -1 is that sqrt(N x M) = sqrt(N) x sqrt(M) only works when N and M are both positive so sqrt(-1 x -1) does equal 1 because -1 x -1 = 1, sqrt of 1 is 1 (1 x 1 = 1) but you can’t write sqrt(-1 x -1) as sqrt(-1) x sqrt(-1)
Number 5:Let's do it with an example.
Okay,question is "what is 50% divided by 2"?
I've an apple in my hand,only one apple.
Apple's 50%=half of the apple.
That means half of the apple divided by 2=simple,it's a quarter.
Ok another example with 2 apples.
I've two apples in my hand.
It's 50%=1 apple.
1 apple divided by 2 equals "half apple"
So it's clear.we took two apples ended with a half of apple,means 25%.
Like if you get me.
jeffrin n
Number 5 is right
The answer is 1.
2= 2/1
50% = 1/2
1. 2
_. _
2. 1
Remember the process would be multiplying across getting 2/2 equaling 1.
E/ i multiply across ( numerator × numerator [ 1×2] and denominator × denominator [ 2×1])
Otherwise there is the extra step of changing signs. To change divide to multiply you simply flip the fraction.
So 1/2 ÷ 2/1 is the same as 1/2 × 1/2.
1/2 × 1/2 = 1.
jeffrin n not how it works tho
Jacob Legault just tell me this honestly,what is 50% × 2 = ?
Well 50% is 0.5. 0.5/2=0.25 right?
Clash Nite i am talking about multiplication,dude!
OBJECTION!!! On number 5 you asked what is 50% divided by 2 but your answer was to the question what is 50% divided by half. The right calculation would be 1/2:2=1/4 or 25%

Can't believe you could not answer the last riddle! Here is the answer:
1 = one 1 = 11 (the next sequence)
11 = Two 1's = 21 (the next sequence)
21 = One 2 and One 1 = 1211 (the next sequence)
1211 = One 1, One 2, and 2 1's = 111221 (the next sequence)
111221 = Three 1's, Two 2's, and One 1 = 312211 (the next sequence)
312211 = One 3, One 1, Two 2's, and Two 1's = 13112221 (the final sequence)
SO, the answer is 13112221

SkyDuster 1 is half of 2 = 1/2 😁
Sky Duster is right. The answer is 1/4. 50% split into groups of 2 gives 2 groups of 25%
I agree. I suspect a mistake in the question rather than the answer. Dividing by 2 is not the same as dividing by a half - it's the same as multiplying by a half.
True
SkyDuster keep change flip
I am explaining/debunking all of these.
*#1*
The answer is, in fact, 0.
1 x 2 x 3 x 4 x 5 x 6 x 7 x 8 x 9 x *0* = *0*.
Anything multiplied by zero is zero. They were right about that.
*#2*
This one is 12, like they said. We use PEMDAS or BEMDAS to calculate.
3 + *3 x 3* - 3 + 3
*3 + 9* - 3 + 3
*12 - 3 + 3*
*12*
PEMDAS or BEMDAS shows that multiplication comes before addition and subtraction from left to right.
*#3*
This one was actually correct, contrary to what people think. The answer is 3, but it was phrased weirdly.
Once again, PEMDAS or BEMDAS helps us solve.
*What is half of 2 + 2?*
2 + *2 / 2*
2 + 1 = 3
However, the problem should have been phrased as “What is the sum of half of 2 and 2?” to avoid confusion.
*#4*
Yep. This is also correct. The answer is 95.
Dividing by a fraction is basically multiplying by the reciprocal (which is the denominator and the numerator switched).
PEMDAS or BEMDAS also helps us in this problem.
*What is 40 divided by 1/2 plus 15*
*40 / 1/2* + 15
*40 / 1/2 = 40 x 2/1*
*80 + 15*
95
These past questions were correct, but these next questions are either super vague, or just plain wrong.
*#5*
I believe this one is incorrect. The answer is 1/4 or .25.
*What is 50% divided by 2?*
*50% = .5 = 1/2*
*1/2 / 2*
*1/4*
The mistake they made was that they were dividing by 1/2, instead of 2. This leads to a completely different answer.
*#6*
Another correct answer. However, they do not give you enough time to think.
*How can you make 1000 by using 8 exactly 8 times(only using addition)?*
888 + 88 + 8 + 8 + 8 = 1000
Not really an explanation for this one. It is kinda straight forward. They just don’t give you enough time.
*#7*
The people who thought this question didn’t think about how this video is about math and how using Roman numerals goes against it. The answer is actually impossible. You cannot do this.
This is their logic:
*Can you take 1 from 19 and leave 20?*
XIX (19) - I (1) = XX (20)
Math is about calculation, not cutting corners by completely flipping logic on its side. Completely incorrect.
*#8*
Yes, this is correct. The answer is 2 because the first parts of the equation weren’t part of it. However, completely excluding them doesn’t make sense.
1 + 1 + 1 + 1 + 1
1 + 1 + 1 + 1 + 1
*1 + 1 x 0 + 1 = 2*
I get they are trying to get the mindset of “How can we fool these people?”, but it is still annoying.
*#9*
This is the question they told us to go to the comment section. However, using the mindset they have about these questions, I think I got it. The answer is 13112221. Let me explain (using their logic, of course).
1
11 because there is **one** 1, get it?
21 because there are **two** 1s.
1211 because there is **one** 2 and **one** 1.
111221 because there is **one** 1 and **one** 2 and **two** 1.
312211 because there are **three** 1s and **two** 2s and **one** 1.
*13112221 would be the answer because there is one three, one one, two twos, and two ones.*
Maybe these math riddles, or at least some of them, went over my head. But, when you say “math riddle”, I wouldn’t think Roman numerals.
Skander Souiai That is right as well. I use PEMDAS because that was what I was taught. There are multiple abbreviations.

