Worksheet for practicing multiplication and division of integers with 30 problems.

Let's solve each problem step by step, following the rules for multiplying and dividing integers:

🔷 Rules to Remember:

- Positive × Positive = Positive
- Negative × Negative = Positive
- Positive × Negative = Negative
- Negative ÷ Negative = Positive
- Positive ÷ Negative = Negative
- Zero times anything = 0

Now let’s go through each problem:

---

1) $ 28 \div 7 = 4 $
✔ (Positive ÷ Positive = Positive)

2) $ 5 \times (-5) = -25 $
✔ (Positive × Negative = Negative)

3) $ 1 \times 2 = 2 $
✔ (Positive × Positive = Positive)

4) $ 9 \div (-1) = -9 $
✔ (Positive ÷ Negative = Negative)

5) $ (-21) \div (-7) = 3 $
✔ (Negative ÷ Negative = Positive)

6) $ 0 \times 5 \times (-2) = 0 $
✔ (Any number multiplied by 0 is 0)

7) $ (-7) \times (-9) \times (-9) $
First: $ (-7) \times (-9) = 63 $ (Negative × Negative = Positive)
Then: $ 63 \times (-9) = -567 $ (Positive × Negative = Negative)
✔ Answer: -567

8) $ (-2) \times (-6) \times (-7) $
First: $ (-2) \times (-6) = 12 $
Then: $ 12 \times (-7) = -84 $
✔ Answer: -84

9) $ 9 \times (-10) = -90 $
✔ (Positive × Negative = Negative)

10) $ 6 \div 6 = 1 $
✔ (Positive ÷ Positive = Positive)

11) $ (-81) \div (-9) = 9 $
✔ (Negative ÷ Negative = Positive)

12) $ (-7) \times 3 \times (-6) $
First: $ (-7) \times 3 = -21 $
Then: $ -21 \times (-6) = 126 $
✔ Answer: 126

13) $ (-3) \times 4 \times (-4) $
First: $ (-3) \times 4 = -12 $
Then: $ -12 \times (-4) = 48 $
✔ Answer: 48

14) $ (-6) \times 7 \times (-6) $
First: $ (-6) \times 7 = -42 $
Then: $ -42 \times (-6) = 252 $
✔ Answer: 252

15) $ 9 \times (-9) \times (-9) $
First: $ 9 \times (-9) = -81 $
Then: $ -81 \times (-9) = 729 $
✔ Answer: 729

16) $ (-20) \div 2 = -10 $
✔ (Negative ÷ Positive = Negative)

17) $ (-9) \times 7 \times (-7) $
First: $ (-9) \times 7 = -63 $
Then: $ -63 \times (-7) = 441 $
✔ Answer: 441

18) $ 7 \times 2 = 14 $
✔ (Positive × Positive = Positive)

19) $ 4 \div 1 = 4 $
✔ (Positive ÷ Positive = Positive)

20) $ 5 \times 5 \times (-7) $
First: $ 5 \times 5 = 25 $
Then: $ 25 \times (-7) = -175 $
✔ Answer: -175

21) $ (-16) \div 4 = -4 $
✔ (Negative ÷ Positive = Negative)

22) $ (-5) \times 4 = -20 $
✔ (Negative × Positive = Negative)

23) $ (-12) \div (-6) = 2 $
✔ (Negative ÷ Negative = Positive)

24) $ (-12) \div (-3) = 4 $
✔ (Negative ÷ Negative = Positive)

25) $ (-2) \div (-2) = 1 $
✔ (Negative ÷ Negative = Positive)

26) $ 5 \times 4 = 20 $
✔ (Positive × Positive = Positive)

27) $ (-9) \times 4 = -36 $
✔ (Negative × Positive = Negative)

28) $ (-2) \times (-3) = 6 $
✔ (Negative × Negative = Positive)

29) $ 10 \times (-3) \times (-7) $
First: $ 10 \times (-3) = -30 $
Then: $ -30 \times (-7) = 210 $
✔ Answer: 210

30) $ (-6) \times (-6) = 36 $
✔ (Negative × Negative = Positive)
