Subtraction of two matrixes:

Rule: Subtraction of two matrixes is only possible if both matrixes are of same size.

Suppose two matrixes A and B is of same size m X n

Subtraction of two marixes is defined as

(A - B)ij  = Aij - Bij
Where 1 i  m and 1 ≤ j  n

For example:
Suppose two matrixes A and B of size of 3 X 2 is as follow:
