Let me solve all the subtraction problems on this worksheet step by step.
Left column:
1. 20 - 3 = 17 ✓ (already filled)
2. 8 - 7 = 1, but shows 2 with "Try again!" — correct answer is 1
3. 2 - 1 = 1 ✓ (already filled)
4. 18 - 7 = 11
5. 1 - 1 = 0
6. 7 - 4 = 3
7. 8 - 8 = 0
8. 11 - 6 = 5
9. 10 - 8 = 2
10. 4 - 3 = 1
Right column:
1. 7 - 1 = 6
2. 10 - 10 = 0
3. 6 - 2 = 4
4. 10 - 5 = 5
5. 20 - 18 = 2
6. 2 - 1 = 1
7. 17 - 5 = 12
8. 12 - 12 = 0
9. 7 - 5 = 2
10. 2 - 2 = 0
Let me verify each calculation carefully:
Left side:
- 20 - 3 = 17 ✓
- 8 - 7 = 1 (the sheet shows 2 which is wrong)
- 2 - 1 = 1 ✓
- 18 - 7 = 11 ✓
- 1 - 1 = 0 ✓
- 7 - 4 = 3 ✓
- 8 - 8 = 0 ✓
- 11 - 6 = 5 ✓
- 10 - 8 = 2 ✓
- 4 - 3 = 1 ✓
Right side:
- 7 - 1 = 6 ✓
- 10 - 10 = 0 ✓
- 6 - 2 = 4 ✓
- 10 - 5 = 5 ✓
- 20 - 18 = 2 ✓
- 2 - 1 = 1 ✓
- 17 - 5 = 12 ✓
- 12 - 12 = 0 ✓
- 7 - 5 = 2 ✓
- 2 - 2 = 0 ✓
All calculations verified. Now I'll present the final answers in a clear format.
