A true guide on math subjects. Not like other articles where they just write about weird unreadable equations with no proper explanation.
Watching this really makes us learn it fast.
Wow. This is what I failed in high school? Howww? It makes so much sense now. God I wish I could redo high school
SomeReallyWeirdGuyLostOnUA-cam Lul no u don’t
Its never too late to learn!!

That feeling bro
That feeling bro
My maths teacher “teaches” us about matrices as if he think we already know it all. He brain dumps everything on the whiteboard and expects us to follow. Some of us just don’t understand it. Someone’s talent with maths isn’t based upon how much they already know, but how well their ability to learn things is, and he just doesn’t give us that opportunity. Thanks for this, really helped.
yes for real
That's because he's great at maths and terrible at teaching
My teacher

MR. Organic Chemistry Tutor, thank you for another solid Linear Algebra video/lecture.
best teacher ever
This is the most incredible and easiest video on solving matrix. Thanks a lot
You make it so easy to comprehend, thanks so much
Hello, just wanted to say i love your videos and they are really helping me with matrices. I noticed that you haven't posted a video about Rank and Range though, i think that you should!
Your voice is soothing. Thanks for these!
I'm here bc i have a math exam in 4 days and let me say you taught me better than all my math teachers
@@AmakaEzeokoli it was mid
THANK YOU SO MUCH, I ACTUALLY FOUND IT HELPFUL....IT HAS ABOLUTELY HELPED ME..
ABSOLUTELY I MEANT TO SAY..
Sir thanks very much for helping not only student's but even people who are not schooling, because you provide just exactly what we want, I wish you where my teacher , because since I started watching your video I eventually become a genius in both mathematics and physics, thanks once more, may God bless you.
Just wanna thank you coz really I had missed out on my lecture of matrices it was giving me had time but now I can do it 🙏 .
Thank you, your videos are helping me a lot.
Great instruction. Thank you!
Best UA-cam channel thank you
you are saving me. thank you
very help ful video thnaks for your help
Thank you!! Getting through linear algebra because of you!!
Thanks it really helped me a lot 😊😊
who else is here because this type of question was on the ACT and you never learned it?
God bless you Sir
Very easily explained. Tumbs for you 👍👍
Not exactly what I was looking for but you really are a good teacher, thank you so much.
But am kindly asking how i can solve a metrics problem where by i have a variable in the matrix, for example
A=(1 4) and and B(5 3) then asked to solve for "y"
(3 y)
What?
Thank you sir your work is appreciated.
this really helped !!!
Since you start with numbers in the two "example" matrices implies that you're going to tie it into your equation. I'll use your method without the 2 first matrices since you got a positive result. I'm working with augmented matrices, inversion, multiplying matrices etc. I'd like to see your logic since it works. I could resolve the original equation with arithmetic methods but it IS about matrices. Thank you.
Great explanation. Thank you.
this video was very helpful. thanks bro
Wow, thank u so much
You have always been the best, thank you so much so much ❤️
Thanks bro 😀😀
Why does the scalar matrix turn to positive after multiplying?
Wow, this is way easier than I thought
thanks bro
How about
Given matrix x=(0 -1)
(-3 2)
Find B if x² =B+x
merci
Thank so much ❤❤❤❤
Thank you sir❤
Consider Cayley Hamilton Theorem also
Thank you, atleast now l can say that l know maths
Thanks I didn’t pay attention in class 😂
Where did you get the 3A and the 2B?
It'll be given to you
???
What if the variable matrix X had a coefficient A which is another given matrix? How will I solve that one?
quick question: why is a positive sign left over?
Who watching this video in Year 2024
✋🙂↕️
The day before finals 😢
Hey champ👊
2:59 sounds like @TheOrganicChemistryTutor bout to drop a song with The Weeknd
thank u
How did the 3 became -3 in the 2B - 3A? Is the operand before the 2nd given Matrix should adapt the operand sign before it?
I can help, but you need to pinpoint the exact time of the step you are confused by
what software does he use to draw.
Me watching in 2025 my best teacher .
Atleast I've learned something 😌
Why did you add the two matrices instead of subtracting them in the first example?
because he already used the negative sign in the equation. it automatically turns it into a plus sign.
@@oyunboldganbaatar7501 Thanks!
@@oyunboldganbaatar7501 thanks i
It’s fucking 3 am and my homework is due 5 hours later
Why do we divide by negative 2 at 3:52
?
At 1:56 can anyone elaborate why we put a + in front of the matrix ?
Does it mean that if it's + sign, it should be negative(vice versa) after multiplying?
Where did 3A came from?
row 1 column 1
It’s part of the given question
Pls how do you get the number you used for the equation
The 6B and the 2A
Me watching this in 2024 😐
you only did easy ones. how do u solve for one with a matrix as a coefficient of X
Hey i was watching this video but am asking where did you get this 6A and 4B,??
why does he switch -2 to + after multiplying by -2
because 2 - 3 is the same as 2+(-3)
I have a problem with this.
I don't really believe in being able to divide through when two numbers are in subtraction.
I guess that's why I got different answers when I tried to do the 6A-2x=4B
So please can you explain more under this comment.
Thank you
Sir, one question! Can we just directly write 3A+X=2B as X=2B-3A without substracting 3A+X=2B by 3A?
an hour before my quizz😂
3:55 why are you dividing by -2
nakakatuwa kasi wala talaga napasok sa utak ko
But where you bring this x sir? 🥺🥺
If i have matA and matB and i have the equation AC-CA=B
How to find the matrices C ?
It depends upon the order of A and B right??
bro thank you
2B-3A
Feels that + should not be there?
2:00 and 5:00 Can someone explain why does the - sign changes to + sign??
It’s the matrix inverse formula
how do you find x when it is inside a matrix with a number?
Even me am searching that the whole day
If you are subtracting 2A throughout the equation to get rid of it on the left side, wouldn't you also need to subtract 2A from X ?
2A - 2A = 0 so its gone
I don't know how to get 3A + X = 2B ? 🤔
X= 2B-3A🤦♂️
It’s the GIVEN question u get given the A matrix and the B matrix and you solve for X
@@amkai2928 but why did he then add the matrix?
not me watching this during class -
I don’t understand how he got 2b
2b was the part of the given question
Where do we find 2B
Why are you adding the matrices if the equation states you need to subtract them
That's what I thought at first, but he multiplies the Marix by the Negative coefficient (-2), therefore, he adds the remaining matrices.
When he multiply all the elements in the matrix by a negative number, the sign in front is positive.
@@rachaeladdo5302 why though
@@ronymeri4744 I was confused too
I was confused for like 20 minutes also on why multiplying the 2nd matrice by -2 and replacing the formula instead of multplying it by 2 and doing the substraction after regularly.
@ 0:33
Jazakallah
Why did you multiply Matrix B by 2? Where does the 2 come from this wasn’t explained thoroughly for my understanding. Ok we subtract each side by -3A, 3-3A cancels out, cool, 2B - 3A = -1. Ok what happens with the -1? Then suddenly we have to multiply by 2 but why?
The 2 came from the random equation, nothing else.
@@Max-eg5gc 😩
👍👍👍🥇
But why is that u convert -2 to positive 3,pls can anyone help me
No division
Ue Ar Veri Quiet
Please 🙏🥺 can you help me ?
My givan equation is 3A + 5B + 2x = 0. It can not devide by 2 in both side to get X. How to get X = ......... From this given formula to solve my prob.. 🚫Plz plz plz help me...
My friend don’t cheat in exam😂
how would you solve: (AA^T)^-1 * ((B^T * (AA^T))^T
I am king👑
I to I don't understand
Webale nyo
♥️♥️♥️♥️💪😎
I really don’t understand how 6+[-8]=-2 and 27+[-6]=-21
Simple math😊
Yes i am commenting on all of his vids complamenting him
no i am not correcting my spellings and YES I WILL CONTNUE THIS
I don't understand 😢😢
