1. Objective: 1. Learn to use inverse operations.

2. 4.1 Inverse operations
Suppose that you ride your bike north for 4 miles, and then decide you need to return home, where you started. What would you have to do? _____________________________.
Riding north and riding south are inverse actions because they undo each other.

3. If you add 5 to a number and you want to return to the original number, you started with, you would subtract 5.
Addition and subtraction are inverse operations because they “undo”each other.
Undo each action. Find the inverse operation.
