Let’s solve each subtraction problem step by step. We’ll go row by row, left to right.
---
Row 1:
1. 1562 – 1357
Start from the right:
2 – 7 → can’t do, borrow → 12 – 7 = 5
5 (became 4) – 5 = -1? Wait — let’s do it properly:
Actually:
```
1562
- 1357
------
```
Ones: 2 < 7 → borrow from tens → 12 – 7 = 5
Tens: 6 became 5 → 5 – 5 = 0
Hundreds: 5 – 3 = 2
Thousands: 1 – 1 = 0
→ 205
Let me double-check: 1357 + 205 = 1562 ✔️
2. 9220 – 7885
```
9220
- 7885
------
```
Ones: 0 < 5 → borrow → 10 – 5 = 5
Tens: 2 became 1 → 1 < 8 → borrow → 11 – 8 = 3
Hundreds: 2 became 1 → 1 < 8 → borrow → 11 – 8 = 3

→ 1335
Check: 7885 + 1335 = 9220 ✔️
3. 2483 – 1750
Easy since no borrowing needed in most places:
3 – 0 = 3
8 – 5 = 3
4 – 7 → can’t → borrow → 14 – 7 = 7
2 became 1 → 1 – 1 = 0
→ 733
Check: 1750 + 733 = 2483 ✔️
