Answer: Hello there!
An operation is commutative if changing the order of the factors does not affect the product, this property works for addition and multiplication:
The commutative property for addition is, for two real numbers A and B:
A + B = B + A.
The commutative property for multiplication is, for two real numbers A and B:
A*B = B*A
This is not necessarily the case if we are working with functions, complex numbers or matrices.
