just one argument, a second Matrix which we will refer to as B, and modify A if the dimensions of A and B
match. If the dimensions match, the functions should return true, otherwise they should return false.
Addition of two matrices, C = A + B, and subtraction of two matrices, D = A − B are formally defined as:
(∀i,j |i ∈ {0, 1, . . . , m − 2, m − 1}, j ∈ {0, 1, . . . , n − 2, n − 1}) Ci,j = ai,j + bi,j
(∀i,j |i ∈ {0, 1, . . . , m − 2, m − 1}, j ∈ {0, 1, . . . , n − 2, n − 1}) Di,j = ai,j − bi,j
