WebIn the case of real numbers, the inverse of any real number a was the number a-1, such that a times a-1 equals 1. We knew that for a real number, the inverse of the number was the reciprocal of the number, as long as the number wasn't zero. The inverse of a square matrix A, denoted by A-1, is the matrix so that the product of A and A-1 is the identity matrix. WebBut for now it's almost better just to memorize the steps, just so you have the confidence that you know that you can calculate an inverse. It's equal to 1 over this number times this. a times d minus b times c. ad minus bc.
