17 Each day, about 75,000 people visit Paris,
France. Use the Commutative Property to
write two equivalent expressions that could
be used to find the number of people that
visit over a 5-day period. (Example5)

You can represent the total number of visitors over a 5-day period using the expression 75,000 x 5, which equals 375,000 visitors. By applying the Commutative Property, you can also write this as 5 x 75,000. Both expressions highlight the same total number of visitors, demonstrating how multiplication can be rearranged without changing the product.

This concept of the Commutative Property isn’t just a math trick; it reflects the logical way we can understand and manipulate numbers in everyday situations, like estimating crowd sizes for events or calculating potential sales in a busy tourist season. It helps mathematicians and consumers alike simplify problems and make informed decisions.
