Let’s solve each multiplication problem step by step. We’ll do them one at a time and check our work carefully.

1. Dark Green: 52 × 85
Break it down:
- 50 × 85 = 4,250
- 2 × 85 = 170
- Add them: 4,250 + 170 =
4,420
✔ Check:
52 × 85
= (50 + 2) × 85
= 50×85 + 2×85
= 4,250 + 170 = 4,420 → Correct!

2. Light Green: 39 × 17
Break it down:
- 40 × 17 = 680
- But we used 40 instead of 39, so subtract 1 × 17 = 17
- 680 - 17 =
663
✔ Check:
39 × 17
= (40 - 1) × 17
= 680 - 17 = 663 → Correct!

3. Yellow: 25 × 61
Think: 25 × 60 = 1,500; then add 25 × 1 = 25 → 1,500 + 25 =
1,525
✔ Check:
25 × 61
= 25 × (60 + 1)
= 1,500 + 25 = 1,525 → Correct!

4. Red: 31 × 84
Break it down:
- 30 × 84 = 2,520
- 1 × 84 = 84
- Add: 2,520 + 84 =
2,604
✔ Check:
31 × 84
= (30 + 1) × 84
= 2,520 + 84 = 2,604 → Correct!
---
5. White: 65 × 48
Break it down:
- 65 × 50 = 3,250
- But we want 65 × 48, which is 2 less than 50 → subtract 65 × 2 = 130
- 3,250 - 130 =
3,120
✔ Check:
65 × 48
= 65 × (50 - 2)
= 3,250 - 130 = 3,120 → Correct!
