If A = [ aij ] and B = [ bij ]
are two matrices of the same order, say m × n. Then, the sum of the two matrices A and B is defined as a matrix C = [ cij ] m × n, where cij = aij + bij, for all possible values of i and j.
The two matrices have to be of the same order. if A and B are not of the same order, then A + B is not defined
