Multiplication Problems:

1. $ 4 \times 4 = 16 $

2. $ -8 \times (-4) = +32 $
→ Negative × Negative = Positive

3. $ -12 \times (-8) = +96 $
→ Negative × Negative = Positive

4. $ -7 \times (+8) = -56 $
→ Negative × Positive = Negative

5. $ 9 \times 7 = 63 $

6. $ 13 \times (-6) = -78 $
→ Positive × Negative = Negative

7. $ 10 \times 11 = 110 $

8. $ 40 \times (-8) = -320 $
→ Positive × Negative = Negative

9. $ -9 \times (-8) = +72 $
→ Negative × Negative = Positive

10. $ 7 \times (-14) = -98 $
→ Positive × Negative = Negative

11. $ -12 \times (+12) = -144 $
→ Negative × Positive = Negative

12. $ 16 \times (-3) = -48 $
→ Positive × Negative = Negative

13. $ 5 \times (-6) = -30 $

14. $ -14 \times (-6) = +84 $
→ Negative × Negative = Positive

15. $ -12 \times (-9) = +108 $
→ Negative × Negative = Positive

16. $ 6 \times (-9) \times (10) $
First: $ 6 \times (-9) = -54 $
Then: $ -54 \times 10 = -540 $
→ Final answer: -540

Division Problems:

17. $ 15 \div 3 = 5 $

18. $ -20 \div 4 = -5 $
→ Negative ÷ Positive = Negative

19. $ \frac{-150}{25} = -6 $
→ Negative ÷ Positive = Negative

20. $ 122 \div 2 = 61 $

21. $ -72 \div (-12) = +6 $
→ Negative ÷ Negative = Positive

22. $ -64 \div 4 = -16 $
→ Negative ÷ Positive = Negative

23. $ 39 \div 3 = 13 $

24. $ 60 \div 5 = 12 $

25. $ 28 \div 7 = 4 $

26. $ -88 \div (-8) = +11 $
→ Negative ÷ Negative = Positive

27. $ -48 \div 3 = -16 $
→ Negative ÷ Positive = Negative

Mixed Operations (Order matters):

27. $ 14 \times (-4) \div (-2) $
Step 1: $ 14 \times (-4) = -56 $
Step 2: $ -56 \div (-2) = +28 $
→ Answer: 28

28. $ -15 \times (-5) \times 3 $
Step 1: $ -15 \times (-5) = +75 $
Step 2: $ 75 \times 3 = 225 $
→ Answer: 225

29. $ 121 \div (-11) \times 14 $
Step 1: $ 121 \div (-11) = -11 $
Step 2: $ -11 \times 14 = -154 $
→ Answer: -154

30. $ -240 \div 60 \times (-3) $
Step 1: $ -240 \div 60 = -4 $
Step 2: $ -4 \times (-3) = +12 $
→ Answer: 12
