Provide an appropriate response.Use an example to explain the difference between the associative and commutative properties of multiplication.
What will be an ideal response?
Answers will vary. Possible answer: The associative property of multiplication lets you group numbers such as in the example 5 ? (8 ? x) = (5 ? 8) ? x. The commutative property allows the order of the numbers to be reversed in multiplication. For example, 5 ? (8 ? x) = (8 ? x) ? 5.
