Answer:

Explanation:

1. + 2 - (+3) = 2 - 3 = -1

2. + 11 + (-10) = 11 - 10 = 1

3. 3 + (-5 ) = 3 - 5 = -2

4. + 22 - 21 = 22 - 21 = 1

5. - 8 - (-44) = -8 +44 = 36

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

7. + 16 -(-12) = 16 +12 = 28

8. - 36 - (-36) = -36+36 = 0

9. -4 * 10 = -4 × 10 = -40

10. -1 * -1 = -1 × -1 = 1

11. + 7 * - 7 =7 × (-7) = -47

12. -4 / 4 = -1

13. -7 * -5 = -7 × (-5) = 35

14. -10 * + 8 = -80

15. -2 * - 7 = 14
