Suppose that A is nonsingular and To calculate inverse matrix you need to do the following steps. Set the matrix (must be square) and append the identity matrix of the same dimension to it. Reduce the left matrix to row echelon form using elementary row operations for the whole matrix (including the right one). As a result you will get the inverse calculated on the right.
