"why" is such an important question!! ... All our teachers literally scared us so much that we always refrained ourselves from asking this question to them.
School is the most useless hopeless and disgraceful thing in this country. It ruined everything . The dreams of the children r taken for granted . School is equivalent to jail . I would burn this jail to ashes.
When our school teacher was teaching this I was the only one in class who asked why and many people laughed cause they thought I was cracking a joke and the teacher said it's just a fact.Then I said that how is this fact true the teacher then told to learn it this way but then I again asked the logic behind it and why so the teacher scolded me saying I was asking unnecessary questions and told me to leave the class and I didn't even bothered browsing about the answer in the web because of this incident.And finally after 3 years (I am in ninth grade now) I got the answer !☺
If you really want to understand why a negative times a negative is a positive, you will need to take a class on analysis I or advanced calculus. Basically, you begin with a set of rules to construct the natural numbers called the Peano axioms. Once you have the natural numbers, you can construct the set of integers (these include negatives) as an ordered pair of natural numbers. While constructing the integers, you with learn that negation is defined to "reverse" the ordered pair of natural numbers. Also you with need to define how to do integer multiplication. From the definition of integer multiplication and negation, the only logical outcome is that a negative times a negative is a positive. This kind of math is known as rigorous math or analysis.
I will note though, that analysis came much later on. Before a negative times a negative equals a positive was just a fact you had to take on faith since you would have inconsistencies if this were not the case. And the whole purpose of math is for it to be consistent.
This come simply from *nature* itself Example: Person A : You don't(-) want to eat? Person B : No(-) Means he want to eat(+) If person B said "yes" then the conclusion would be i don't want to eat(-) Vice-versa answer would be (-) negative so maths comes from our inside only... Hope you got it have a nice remaining day😃!
I wondered why some years ago. I imagined + as someone giving me money and - as me giving them money. It almost worked well but wasn't satisfactory but this great! Thank you
Sir if you are in exam hall and the question is about speed of train, will you book train ticket, give directions to loco driver to maintain the speed of your question? It's for explanation...
But you didnt explain WHY you simply showed me, using your own rules, how to walk across a number line. Is this an actuall rule for numberlines or is it just something you came up with?
klaik30 yeah that whole "the first number determines which way you face" thing seems like a useful way to help you visualise getting the answer, but I also struggled to see how that's the reason as to WHY multiplying two negatives makes a positive.
WHO CARES? We say Something a rule if it works with every no.(here). So maybe it isn't a rule (idk) but he clearly showed that it works in every situation. So now this rule DOES EXISTS.
ThE DaRk KnIghT we care because the title of the video says "Why?" in it, yet he never specifically explains why multiplying two minus numbers makes a plus. He merely gives you a useful method for visualising how to get the answer.
Let's say you owe bank Rs. 100 in account A. That means your balance in account A is -100. Now let's say the bank owes you three times as much amount in another account B. What is your balance in account B? Since the direction of "owing" has changed compared to account A, the multiplier will be -3. Balance in account B is therefore -3 x -100 = 300... The positive sign showing that bank owes you this amount, unlike account A where you owe the bank. Hope this clarifies...
In the example given by Nganba, both accounts have negative balances and since direction of "owing" is same in both accounts, multiplier is 2. In both accounts if you had -100 balance, total balance will be 2x-100 = -200. Negative balance shows you still owe the bank...
Simply get any two numbers and multiply and then the result of that would be either forward times or backward times the last remaining number . as you r doing it in a single dimension only
Simple. you multipky the first two numbers. take the answer and multiply it to the third number. if there's a fourth number, take the answer of the first answer times the third number and multiply it to the fourth number. just do it two at a time to apply the logic and you can keep multiplying up to 10 or 100 or so numbers.
Thank you sir for such wonderful explanation. One day I teach my son who is in 6th grade the multiplication of integers. While teaching I told him that -2 x -4 = +8, he asked “why” it is +ve not -ve. I tried to convince him in many ways but he was not convinced at all. Then I told his maths teacher to explain the concept. As while my childhood I mug up that multiplication of two -ve numbers are +ve only and my mind accepted that till date. But when my son questioned me, I am really anxious to know why it is so. After watching your video, I understand the logic behind this very well and my son too. The words uttered by you that “one more mystery of the universe is solved” are literally true for me. My mind was unaware of this unsolved mystery but I am very thankful to you for solving my untold mystery. Teaching math with such a wonderful trick is really amazing. If mathematics taught by such concepts, nobody hates or fearing of mathematics.
i think the deep reason behind it lies in vector product convention. when we are to multiply two numbers having two extra options of "+" & "-" signs, then we need four directions to describe the multiplication process in two dimensions forming an Area of two faces called front and back. By conventions regarding signs as which sign is prescribed to which direction, the resulting area is resulted in either of two faces having positive or negative sign due to clockwise or anticlockwise multiplication. This video demonstrates the product in one dimension which forces the viewer to imagine the other dimension in mind abstractly.
Mani Kandan in a straight line(y=ax+b)slope and intercept they never have the same unit of measurement. The intercepet has the same unit of measurement of y; the slope has y/x unit of measurement.
If you have 3 baskets per 2 apples, you have 6 of them. If you owe 2 apples to 3 people, you basically have -6 of them. If you owe 2 apples to 3 people that don't exist, you don't have to pay them, so you have 6 of them. Quick maths.
He used Lightsaber as a +ve direction and a Darksaber as a -ve direction in the number line system, and he also mentions the mysteries of the universe, I think Bawa loves the Star Wars series too
in the indian education system... neither are the students interesting in knowing 'why' nor are the teachers interested in explaining 'why'.. and when a student tops , they call themselves 'intelligent'.. this system really sometimes makes me feel ashamed of india
Did u use to ask why??? Here everyone is blaming everyone.. But i think u know that in our education system we students are also a part of it and what we do in colleges??? We bunk class don't do projects still we want to pass every semester....we are the one who don't want to learn and we are the one who can make our system good....
Probably you haven't had much knowledge of Indians. It's too foolish to generalise everything. Not all or every Indians are the way you explained,though many are. The wise man should also look at the history, how many times indians have been looted up amd kept away from development. The process and awareness you're talking about comes with interests and right path which many indians are yet to achieve. Not all Indians are getting the right education. Most of them start their education from govt schools and you know the condition of those schools. Changes are coming. Good governance has come, good things will be seen. Keep patience. And please request you don't generalise. If those "Indians" who call themselves intelligent were foolish to say so, then we would not be so good at space exploration and stuff. We're developing in all the sectors. Give it some time. Don't generalise.

