The determinant is a special number that can be calculated from a matrix. The matrix has to be square (same number of rows and columns) Inverse of a Matrix using Minors, Cofactors and Adjugate. We can calculate the Inverse of a Matrix by: Step 1: calculating the Matrix of Minors, Step 2: then turn that into the Matrix of Cofactors, Step 3: then the Adjugate, and Step 4: multiply that by 1/Determinant.
