    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.

I was very afraid that , i will not pass without coaching . But your videos have saved my life ❤ The only reason i passed my 12th grade was because of your videos . I give a big credit of my success to you .I still can not believe that this much incredible content is free of cost and available for everyone . Your favourite lines are incraved in my head for forever like " hello and welcome to learnohub " or those memorable lines of " Crystal clear " 💙 Your channel will be very nostalgic and memorable for me . Thankyou so much for all your hardwork in providing quality education with very easy techniques and understandable visualisations . 😊 May you keep educating more and more childrens like this .
