Inverse matrix introduction | Matrices | Precalculus | Khan Academy

Keep going! Check out the next lesson and practice what you’re learning:

The inverse of a square matrix is another matrix (of the same dimensions), where the multiplication (or composition) of the two matrices results in the identity matrix. This is analogous to inverse functions (if we think of matrices as functions) or reciprocal numbers (if we think of matrices as special numbers). Fascinating!

Wow 😳. what a class! This is greater than my school teacher's 1 hour lecture

would u still get the identity matrix if u did A^-1 times A?. because the multiplication of matrices is not commutative.
