What is the associative property of multiplication?

Back

The associative property states that the way in which numbers are grouped in multiplication does not change the product. For example, (2 x 3) x 4 = 2 x (3 x 4).

Front

What is the commutative property of multiplication?

Back

The commutative property states that changing the order of the numbers in multiplication does not change the product. For example, 4 x 5 = 5 x 4.
