Question

Directions: Simplify the following expressions. Refer to the rules for signed numbers in solving these problems.
Example: - 4 + 5 = +1 (the signs are different, take the difference (subtract) and place the sign of the larger number)

1. + 2 - (+3) =

2. + 11 + (-10) =

3. 3 + (-5 ) =

4. + 22 - 21 =

5. - 8 - (-44) =

6. -12 - (-6 ) + 3 =

7. + 16 -(-12) =

8. - 36 - (-36) =

9. -4 * 10 =

10. -1 * -1 =

11. + 7 * - 7 =

12. -4 / 4 =

13. -7 * -5 =

14. -10 * + 8 =

15. -2 * - 7 =
