If A = [aij] of order m x n and B = [bij] of order m x n then their sum A + B is the matrix C = [cij] of order m x n where cij = aij + bij,
i = 1, 2, 3, ...... , m, j = 1, 2, 3, ...., n.
Two matrices A and B are said to be conformable for addition if they have the same order (i.e., same number of rows and columns).
Note: If A and B be matrices of different orders, then A + B is not defined.
The following is the demonstration of Addition of two Matrices.
Now, Let's jump in to have fun, Practically trying them...
