1) -96 + 96; 2) (-3) • (+19); 3) 0 • (-88); 4) +4 - 52; 5) -60 : (-12); 6) (-92) : (+1); 7) (+2) • (-34); 8) -37 - 9; 9) 32 - (-8); ;(10) (-4) + (-62 11) -75 + 0; 12) +72 : (+3).

Here are the results (assuming item 10 is (-4) + (-62)):

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 item 10 was meant differently, let me know and I’ll adjust.
