Ma'am I didn't understand one thing. On 1:19:01 we have taken these two matrices. Since we are only given the data and we make matrix B as A and A as B, then our answer completely changes, i.e as it's in m*n (1*3) order and n*p (3*1) order resulting into m*p order of C (1*1) and now with opposite row and coloum it will be the opposite resulting into C (3*3). I hope you got my question. How will we understand when do we have to take out 3*3 and when 1*1 here because if the Matrices are changed the order completely changes.
Whenever we are multiplying any two matrices, example : a x b and b x c. there is one mandatory condition that we have to follow be have to see that if b=b, as in given example the condition is satisfied. a x c will be the order of the product of two matrices. Example: If order of A matrix is 4 x 2 and B matrix is 2 x 6. Here the condition is satisfied 2=2 and the order of the product is 4 x 6. If condition is not satisfied the product of the Matrices does not exist.
@@saeemuthe2387 in that given question, ma'am has taken 1*3 as the order of first matrix and 3*1 as the second right! If we are taking first matrix ie, about the books as 3*1 and price matrix as 1*3 then also this condition is satisfied..no.. I'm bit confused! Can you answer this one also..
I m in first year college now ...just came here to thank you ma'am....your videos have always been helpful for me in both 11 th and 12 th ....i passed my 11 th exams just by watching your videos...Thank you for everything ma'am....You deserve the best!!!

1:17 if you multiply row matrix with columns matrix then you will get 3*3 matrix, but if you multiply column matrix with row matrix you will gat 1*1 matrix and this 1*1 matrix is equal to the sum elements of main diagonal of initial 3*3 matrix.

is zero matrix a diagonal matrix? or if one of the element of main diagonal is zero for a 3x3 matrix then is it a diagonal matrix? for example- | 3 0 0 | | 0 0 0 | | 0 0 2 | & [0]

Shouldn't it be R2 -> 1/5 R2 ?

Thank you ma'am it is really a good introduction of matrices how easily u explained it. I wanna ask u that how r u intelligent in every sub. I know it is a strange question but I'm curious to know
Ma'am ,I have a doubt regarding question [q.1 ] -find the values of x y z from the following i.e x+y z ,5+z = second matrix i.e 6 2,5 8 ...but what if the order of the matrices is different then how to find the values?
just follow the same process

Mam your teaching skill is too good even our teachers are failed to explain topics with this much ease and intrest
1:50:22 a small correction, it should be R2-->(1/5)(R2).
Thank you for the explanation
1:17 if you multiply row matrix with columns matrix then you will get 3*3 matrix, but if you multiply column matrix with row matrix you will gat 1*1 matrix and this 1*1 matrix is equal to the sum elements of main diagonal of initial 3*3 matrix.
What we see simple behind it there is a lot of hard work of learnohub. Thanks ma'am.

is zero matrix a diagonal matrix?
or if one of the element of main diagonal is zero for a 3x3 matrix then is it a diagonal matrix?
for example-
| 3 0 0 |
| 0 0 0 |
| 0 0 2 |
