Some matrices are non-conformable, so you can't multiply a 4x3 matrix by a
4x3 matrice but you can multiply a 4x3 by a 3x4.

For example:

a = [1, 2, 3]
b = [3, 5, 7]

You can multiply a by b because they're non-conformable matrices.
And also matrices are not commutative or associative under multiplication.

Or was that what you meant anyway?
