1. + Subtracting Integers on a Number Line

2. + How to subtract integers on a number line This will be similar to adding integers on a number line, but instead of adding, we will be subtracting. Place a circle on the number line to represent the first number in the problem. The second number will tell you how much to take away (this is different from addition because now we are subtracting. If the second number is negative you will move to the right. If the second number is positive you will move to the left. The number you end on becomes your answer.

3. + Example 1 Model 5 – 2 on a number line Start at 5 on the number line Take away 2, move two spaces to the left (since the 2 is positive) Answer: 3

4. + Example 2 Model 5 – 8 on a number line Start at 5 Move 8 spaces to the left (since 8 was positive) Answer: -3

5. + Example 3 Model 5 – (-2) on a number line Start at 5 Move two spaces to the right (since 2 was negative) This is the opposite of what we did for example 1 Answer: 7

6. + Example 4 Model 3 – (-4) on a number line Answer: 7

7. + Example 5 Model 6 – 10 on the number line below Answer: -4

8. + Example 6 Model -5 – (-5) on a number line Answer: 0

9. + Example 7 Model -8 – (-12) on a number line Answer: 4

10. + Example 8 Model 7 – 9 on a number line Answer: -2

11. + Example 9 Model -3 – 6 on a number line Answer: -9

12. + Example 10 Model 4 – 10 on a number line Answer: -6
