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.

Whether it's my exams or just a normal day for me to learn new concept or it's my neet preparation time, u have always been such a great source of reliability for me for all this. I am old follower and is so happy to see you everytime coming back with same energy and enthusiasm for the kids u don't even know. Cant express the gratitude and huge amount of respect I have for u with words. Thankyou! ❤️
I stumbled upon this video after many months and just came here to show my gratitude to you ma'am . I did not join any coaching in 11th and 12th sci . 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 .
@@sumedhvats1395 yup, im in 12th now. picchle do saal ive spent time doing math instead of focusing on neet and now theyre telling me to score good marks in boards and neet :/
Ma'am idk whether u will see my comment or not but in the inverse matrix sum, u should have written apply 1/5R2 rather than 1/5R1 cuz even if we do it that way the sum will change a Lil bit atlast .... 🙏
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
Mam, Their are no videos on 12th more chapters of you. I want your more teaching videos on crash course 12th maths. I seen full 11th course. I like most it than other TH-cam videos. Plz make more videos on 12th maths crash course video, that you not teach till.

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?
MAM .....THANK YOU SO MUCH ......IT HELPS ME A LOT ......I HAVE NO WORDS TO DESCRIBE YOUR TEACHING STYLE......ONLY I CAN SAY IS THAT. ..KEEP IT UP ......WE ALL SUPPORT YOU ...
Hi mam, ur really great.....🙏🙏 You are the one who inspired a lot to me mam. If you don't mind can you please explain in English mam it's helpful a lot for all the student because English is easy to understand and more comfortable than hindi.......☺️

Problem 1
It proves associative property
A +( B - C) = (A +B) -C
=(A - C) + B
This may be proved according to associative property
Once again we may prove
A +(B - C) =(B - C) + A
in accordance with commutative property.

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.

Agar koi matrix A ( 2×4) order ki h aur koi dusri matrix B ( 4×3 ) order ki h toh
AB = Matrix ( 2× 3) order ki hogi pr ye toh possible hi nhi h.
Agar first matrix k column = second matrix ki row
Then must check
First matrix ki row = second matrix k coulmn k

I stumbled upon this video after many months and just came here to show my gratitude to you ma'am . I did not join any coaching in 11th and 12th sci . 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 .
Superb explanation. I have never seen such type of site before and it is far better than any paid website
