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