Wow, everybody is complaining about the question 50%/0.5 :)
The last one is a "look and say sequence"
The current term is how you read the previous term, dropping any plurals
1 is the first term
11 is how you read the previous term "one one (a single digit 1)"
21 is how you read the previous term "two one (two single digit 1s)"
And so on:
1211 is "one two, one one" (reading 21)
111221 is "one one, one two, two one" (reading 1211)
312211 is "three one, two two, one one" (reading 111221)
So the missing term is:
13112221 -- "one three, one one, two two, two one" (reading 312211)
The next term after that would be:
1113213211 -- "one one, one three, two one, three two, one one" (reading 13112221)
And so on...

For #5 it said “What is 50% divided by 2” but at the end you changed it to 50% divided by 1/2 🙃
The question clearly asked “What’s 50% divided by 2” 50% is the same as 1/2, so 50% divided by 2 is the same as 1/2 divided by 2, and 1/2 divided by 2 is 1/4
Edit: I honestly don’t understand why so many people are having such a hard time figuring out what 50% divided by 2 is, here is a much easier way, just take the percent sign off of 50%, you now have 50 divided by 2 which is 25, and then just add back the percent sign, what do you have now? *25%*

50%means 50/100is divided by 2 50/100/2 in there 2 comes reciprocal so 50×2/100=100/100=1☺
@@sangeethasangeetha1953 nope that's not how it works man.. 50% divided by 2 means 1/2 * 50/100 = 50/200 = 1/4 = 0,25 aka 25%
📊 The last one is difficult though.
Number 5 is wrong! They said 50% divided by 2, not 1/2. So it’s actually 25%

Oh
Also half of 2 doesn't need parentheses because it's a multiplication of 1/2 and 2
None of these answers that he gave are correct if you actually do the math except the first one

No prob. :P
Predator X: no, because there are no "=" marks after each line. So we skip first lines and jump straight to:

About the question 2 just follow the rule of P,E,M D,A,S /P 1/E 2/M 3/D 4/A 5/S 6/so multiply first because it was first/if theres P ( ) do the number inside it first and in the question ok so the answer was 12 even me myself was wrong i said 18😅

As others pointed out, #5 is incorrect. I kept shaking my head saying, "No, you said divide by 2, not divide by 1/2," and scrolled down to the comments to see if anyone else saw the same.
Lokana you are wrong because when you divide a whole number by a fraction you basically multiply the whole number by the denominator of the fraction which gives you 2
40•1/2=40*2
May I ask how old you are because you learn this in fifth grade but if you are younger than that I may see how you get confused because you didn’t learn this yet
Finally, someone who gets it
no its correct 1/2 divided by 2 is 1/2/2 who means 2/2=1
Lokana I did, I was so mad about that!
In #7 I answered negative numbers, which is still correct because -19-1 = -20
For #7...
If we write 19 as (20-1) and the we take the 1, we get (20-0) which is equal to 20!

#8 answer should be 30.
If you just listen, then the problem is 1+1+1+1+11+1+1+1+11+1x0+1=
ie one+one+one+one+eleven+one+one+one+eleven+one times zero+one= thirty.
The last problem at the end of the video is called "Look-and-Say Sequence"
To generate a number of a sequence from a previous number, read off the digits of the previous number, counting the number of digits in groups of the same digit.
For example:
1 is read off as "one 1" or 11.
11 is read off as "two 1s" or 21.
21 is read off as "one 2, then one 1" or 1211.
And so on.
So the next number of the problem is "one 3, one 1, two 2s, two 1s" or 13112221.
Fun fact: If you start with 22, it will stay itself forever.
22 is read off as "two 2s" or 22.
I have no clue what you just typed but ok
Umm.... Yeah i understood 😅😅😅
Other fun fact: there can never be a 4 in the sequence…
Thank you for the answer it was really bothering me!!!

