This document discusses rules for adding integers. It explains that when adding integers with the same sign, the sum has that sign, and when adding integers with different signs, the sign of the number with the larger absolute value is kept. Examples are provided of adding different integers together according to these rules, such as -3 + -2 = -5 and -7 + 9 = 2. The document concludes with exercises asking the reader to find the sum of several integer expressions.

5. -5 + 3=
Adding Integers

6. Another way to
think of it
-7 + 9 =
-4 + -2 =
5 + -3 =
Lose 7 Win 9
Lose 4 Lose 2
Win 5 Lose 3

7. Adding integers
with the same sign
Adding integers with
different signs
1.2 + -7 = 1.-5 + 9 =

8. Find the sum
1. -6 + -4 =
2. 5 + -9 =
3. -3 + 7 =
4. -2 + -8 =
5. 7 + -7 =
6. -5 + -5

9. 1
-7 + (-5) =

10. 2
- 10 + 12 =

11. 3
-6 + -2

12. 4
-9 + 6 =

13. 5
-3 + 8 + (-9) =
