2. 1-5: ADDING INTEGERS p.23

3. ADDING INTEGERS SAME SIGNS: add and give the common sign.
DIFFERENT SIGNS: find the difference, and give the sign of the larger absolute value.

4. EXAMPLE – same sign =
14 and 9 are both positive. Add and the answer will be positive.
= 23
(-5) + (-8) =
(-5) and (-8) are both negative. Add and the answer will be negative.
(-5) + (-8) = -13

5. TRY THIS
(-5) + (-1) = =
(-100) + (-52) =

6. TRY THIS
(-5) + (-1) = =
(-100) + (-52) = -6

7. TRY THIS
(-5) + (-1) = =
(-100) + (-52) = -6 28

8. TRY THIS
(-5) + (-1) = =
(-100) + (-52) = -6 28
-152

9. EXAMPLE – different signs
7 + (-18) =
signs are different
subtract
give the sign of the larger absolute value.
(-18 is negative so the answer is negative.)
7 + (-18) = -11

10. TRY THIS =
60 + (-13) =
12 + (-52) =

11. TRY THIS =
60 + (-13) =
12 + (-52) = -6

12. TRY THIS =
60 + (-13) =
12 + (-52) = -6 47

13. TRY THIS =
60 + (-13) =
12 + (-52) = -6 47
-40

14. p.25 Example 5
-12 + (-6) (-2)

15. p.25 Example 5
-12 + (-6) (-2)
(-2)
-3 + (-2) -5
