Let’s solve each subtraction problem step by step. We’ll go column by column (ones, tens, hundreds) and borrow if needed.
---
1. 557 - 349
- Ones: 7 - 9 → can’t do, so borrow from tens. Tens becomes 4, ones becomes 17. 17 - 9 = 8
- Tens: 4 - 4 = 0
- Hundreds: 5 - 3 = 2
→
208
---
2. 825 - 449
- Ones: 5 - 9 → borrow. Tens become 1, ones become 15. 15 - 9 = 6
- Tens: 1 - 4 → can’t do, borrow from hundreds. Hundreds become 7, tens become 11. 11 - 4 = 7
- Hundreds: 7 - 4 = 3
→
376

3. 638 - 428
- Ones: 8 - 8 = 0
- Tens: 3 - 2 = 1
- Hundreds: 6 - 4 = 2
→
210

4. 567 - 362
- Ones: 7 - 2 = 5
- Tens: 6 - 6 = 0
- Hundreds: 5 - 3 = 2
→
205

5. 956 - 225
- Ones: 6 - 5 = 1
- Tens: 5 - 2 = 3
- Hundreds: 9 - 2 = 7
→
731

6. 739 - 446
- Ones: 9 - 6 = 3
- Tens: 3 - 4 → borrow. Hundreds become 6, tens become 13. 13 - 4 = 9
- Hundreds: 6 - 4 = 2
→
293

7. 852 - 417
- Ones: 2 - 7 → borrow. Tens become 4, ones become 12. 12 - 7 = 5
- Tens: 4 - 1 = 3
- Hundreds: 8 - 4 = 4
→
435
---
8. 362 - 253
- Ones: 2 - 3 → borrow. Tens become 5, ones become 12. 12 - 3 = 9
- Tens: 5 - 5 = 0
- Hundreds: 3 - 2 = 1
→
109

9. 774 - 525
- Ones: 4 - 5 → borrow. Tens become 6, ones become 14. 14 - 5 = 9
- Tens: 6 - 2 = 4
- Hundreds: 7 - 5 = 2
→
249

10. 887 - 559
- Ones: 7 - 9 → borrow. Tens become 7, ones become 17. 17 - 9 = 8
- Tens: 7 - 5 = 2

11. 637 - 297
- Ones: 7 - 7 = 0
- Tens: 3 - 9 → borrow. Hundreds become 5, tens become 13. 13 - 9 = 4
- Hundreds: 5 - 2 = 3
→
340

12. 826 - 438
- Ones: 6 - 8 → borrow. Tens become 1, ones become 16. 16 - 8 = 8
- Tens: 1 - 3 → borrow. Hundreds become 7, tens become 11. 11 - 3 = 8
- Hundreds: 7 - 4 = 3
→
388
