Multiplying Whole Numbers with Number Line

Multiplying 5 × 3 can be thought of as making 5 groups of length 3. The total length is 15, so 5 × 3 = 15. The Commutative Property of Multiplication states that changing the order of products does not change the result. So 3 × 5, or 3 groups of length 5, also has a length of 15.