It's same as if asking ,why does a number scale have zero in centre, and negative and positive numbers on either side and that too to infinity and why not just to ten... Lol... Some people can't accept good explanations...
@@rohikmicka2624 hahaha good explanation?? There must be a logic to explanations.. anyways please feel free to believe whatever you want, its your choice !
The operations are representations of logic statements we must read to the end to compute them correctly. -2 × -3 = 6 is read "minus two times minus three equals six." We speak "We don't have time" or "we have no time". But if we say "we don't have no time" we are telling a logical riddle that can be translated in terms of time as "we have time".

You said the first letter let us know which direction I face and the 2nd number tell us in which direction we walk. Now in the case of -2 & +3 how can you go on negative side???
Why we use pi in area of circle. It is a ratio betwen circumfe..and diameter. We use ratio in area of triangle also....why? Please make video on this..
Hi bhayya I have another explanation to it, with white balls and black balls. White is positive and black negative. Now if I take 10 white balls and add 4 black balls, it becomes 6. If I remove the ball it is minus and if i add it is plus. So if I again remove 2 times 2 black balls it is -2 * -2 , the result is 10 which is 6 plus 4. Hence -ve times negative is positive.

Respect man! Like he's solving the problem that we couldn't understand in years, in just 3 mins.
(-a+a)*(-b+b)=0 but expanding the brackets gives (-a*-b)-2ab+ab=0 giving (-a*-b)-ab=0 therefore -a*-b=ab where a and b can be any number.
I failed to understand why this answers the "Why" part; as in, I see the ritual and how it leads to the answer, but the "why" ?
To understand why, learn group theory and ring theory in maths. You'll know 'why' then.

Nganba meetei welcome
Superb questions. ..
I think this is the greatest question we should ask every mathematician brother...
Let's say you owe bank Rs. 100 in account A. That means your balance in account A is -100.
Now let's say the bank owes you three times as much amount in another account B. What is your balance in account B?
Since the direction of "owing" has changed compared to account A, the multiplier will be -3. Balance in account B is therefore -3 x -100 = 300... The positive sign showing that bank owes you this amount, unlike account A where you owe the bank.
Hope this clarifies...
In the example given by Nganba, both accounts have negative balances and since direction of "owing" is same in both accounts, multiplier is 2. In both accounts if you had -100 balance, total balance will be 2x-100 = -200. Negative balance shows you still owe the bank...

