1. 529 - 283
Start from the right:
- Ones place: 9 - 3 = 6
- Tens place: 2 - 8 → can’t do, so borrow from hundreds.
- 5 becomes 4, 2 becomes 12 → 12 - 8 = 4
- Hundreds place: 4 - 2 = 2
→
529 - 283 = 246
Check: 246 + 283 = 529
✔

2. 678 - 131
Ones: 8 - 1 = 7
Tens: 7 - 3 = 4
Hundreds: 6 - 1 = 5
→
678 - 131 = 547
Check: 547 + 131 = 678
✔
---
3. 467 - 245
Ones: 7 - 5 = 2
Tens: 6 - 4 = 2
Hundreds: 4 - 2 = 2
→
467 - 245 = 222
Check: 222 + 245 = 467
✔

4. 615 - 450
Ones: 5 - 0 = 5
Tens: 1 - 5 → can’t do, borrow from hundreds.
- 6 becomes 5, 1 becomes 11 → 11 - 5 = 6
Hundreds: 5 - 4 = 1
→
615 - 450 = 165
Check: 165 + 450 = 615
✔

5. 526 - 294
Ones: 6 - 4 = 2
Tens: 2 - 9 → can’t do, borrow from hundreds.
- 5 becomes 4, 2 becomes 12 → 12 - 9 = 3
Hundreds: 4 - 2 = 2
→
526 - 294 = 232
Check: 232 + 294 = 526
✔
---
