Let's solve each of the problems step by step, applying the rules for
multiplying and dividing integers.
🔷 Rules to Remember:
1.
Positive × Positive = Positive
2.
Negative × Negative = Positive
3.
Positive × Negative = Negative
4.
Negative ÷ Negative = Positive
5.
Positive ÷ Negative = Negative
6.
Zero multiplied by any number = 0

Now let’s go through each problem:
---
1) $ 28 \div 7 = 4 $
2) $ 5 \times (-5) = -25 $
3) $ 1 \times 2 = 2 $
4) $ 9 \div (-1) = -9 $
5) $ (-21) \div (-7) = 3 $
(Negative ÷ Negative = Positive)
6) $ 0 \times 5 \times (-2) = 0 $
(Any number times zero is zero)
7) $ (-7) \times (-9) \times (-9) $
First: $ (-7) \times (-9) = 63 $
Then: $ 63 \times (-9) = -567 $
→ Result:
-567
8) $ (-2) \times (-6) \times (-7) $
First: $ (-2) \times (-6) = 12 $
Then: $ 12 \times (-7) = -84 $
→ Result:
-84
9) $ 9 \times (-10) = -90 $
10) $ 6 \div 6 = 1 $
11) $ (-81) \div (-9) = 9 $
(Negative ÷ Negative = Positive)
12) $ (-7) \times 3 \times (-6) $
First: $ (-7) \times 3 = -21 $
Then: $ -21 \times (-6) = 126 $
→ Result:
126
13) $ (-3) \times 4 \times (-4) $
First: $ (-3) \times 4 = -12 $
Then: $ -12 \times (-4) = 48 $
→ Result:
48
14) $ (-6) \times 7 \times (-6) $
First: $ (-6) \times 7 = -42 $
Then: $ -42 \times (-6) = 252 $
→ Result:
252
15) $ 9 \times (-9) \times (-9) $
First: $ 9 \times (-9) = -81 $
Then: $ -81 \times (-9) = 729 $
→ Result:
729
16) $ (-20) \div 2 = -10 $
17) $ (-9) \times 7 \times (-7) $
First: $ (-9) \times 7 = -63 $
Then: $ -63 \times (-7) = 441 $
→ Result:
441
18) $ 7 \times 2 = 14 $
19) $ 4 \div 1 = 4 $
20) $ 5 \times 5 \times (-7) $
First: $ 5 \times 5 = 25 $
Then: $ 25 \times (-7) = -175 $
→ Result:
-175
21) $ (-16) \div 4 = -4 $
22) $ (-5) \times 4 = -20 $
23) $ (-12) \div (-6) = 2 $
(Negative ÷ Negative = Positive)
24) $ (-12) \div (-3) = 4 $
25) $ (-2) \div (-2) = 1 $
26) $ 5 \times 4 = 20 $
27) $ (-9) \times 4 = -36 $
28) $ (-2) \times (-3) = 6 $
(Negative × Negative = Positive)
29) $ 10 \times (-3) \times (-7) $
First: $ 10 \times (-3) = -30 $
Then: $ -30 \times (-7) = 210 $
→ Result:
210
30) $ (-6) \times (-6) = 36 $
(Negative × Negative = Positive)
