Week 16, Day 2

As we continued our review of the semester, we dove into the concept of matrices.
In her presentation, Jasmine explained how to perform inverse matrices.

A^-1 is called the inverse of A.

Show that B is the inverse of A where, 

To show that B is the inverse of A, show that AB = I = BA, as follows.

If a matrix A has an inverse, A is called invertible or nonsingular; otherwise, A is called singular. A nonsquare matrix cannot have an inverse. The following are example problems I took from my original post on the topic demonstrating how to solve for inverse matrices (one is singular and one is not).
