1) Go to the textbook site, my.hrw.com.
2) View Lesson 6-5, Example 1 (Percent increase/decrease)
3) Jot down some good notes as the video plays.

If you are as excited as I am, then why not also view Lesson 6-5, Example 2 and perhaps Example 3!

Random Glossary Entry

associative property

This states that when you add or multiply, you can group numbers in any combination.
(a + b) + c = a + (b + c)

m * (n * p) = (m * n) * p

For example:
(2 + 3) + 4 = 2 + (3 + 4)
Another example:
2 * (3 * 4) = (2 * 3) * 4
