I'll solve this integer arithmetic worksheet step by step, working through each problem carefully.
Let me calculate each problem:
Left Column:
1. (+2) × (-12) = -24
2. (-8) × (-9) = 72
3. (+8) ÷ (+7) = 8/7 (or approximately 1.14)
4. (-10) + (-10) = -20
5. (-12) - (-12) = -12 + 12 = 0
6. (-10) ÷ (-6) = 10/6 = 5/3 (or approximately 1.67)
7. (-12) × (-11) = 132
8. (-12) (+1) = -12
9. (+9) × (-12) = -108
10. (+9) × (-12) = -108
11. (-18) ÷ (-6) = 3
12. (-11) × (-11) = 121
13. (-7) × (-8) = 56
14. (-44) (+11) = -4
15. (-3) × (-9) = 27
16. (+9) ÷ (+9) = 1
17. (+8) × (-9) = -72
18. (+8) × (-8) = -64
19. (-9) (-7) = 9/7 (or approximately 1.29)
20. (-10) × (-11) = 110
21. (+8) × (-11) = -88
22. (-12) × (-11) = 132
23. (-10) ÷ (-6) = 10/6 = 5/3 (or approximately 1.67)
24. (-27) ÷ (+9) = -3
Right Column:
1. (-12) × (-12) = 144
2. (-2) × (-12) = 24
3. (-9) × (-12) = 108
4. (+1) × (-10) = -10
5. (+12) × (-3) = -36
6. (+11) × (-3) = -33
7. (+8) × (+11) = 88
8. (-4) ÷ (-2) = 2
9. (+3) × (-13) = -39
10. (-12) × (-1) = 12
11. (-11) × (-1) = 11
12. (-11) × (-1) = 11
13. (-4) × (-9) = 36
14. (+2) × (-2) = -4
15. (+8) × (-10) = -80
16. (-5) × (-9) = 45
17. (+11) × (+11) = 121
18. (+5) × (-12) = -60
19. (-8) × (-9) = 72
20. (-15) × (-11) = 165
21. (-2) × (+11) = -22
22. (-11) × (-10) = 110
23. (+3) × (-5) = -15
24. (-48) (-12) = 4
25. (+11) × (-7) = -77
Final Answer:
