The best response to convince your friend that changing the order of the numbers being multiplied will make the problem simpler is:
The Commutative Property of Multiplication says that changing the order in which you multiply the factors does not change the answer; a × b = b × a.
This property confirms that multiplication is commutative, meaning that the order in which numbers are multiplied does not affect the final product. Therefore, rearranging the factors can lead to a more straightforward calculation.
