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, 3 x 4 = 4 x 3.

Front

What is the associative property of multiplication?

Back

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