In the case of real numbers, the inverse of any real number a was the number , so that a multiplied by equaled 1. We knew that the inverse of a real number was the reciprocal of the number, as long as the number was not zero. The matrix is the inverse of a square matrix A, denoted by , such that the product of A and is the identity matrix. The resulting identity matrix will be the same size as matrix A.
