Let’s solve each subtraction problem step by step. We’re doing “subtraction with regrouping,” which means sometimes we need to borrow from the next column when the top number is smaller than the bottom one.

Problem 1: 892 – 483
Start from the right (ones place):
- Ones: 2 – 3 → can’t do, so borrow from tens. Tens become 8, ones become 12. 12 – 3 = 9
- Tens: 8 – 8 = 0
- Hundreds: 8 – 4 = 4
→
409

Problem 2: 659 – 277
Ones: 9 – 7 = 2
Tens: 5 – 7 → can’t do, borrow from hundreds. Hundreds become 5, tens become 15. 15 – 7 = 8
Hundreds: 5 – 2 = 3
→
382
---
Problem 3: 952 – 386
Ones: 2 – 6 → borrow. Tens become 4, ones become 12. 12 – 6 = 6
Tens: 4 – 8 → borrow from hundreds. Hundreds become 8, tens become 14. 14 – 8 = 6
Hundreds: 8 – 3 = 5
→
566
---
Problem 4: 529 – 343
Ones: 9 – 3 = 6
Tens: 2 – 4 → borrow. Hundreds become 4, tens become 12. 12 – 4 = 8
Hundreds: 4 – 3 = 1
→
186
---
Problem 5: 792 – 373
Ones: 2 – 3 → borrow. Tens become 8, ones become 12. 12 – 3 = 9
Tens: 8 – 7 = 1
Hundreds: 7 – 3 = 4
→
419
---
Problem 6: 563 – 483
Ones: 3 – 3 = 0
Tens: 6 – 8 → borrow. Hundreds become 4, tens become 16. 16 – 8 = 8
Hundreds: 4 – 4 = 0
→
80
---
Problem 7: 437 – 385
Ones: 7 – 5 = 2
Tens: 3 – 8 → borrow. Hundreds become 3, tens become 13. 13 – 8 = 5
Hundreds: 3 – 3 = 0
→
52
---
Problem 8: 455 – 262
Ones: 5 – 2 = 3
Tens: 5 – 6 → borrow. Hundreds become 3, tens become 15. 15 – 6 = 9
Hundreds: 3 – 2 = 1
→
193
---
Problem 9: 590 – 229
Ones: 0 – 9 → borrow. Tens become 8, ones become 10. 10 – 9 = 1
Tens: 8 – 2 = 6
Hundreds: 5 – 2 = 3
→
361
---
Problem 10: 656 – 438
Ones: 6 – 8 → borrow. Tens become 4, ones become 16. 16 – 8 = 8
Tens: 4 – 3 = 1
Hundreds: 6 – 4 = 2
→
218
---
Problem 11: 709 – 332
Ones: 9 – 2 = 7
Tens: 0 – 3 → borrow. Hundreds become 6, tens become 10. 10 – 3 = 7
Hundreds: 6 – 3 = 3
→
377

Final Answer:
409, 382, 566, 186, 419, 80, 52, 193, 361, 218, 377
