Let’s solve each problem one by one. We’ll use the rules for multiplying and dividing integers:
- Positive × Positive = Positive
- Negative × Negative = Positive
- Positive × Negative = Negative
- Same for division: same signs → positive, different signs → negative
- Any number multiplied by 0 is 0
- Order doesn’t matter in multiplication (you can multiply left to right or group them)

1) 28 ÷ 7 =
4
→ Both positive → answer positive.
2) 5 × (-5) =
-25
→ Positive × Negative = Negative.
3) 1 × 2 =
2
→ Simple multiplication.
4) 9 ÷ (-1) =
-9
→ Positive ÷ Negative = Negative.
5) (-21) ÷ (-7) =
3
→ Negative ÷ Negative = Positive. 21 ÷ 7 = 3.
6) 0 × 5 × (-2) =
0
→ Anything times 0 is 0.
7) (-7) × (-9) × (-9)
First: (-7) × (-9) = 63 (negative × negative = positive)
Then: 63 × (-9) = -567 (positive × negative = negative)
→ Answer:
-567
8) (-2) × (-6) × (-7)
First: (-2) × (-6) = 12
Then: 12 × (-7) = -84
→ Answer:
-84
9) 9 × (-10) =
-90
10) 6 ÷ 6 =
1
11) (-81) ÷ (-9) =
9
→ Negative ÷ Negative = Positive. 81 ÷ 9 = 9.
12) (-7) × 3 × (-6)
First: (-7) × 3 = -21
Then: -21 × (-6) = 126 (negative × negative = positive)
→ Answer:
126
13) (-3) × 4 × (-4)
First: (-3) × 4 = -12
Then: -12 × (-4) = 48
→ Answer:
48
14) (-6) × 7 × (-6)
First: (-6) × 7 = -42
Then: -42 × (-6) = 252
→ Answer:
252
15) 9 × (-9) × (-9)
First: 9 × (-9) = -81
Then: -81 × (-9) = 729
→ Answer:
729
16) (-20) ÷ 2 =
-10
17) (-9) × 7 × (-7)
First: (-9) × 7 = -63
Then: -63 × (-7) = 441
→ Answer:
441
18) 7 × 2 =
14
19) 4 ÷ 1 =
4
20) 5 × 5 × (-7)
First: 5 × 5 = 25
Then: 25 × (-7) = -175
→ Answer:
-175
21) (-16) ÷ 4 =
-4
22) (-5) × 4 =
-20
23) (-12) ÷ (-6) =
2
24) (-12) ÷ (-3) =
4
25) (-2) ÷ (-2) =
1
26) 5 × 4 =
20
27) (-9) × 4 =
-36
28) (-2) × (-3) =
6
29) 10 × (-3) × (-7)
First: 10 × (-3) = -30
Then: -30 × (-7) = 210
→ Answer:
210
30) (-6) × (-6) =
36
