Prove that any two matrix expression is equal or not calculator
Matrix A :

 1 2 3 0 1 0 2 3 1

1. [[1,0,0],[0,1,0],[0,0,1]]
2. [[2,3,1],[0,5,6],[1,1,2]]
3. [[2,1,-1],[1,0,-1],[1,1,2]]
4. [[3,1,1],[-1,2,1],[1,1,1]]
5. [[5,6,1],[0,2,3],[1,1,2]]
6. [[5,-1,1],[-2,3,4],[1,1,7]]
7. [[2,3,-1],[3,2,1],[1,-5,3]]
8. [[1,1,1],[2,-1,-1],[1,-1,1]]
9. [[1,1,1],[1,2,3],[1,4,9]]
Matrix B :

 1 2 3 0 1 0 2 3 1

1. [[1,0,0],[0,1,0],[0,0,1]]
2. [[2,3,1],[0,5,6],[1,1,2]]
3. [[2,1,-1],[1,0,-1],[1,1,2]]
4. [[3,1,1],[-1,2,1],[1,1,1]]
5. [[5,6,1],[0,2,3],[1,1,2]]
6. [[5,-1,1],[-2,3,4],[1,1,7]]
7. [[2,3,-1],[3,2,1],[1,-5,3]]
8. [[1,1,1],[2,-1,-1],[1,-1,1]]
9. [[1,1,1],[1,2,3],[1,4,9]]
 Find : (A * B)' = B' * A'(A * B)^-1 = B^-1 * A^-1Adj(A * B) = Adj(B) * Adj(A)A * Adj(A) = |A| * IAdj(A') = Adj(A)'(A')^-1 = (A^-1)'
