In school life, I learned matrix inverse for getting numbers to pass math papers but now I learn matrix inverse as a professional. The credit goes to Sir AMMAR.

Identity matrix is matrices which on multiplication by actual matrix does not effect the real matric. It have 'all elements 1 ' in diagonal.. A Inverse = changed matrix / determinant of matrix

and inverse in correct when matrix X inverse = Identity
A=[

AOA,
In this lecture, I learned about the inverse of a matrix and its steps. I also learned that if the determinant is zero, the matrix does not have an inverse.

I have done multiplication and I learned to determine an Inverse matrix.