This is not a “why answer”
This just a “how answer”
This video explain you how to solve a minus x minus
"How answers" takes you to "why answers"
Why answers' means that "because of the math rules"
So,"why answers" comes from the math rules.
Therefore, İf you ask why -*-= +
The answer is because of the rule.
The rule comes from discription that who made it or realised it.
For example, does the one as a number exist?
No!
So ,how did it appear?
Or what is that "1" then ?
Where does the "1" come from?
The "1" come from hypothesis.
Someone made a stick and called it as "one". And anotherone give a sembol which is "1".
So,another numbers created like that.
What is the relation between nımbers and "why ansfer"?
The relation is hypothesis and, rules comes from hypothesies
İf you proff your hypothesis by calculating over the discbricrion terms,then your hypothesis becomes a rule.
So in math, there is no exact "why answers "
Because all rhe math concept comes from hypothesies.
you are making maths very interesting. thank you so much sir.
Welcome :)
Most bogus explanation i have ever heard ! I mean, WHY shall the first sign tell me which side i shall face ! WTF !
Do you have any better explanation than this....? If yes please put it on TH-cam. I would love to see it.
@@jahidulislamahmed2567 yaa, better than nothing 😊
This video is just bullshit. But sadly most people will now start believing this bogus explanation.
It's same as if asking ,why does a number scale have zero in centre, and negative and positive numbers on either side and that too to infinity and why not just to ten... Lol... Some people can't accept good explanations...
@@rohikmicka2624 hahaha good explanation?? There must be a logic to explanations.. anyways please feel free to believe whatever you want, its your choice !
The operations are representations of logic statements we must read to the end to compute them correctly. -2 × -3 = 6 is read "minus two times minus three equals six." We speak "We don't have time" or "we have no time". But if we say "we don't have no time" we are telling a logical riddle that can be translated in terms of time as "we have time".
but u never mentioned y? -ve × -ve = +ve. YYYYY?
He did.First,you should face the positive or negative direction on the number line and move in steps,either backwards or forwards.
reshabh verma maths ain't for ya
You should leave mathematics
joe you are amazing 😂😂😂
actually it's not "WHY" but it was "HOW".
Well explained. Visualization gives better understanding.
Thank-you :)
Well that's stupid
Thank God there is someone here who said this. Most people are hailing him as some genius "guru". :(
Awesome explanation sir..! ❤️❤️
The answer came positive because this process followed a pattern and I can explane it better than you
Explain it.
Amazing!! Never really thought about it!! Great job and so simple for everyone to understand
This is rather an idiotic expression without quantitative gain from WHYs. A clickbait!!
Really appreciate your skills in teaching, I have been search every help , but not one help me to understand this . Only you could get me to figure this rule, Thank you sir for your kindness 👍👍👍.
That Star Wars number line was awesome.
I am glad you liked it :)
Amazing explanation, truly amazing
Sir the way of your explaining is very nice.post some more videos in hindi bcoz my english is weak
You said the first letter let us know which direction I face and the 2nd number tell us in which direction we walk. Now in the case of -2 & +3 how can you go on negative side???
Wow! Great. Thank you for such a nice explaination . I have done Btech, Mtech but still I am mesmerised by your explaination.
How do you find (a-b)^2?
Nice explaination thank you sir!!!!
Why we use pi in area of circle. It is a ratio betwen circumfe..and diameter.
We use ratio in area of triangle also....why?
Please make video on this..
Hi bhayya I have another explanation to it, with white balls and black balls. White is positive and black negative. Now if I take 10 white balls and add 4 black balls, it becomes 6. If I remove the ball it is minus and if i add it is plus. So if I again remove 2 times 2 black balls it is -2 * -2 , the result is 10 which is 6 plus 4. Hence -ve times negative is positive.
awesome explanation,thank u....
Soo great.. sir.. you are really a great teacher
How you decided? The first number tells where u face nd to walk???
In adding there’s only walking forward or backward but in multiplying there’s facing and walking, get it now ?
Luv you bawa ji.... Your methods are real magic
Plz elaborate with another example...
it is good but not exactly as (a+b) the hole square
