Let's solve each of these multiplication problems involving positive and negative integers. We'll go step by step, applying the rules for multiplying signed numbers:

Rules for Multiplying Signed Numbers:

1. Positive × Positive = Positive
2. Negative × Negative = Positive
3. Positive × Negative = Negative
4. Any number × 0 = 0

Now let’s solve each problem:

---

1) (+3) × (+7)
Same signs → Positive
= +21

2) (+7) × (-2)
Different signs → Negative
= -14

3) (+6) × (-2)
Different signs → Negative
= -12

4) (+7) × (+6)
Same signs → Positive
= +42

5) (-8) × (+6)
Different signs → Negative
= -48

6) (+7) × (+9)
Same signs → Positive
= +63

7) (+5) × (0)
Any number × 0 = 0
= 0

8) (-4) × (0)
Any number × 0 = 0
= 0

9) (-6) × (0)
Any number × 0 = 0
= 0

10) (0) × (+7)
Any number × 0 = 0
= 0

11) (+5) × (+4)
Same signs → Positive
= +20

12) (+7) × (+5)
Same signs → Positive
= +35

13) (+4) × (+2)
Same signs → Positive
= +8

14) (0) × (-3)
Any number × 0 = 0
= 0

15) (-1) × (+5)
Different signs → Negative
= -5

16) (0) × (+3)
Any number × 0 = 0
= 0

17) (-7) × (+4)
Different signs → Negative
= -28

18) (+4) × (+8)
Same signs → Positive
= +32

19) (0) × (-2)
Any number × 0 = 0
= 0

20) (+3) × (-5)
Different signs → Negative
= -15

✔ Explanation Summary:
We used the sign rules for multiplication:
- Same signs → positive
- Different signs → negative
- Any number times zero is zero.

These are fundamental concepts in integer arithmetic.
