Let’s solve each subtraction problem step by step. We’ll subtract the bottom number from the top number, column by column (ones, then tens, then hundreds). If we can’t subtract a bigger number from a smaller one in a column, we’ll borrow from the next column to the left.

1. 557 - 349
- Ones: 7 - 9 → Can’t do! Borrow 1 from tens → 17 - 9 =
8
- Tens: Now 4 (since we borrowed) - 4 =
0
- Hundreds: 5 - 3 =
2
→ Answer:
208

2. 825 - 449
- Ones: 5 - 9 → Can’t do! Borrow → 15 - 9 =
6
- Tens: Now 1 (borrowed) - 4 → Can’t do! Borrow from hundreds → 11 - 4 =
7
- Hundreds: Now 7 (borrowed) - 4 =
3
→ Answer:
376
