If  and, then verify that
 and, then verify that
(A + B). = A’ + B’

(A+B)’ = A’+B’
Explanation: Calculate matrix A by taking transpose of A’ and also find the transpose of matrix B and the solve L.H.S and R.H.S separately and then compare the result.
So, A = transpose of A’

B’ = transpose of B







From equation 1 & 2 we verify that
(A+B)’ = A’+B’. Hence verified.
