2 Algebra tiles can be used to add or subtract integers. Remember integers are.

3 Example 1: Use algebra tiles to represent = = = =

4 Neutral pairs have a value of _____. zero = 0

5 Example 2: A. Use algebra tiles to represent and then cross out any neutral pairs. +=

6 B. Use algebra tiles to represent and then cross out any neutral pairs. ==

7 C. Use algebra tiles to represent and then cross out any neutral pairs.

8 D. Use algebra tiles to represent and then cross out any neutral pairs. =

9 E. Use algebra tiles to represent and then cross out any neutral pairs. There are no neutral pairs =

10 F. Use algebra tiles to represent and then cross out any neutral pairs. There are no neutral pairs =

11 Rules For Adding Two Signed Numbers: A. Signs are the same – 1.______________________________________ 2.______________________________________ Add the numbers Take the given sign B. Signs are the different – 1.______________________________________ 2.______________________________________ Subtract the numbers Take the sign of the larger number

12 Example 3: Find each sum. A. B. C. Signs are the same Signs are different Signs are different Try these… Find each sum. A. B. C.

13 Example 4: Find each sum. A. B. C. D

14 Try these… Find each sum. A. B. C. D.
