Associative property of multiplication review

Review the basics of the associative property of multiplication, and try some practice problems.

What is the associative property?

The associative property is a math rule that says that the way in which factors are grouped in a multiplication problem does not change the product.
Example:
5, times, 4, times, 2
Let's start by grouping the start color #11accd, 5, end color #11accd and the start color #11accd, 4, end color #11accd together. We can evaluate the expression step by step.
empty space, left parenthesis, start color #11accd, 5, times, 4, end color #11accd, right parenthesis, times, 2
equals, start color #11accd, 20, end color #11accd, times, 2
equals, 40
Now let's group the start color #7854ab, 4, end color #7854ab and the start color #7854ab, 2, end color #7854ab together.
empty space, 5, times, left parenthesis, start color #7854ab, 4, times, 2, end color #7854ab, right parenthesis
equals, 5, times, start color #7854ab, 8, end color #7854ab
equals, 40
Regrouping does not change the answer!
