Multiplication of two matrixes:
Rule: Multiplication of two matrixes is only possible if first matrix has size m X n and other matrix has size n x r. Where m, n and r are any positive integer.
Multiplication of two matrixes is defined as:

Where 1 ? i ? m and 1 ? j ? n
For example:
Suppose two matrixes A and B of size of 2 x 2 and 2 x 3 respectively:

Here A is a two
