Sir you missed one critical info for the pass code one 1313 is counted twice At 1 3 _ _ the space could also have 13 At _ _ 1 3 the space will also have 13, thus we counted 1313 twice hence the true answer is 10^4 - 299 = 9701
I swear you are going to be one of Malaysia most well known mathematics teacher. Start an online business already, take advantage of modern day opportunities. A man who can simplify yet sympathize with students who are immensely weak. A lifesaver for all. Good luck for the future Sir.

hey you've upgraded your videos! I'm so proud that this channel is still ongoing and that you are still doing free tutorials on addmaths. I used to watch your videos to prepare for spm2016 and I just wanted to say thank you for your tutorials, for making addmaths easier and for making education easily accessible by everyone :) I wouldn't have gotten an A for addmaths in 2016 if it wasnt for you, thank you and bless you mr matthew. Good luck to everyone studying for exams and dont take medicine just because your parents told you to alright hahahaha
You have to keep cool don't press on the panic button. In this type of question spend more time on reading the question because solving them is very fast by using the calculator. The examiner know that they themselves can't solve these type of question if it's not clear about the given constraints. Make sure it's HOT but really clear and don't put yourselves in HOT SOUP.
yeah i pity on you all,i am batch 01.but i will honestly say that this is good for you,because the style of f6 is like this,and i am struggle and just able to pass.i take science stream course,this make me face more difficulties .relax spm is more easier than stpm.but this cannot avoid because if u want to avoid stpm ,u will face it again in u.last i actually got 8Ain spm.
I see alot of these questions now in add maths books. They have this question alot most of the markingg schemes takes the “real world scenario” as the main answer and follow ur answer. I didnt get why it was always 299 but now i do thanks so much.
If I not mistaken the six passcodes that can be change got a little mistake , the second passcode has repeated and the actual anwer is 1103 not 0131. Forgive me I was wrong😓
To be honest, is it so hard to add few more words "using the numbers given" at the back of the question ? Is the one who write the exam paper that lazy or just have bad english, i am the 02 badge SPM student, and i got so mad cuz i got B+ becuz i did this question in the global scope
I hope after this, the examiner will set the paper and specify the constraints clearly to the students as this might confuses them during the examination.
To answer the 2nd method in a more untechnical way, just list the numbers and cancel whichever that do not fit the criteria 0113 - NO 0131 - NO 0113 - 2nd 0131 - 2nd 0311 - YES 0311 - 2nd 1013 - NO 1031 - YES 1103 - YES 1130 - NO 1301 - NO 1310 - NO 1013 - 2nd 1031 - 2nd 1103 - 2nd 1130 - 2nd 1301 - 2nd 1310 - 2nd 3011 - YES 3011 - 2nd 3101 - YES 3110 - YES 3101 - 2nd 3110 - 2nd So the answers are 0311, 1031, 1103, 3011, 3101, 3110
Man. My answer was 9699.. I calculated all possibilities with "13" inside and then got 300 possibilities. Then at the last 10 seconds my brain told me got one possibility which is "1313" that repeats twice but I forgot to take into account(Actually calculated it twice in 13XX and XX13) so should be 299 possibilities. But instead of: 10000 - (300-1) = 9701.. I did 10000 - 300 - 1 = 9699... ggwp
im not a smart addmath student but, i do have love for english and yes i agree with the use of "the" in the sentence which meant to indicate the digits mentioned. if my mind is not playing trick, the question in bm made it clear that it was asking for candidates to rearrange the digits mentioned. from my point of view, logically speaking, there must be a reason why they stated the digits in the first place. plus, if we look at the mrsm question, it does play trick with the language but it was however understandable. but now, im glad i answered 6😂 just a piece of my mind
i solved it by 4! (number of passcode he can make by using those 4 numbers) - 3!2! (which the passcode consists of digit 1 followed by 3), so by doing that only left the passcode which not consist of digit 1 followed by 3
Sir you missed one critical info for the pass code one
1313 is counted twice
At 1 3 _ _ the space could also have 13
At _ _ 1 3 the space will also have 13, thus we counted 1313 twice
hence the true answer is 10^4 - 299 = 9701
Ng Wei Yuan 9701

Ng Wei Yuan oh ya , I forgot about it . Thanks 🙏 I will pin your comment 💪🏼
Ymx+c I did reply too haha btw thank you sir for all your videos. It really helps me in the past two years
Should we minus the 0131 as well since the question wants us to reset the passcode? Means we do not want that 0131

Batch 02 SPM kinda messed up..like really messed up

addmath so hard but this teacher can still laugh while teaching
Anyway, I'm loving this new "format" of teaching!

Seriously, they need to make the question clear! I wasted time on that one and left it blank in the end

I didn’t even do that question?? I skipped it
Here comes depression..
oh shit here we go again
Sir 0131 is not fulfilled the condition it should be 1103
I see alot of these questions now in add maths books. They have this question alot most of the markingg schemes takes the “real world scenario” as the main answer and follow ur answer. I didnt get why it was always 299 but now i do thanks so much.
I really miss watching sir's videos so I can't wait to see you make a video on 2019's SPM Add Maths papers.
Till then, have a great New Year!
At 13:29 you rewrote the passcode...
Sir I think it is because of the word “reset”. It means you can just ignore the original passcode and solve the question using the real world scenario
I think 10000-100-100-99 =9701 because 1313 is counted subtracted in the cases 1x1x10x10 and 10x10x1x1 but not in 1x10x10x1
lmao i cant relate i didn't even get to answer this. threw a bunch of numbers before time was up and just prayed for mercy
this really heartbreaking
If I not mistaken the six passcodes that can be change got a little mistake , the second passcode has repeated and the actual anwer is 1103 not 0131.
Forgive me I was wrong😓

Is the one who write the exam paper that lazy or just have bad english, i am the 02 badge SPM student, and i got so mad cuz i got B+ becuz i did this question in the global scope
The two '1' cannot change theirs place?
Sir when listing manually the combination only using the four numbers 0131 is incorrect as it should be 1103
Ratchagga Subramaniam yes u are right 👍🏼
0131, isnt it the samw as the question
Can you make a video about the exclusive probablity...i was a bit confused
I hope after this, the examiner will set the paper and specify the constraints clearly to the students as this might confuses them during the examination.
Btw 0131 not digit 1 follow by 3?
Sir how about paper 1 last question?The standard deviation question
The answer is 2
I don't think it's only the 4 digit sir. I think it includes all the 10 numbers
Sir, can you please discuss the dart question in paper 2??? Question 8 please
some people do not understand the question. Fortunately I answered correctly. @02 gud luck kimia esok
To answer the 2nd method in a more untechnical way, just list the numbers and cancel whichever that do not fit the criteria
0113 - NO
0131 - NO
0113 - 2nd
0131 - 2nd
0311 - YES
0311 - 2nd
1013 - NO
1031 - YES
1103 - YES
1130 - NO
1301 - NO
1310 - NO
1013 - 2nd
1031 - 2nd
1103 - 2nd
1130
- 2nd
1301
- 2nd
1310 - 2nd
3011 - YES
3011 - 2nd
3101 - YES
3110 - YES
3101 - 2nd
3110 - 2nd
So the answers are 0311, 1031, 1103, 3011, 3101, 3110
Jeez i lost confidence on my addmath alr 😂. Maybe im just a bad student..
if you use the listing method, it should be 1103 instead of 0131, since you said it cannot be 1 followed by 3
0311
1103
1031
3110
3101
3011
different between the number of passcodes and the passcode
First question is 3!*4! isn't?
Sir, can you make videos for A-level Mathematics?
omg.....i think the ali? is it ali? has fix his passcode four digitss 0131 and he cannot pick the other omgg....i end up losing 3 marks now😞😞😞
His name is San and me too :(
I used the method like yours but I didn't divide 4 factorial over 2 factorial.i simply use 4 factorial.i got 12 as my final answer😂
I got 16 XD
cant really understand why the ans is 9701
I got 9000 something too but I'm not sure bout the exact number
Sir you are the Best everhhhhhhhhhh.... Salute you... I wrong here 😅😅😅
Yes! Just as I thought
A 15 minutes uncut video,that's incredible!! Thanks for solving this silly question from one of the worst paper created
Man. My answer was 9699.. I calculated all possibilities with "13" inside and then got 300 possibilities. Then at the last 10 seconds my brain told me got one possibility which is "1313" that repeats twice but I forgot to take into account(Actually calculated it twice in 13XX and XX13) so should be 299 possibilities.

10000 - (300-1) = 9701.. I did
10000 - 300 - 1 = 9699...

Kappa
Same as me 9699
Just press reset and reset

Exactly bro
Sir can you make pass year 2022 paper 1 10b? It is really confusing
Add math paper right ?
yes add math@@mathew_pang . about the passcode. I already see the scheme answer but I could not understand what they want actually.
"0131" 1 FOLLOWED BY 3 ...
MRSM question was way easier...but the SPM 2019 question was freaking hard for me 😂
0131 is wrong
My answer was 12 😂
23:20 ikr but everyone got 10k plus
Same 😆
Same here
@@sentoashnaidu3197 my friend got a really big number too because she had a similar thought proccess as sir's 😂
i'hv got no answer😂
i solved it by 4! (number of passcode he can make by using those 4 numbers) - 3!2! (which the passcode consists of digit 1 followed by 3), so by doing that only left the passcode which not consist of digit 1 followed by 3
how do u get 3!2!
I just do it my way. This is how👇
4!-(3!×2)=12
I want to be add math teacher one day...
I find a answer which is 27000....
Oh dear!
At least I right about 10x10x10x10
why am I watching this? i just passed upsr 😂
I get 124
i tried to do the question then ended up just merepek and i skipped it :))))
My answer is 9701. Because 1313 is repeated
Do you find Addmath exam this year very hard ?
Azizah Kasim I think is moderate
u are a monster
I just use trial and error 😂
I used permutation for this :(
Ya correct lol...
Lucky i igcse phew
0131 haha
Adric Teo ya that one is mistake 😅
This is one of the lan**u question