Omg. 50% divided by 2 is 25. It’s literally 50 divided by 2. YOU DONT HAVE TO MAKE EVERYTHING SO COMPLICATED. IT’s not right. *_*
OMG. 50% divided by 2 is NOT 25. It's literally NOT!!!!
The question was NOT (50% of 100 divided by 2) which is 25.
The question was (50% divided by 2) which is 0.25 or 1/4. The correct answer (Math Professor says so)
His clever word play is also wrong.
It's not 25, but it is 25%.
jorgensenmj he ment 25% ..
Dan He 25%
Dan He or 1 fourth
#5 is completely wrong..
If 50% = 1/2 then it is 1/2 divided by 2 which is 1/4. 1/4 = 25%
1/2 divided by ____ = double
Idon Tknow 50%=1/2. Then you need to divide by 1/2 which is basically 1/2x2/1 which gives you 2/2 which is equal to 1
Audrey Violinist I will put it in other words.
Just drop the percentage from 50. Then the question would be 50 divided by 2, which is 25. Then just add the percentage back.
Idon Tknow I thought it was 0.25

21
( say: one 2 and one 1)
1211

( say: three 1's, two 2's and one 1)
312211

#5 is wrong. The question says "What is 50% divided by 2" but when he was going through the problem, he said divided by 1/2.
SpiceToTheMax yes I agree
you didn't understand.
we all agreed about that. but when you divide a half by 2 you get 1/4. he said on the answer 'divided by 1 half' but the question said 2.
SpiceToTheMax u right
Yes, I thought that too
yeah thats true
uh 50% = .5 and .5 divided by 2 is .25 there, bub
Exactly
You just convert the 50% into decimal by moving two decimal places so u need to convert the number 2 also into decimal so .50/.02=0.01 times 100% to become 1
Yup our mind is going in right direction my answer is 1/4

Woah, hold up. At 3:15 into the vid, you said that 50% divided by 2 is 1.
0.5/2 does not equal 1!!!!
0.25 is right answer
William Drew it’s kinda hard to tell if you’re arguing, but what dividing by 2 does is multiply the denominator by 2. What he asked was “What’s 50% (or 1/2) divided by 2?” It would then be 1/(2*2)=1/4.
He changed the problem from 1/(2*2) to (1/2)/(1/2). That’s a big problem.
William Drew use a calculator
Person with foreign characters for a name, William Drew isn’t wrong about the characteristics of dividing by a fraction, it’s just that he failed to catch the switch in the problem.
04:41 Another mistake in #8. The correct answer is 30. Equation wrapping is a common thing in math. Therefore what's written is actually:
1 + 1 + 1 + 1 + 11 + 1 + 1 + 1 + 11 + 1 * 0 + 1 = 30
I think the answer to the last question is either 1312211 or 4312211.
But why do you always have a last question with no answer?
Uh, number 5 is actually 25%
Let me explain:
The question is "50% divided by 2", right?
Following that logic, 50% is equal to 0.5
If I were to divide 0.5 by 2, it would be .25, or 25%
Now, if I were to divide 50% by 1/2, THAT would equal 1
EliGD ye is 25
Well it’s basically a trick question
clickbait or he just cant learn maths

13112221 actually read the previous number and put the count of the number, a number appears. For example:
first number is 1
So next number is 1 time 1 is written =11
Now third number is -- read 11 as 2 times 1 is written =21
Now fourth number is -- read 21 it is 1 times 2 and then 1 times 1 =1211
Similarly fifth number is -- 1 time 1 and 1 time 2 and 2 times 1=111221
Similarly 6th number is-- 3 times 1, 2 times 2,1 times 1=312211
SO 7th number is--- 1 times 3, 1 times 1, 2 times 2,2 times 1=13112221

6:13 Answer is 13112221. The pattern goes like this (btw I'm 12 years old)
You start with 1.
There is one '1', so you write: '1 1'
There are two '1's, so you write: '2 1'
There is one '2', and one '1', so you write: '1 2 1 1'
There is one '1', one '2', and two '1's, so you write: '1 1 1 2 2 1'
There are three '1's, two '2's, and one '1's so you write: '3 1 2 2 1 1'
So, since there is one '3', one '1', two '2's, and two '1's, you write '1 3 1 1 2 2 2 1'.
It is called the 'Look and say sequence', or the 'look and say sequence triangle'.

#5 is wrong. Let's just say we reduced 50/100 (50%) to 1/2. So after that, you don't divide after you flip the fraction 2/1 to 1/2.... you multiply, and you get 1/4. and if we didnt reduce, we would have gotten 25/100 (25%) or 1/4. It's simple math dude..

answer on last riddle 13112221
most of the riddles are just plain wrong... for example: XIX-I=XVIII not XX, XX would only be the solution if you aren't talking mathematical and this video claims it's about "MATH riddles" not "riddles that contain numbers"
That's also true.
Actually, numbers are at all costs a part of math, it's just that if you study Roman numerals like I do, Romen numerals represent numbers, but in Romen style, so actually he is correct on the Roman numerals one, be cause if XX represents 20 and XIX represents 19 and I represents 1 then if you take the one out of XIX, 19, you would get XX and as of before I told you XX stands for 20.
