Answer:
Step-by-step explanation:
1. + 6 - (+3) = 3
2. + 10 + (-10) = 0
3. - 3 + (-3 ) = -6
4. + 24 - 21 = 3
5. - 48 - (-44) = 92
6. -12 - (-4 ) + 3 = -5
7. + 16 -(-15) = 31
8. - 35 - (-36) = 1
9. -6 * 10 = -30
10. -10 * -10 =100
11. + 7 * - 7 = -49
12. -4 / -4 = 1
13. -6 * - 5 = 30
14. -10 * + 7 = -30
15. -4 * - 7 = 28
