Question 4 • RS AZ-US History A
Multiplying two rational expressions gives another rational expression, so multiplication has the closure property. Multiplication is commutative, meaning the factors can switch order without changing the product; division is not commutative. Division is also not associative, and associativity means regrouping factors does not change a product’s value. These properties parallel those for rational numbers.
