How to find the Inverse of a Matrix 

The inverse of matrix is another matrix, which on multiplication with the given matrix gives the multiplicative identity. For a matrix A, its inverse is A⁻¹, and A.A⁻¹ = I.
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.
