Here are the results. Note: ":" is division.

1. -96 + 96 = 0
2. (-3) × (+19) = -57
3. 0 × (-88) = 0
4. +4 − 52 = -48
5. -60 ÷ (-12) = 5
6. (-92) ÷ (+1) = -92
7. (+2) × (-34) = -68
8. -37 − 9 = -46
9. 32 − (-8) = 40
10. (-4) + (-62) = -66
11. -75 + 0 = -75
12. +72 ÷ (+3) = 24

If you intended problem 10 to be a different operation (e.g., division), let me know and I’ll recalc.
