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  = A_ij - B_ij

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:
