Commutative Property of Multiplication
The commutative property of multiplication states that the order in which two numbers are multiplied does not affect the product. For any real numbers and :
For example, and , so . No matter which factor is written first, the product remains the same. Together with the commutative property of addition, this property allows numbers to be reordered freely within sums and products — a technique that is especially useful when rearranging terms makes a calculation simpler.

A logistics manager is calculating the total weight of a shipment containing 25 crates that weigh 40 pounds each. They realize that calculating 25 times 40 gives the same result as 40 times 25. Which mathematical property allows for the order of these factors to be swapped without changing the total weight?
A retail manager is calculating the total cost of an order of 50 tablets priced at 200 dollars each. Whether they multiply 50 by 200 or 200 by 50, the total cost remains 10,000 dollars. This mathematical principle is known as the ____ Property of Multiplication.
An inventory manager is calculating the total number of items in a shipment. According to the Commutative Property of Multiplication, multiplying the number of boxes (20) by the items per box (5) will result in the same total as multiplying the items per box (5) by the number of boxes (20).
