Let’s solve each multiplication problem one by one. We’ll go row by row, left to right.
---
First Row:
1. 7 × 4 = ?
Think: 7 + 7 + 7 + 7 = 28 →
28
2. 6 × 3 = ?
Think: 6 + 6 + 6 = 18 →
18
3. 2 × 5 = ?
Think: 2 + 2 + 2 + 2 + 2 = 10 →
10
4. 3 × 7 = ?
Same as 7 × 3 = 21 →
21
---
Second Row:
5. 8 × 8 = ?
Think: 8 groups of 8 → 8, 16, 24, 32, 40, 48, 56, 64 →
64
6. 9 × 2 = ?
Double 9 → 18 →
18
7. 7 × 2 = ?
Double 7 → 14 →
14
8. 8 × 3 = ?
8 + 8 + 8 = 24 →
24
---
Third Row:
9. 9 × 5 = ?
Half of 9 × 10 (which is 90) → 45 →
45
10. 5 × 3 = ?
5 + 5 + 5 = 15 →
15
11. 7 × 6 = ?
Think: 7 × 5 = 35, plus one more 7 → 35 + 7 = 42 →
42
12. 5 × 7 = ?
Same as 7 × 5 = 35 →
35
---
Fourth Row:
13. 9 × 9 = ?
9 × 10 = 90, minus 9 → 81 →
81
14. 4 × 9 = ?
4 × 10 = 40, minus 4 → 36 →
36
15. 3 × 3 = ?
3 + 3 + 3 = 9 →
9
16. 6 × 6 = ?
6 + 6 + 6 + 6 + 6 + 6 = 36 →
36
---
Fifth Row:
17. 8 × 4 = ?
8 + 8 + 8 + 8 = 32 →
32
18. 5 × 8 = ?
Half of 10 × 8 = 80 → 40 →
40
19. 3 × 9 = ?
3 × 10 = 30, minus 3 → 27 →
27
20. 8 × 0 = ?
Anything times zero is zero →
0

Now let’s list all the answers in order, matching the layout:
Row 1: 28, 18, 10, 21
Row 2: 64, 18, 14, 24
Row 3: 45, 15, 42, 35
Row 4: 81, 36, 9, 36
Row 5: 32, 40, 27, 0
Final Answer:
28, 18, 10, 21, 64, 18, 14, 24, 45, 15, 42, 35, 81, 36, 9, 36, 32, 40, 27, 0
