The inverse of a matrix A is A⁻¹, just as the inverse of 2 is ½. We can solve equations by multiplying through by inverses; it's similar with matrices.
Verify that multiplying a matrix by its inverse results in 1. Use matrix multiplication to find the inverse of a matrix. Find an inverse by augmenting with an identity matrix.We know that the multiplicative inverse of a real number aa is a−1a−1 and aa−1=a−1a=(1a)a=1aa−...
