Let’s solve each subtraction problem step by step. We’ll subtract the bottom number from the top number, column by column (ones, tens, hundreds), and borrow if needed.
---
1. 494 - 315
- Ones: 4 - 5 → can’t do, so borrow from tens.
Tens become 8, ones become 14.
14 - 5 =
9
- Tens: 8 - 1 =
7
- Hundreds: 4 - 3 =
1
→
179
---
2. 567 - 328
- Ones: 7 - 8 → borrow. Tens become 5, ones become 17.
17 - 8 =
9
- Tens: 5 - 2 =
3
- Hundreds: 5 - 3 =
2
→
239
---
3. 952 - 648
- Ones: 2 - 8 → borrow. Tens become 4, ones become 12.
12 - 8 =
4
- Tens: 4 - 4 =
0
- Hundreds: 9 - 6 =
3
→
304
---
4. 345 - 256
- Ones: 5 - 6 → borrow. Tens become 3, ones become 15.
15 - 6 =
9
- Tens: 3 - 5 → borrow. Hundreds become 2, tens become 13.
13 - 5 =
8
- Hundreds: 2 - 2 =
0
→
89
---
5. 792 - 537
- Ones: 2 - 7 → borrow. Tens become 8, ones become 12.
12 - 7 =
5
- Tens: 8 - 3 =
5
- Hundreds: 7 - 5 =
2
→
255
---
6. 922 - 462
- Ones: 2 - 2 =
0
- Tens: 2 - 6 → borrow. Hundreds become 8, tens become 12.
12 - 6 =
6
- Hundreds: 8 - 4 =
4
→
460
---
7. 853 - 342
- Ones: 3 - 2 =
1
- Tens: 5 - 4 =
1
- Hundreds: 8 - 3 =
5
→
511
---
8. 719 - 462
- Ones: 9 - 2 =
7
- Tens: 1 - 6 → borrow. Hundreds become 6, tens become 11.
11 - 6 =
5
- Hundreds: 6 - 4 =
2
→
257
---
9. 503 - 224
- Ones: 3 - 4 → borrow. But tens is 0, so we must borrow from hundreds first.
Hundreds: 5 becomes 4. Tens: 0 becomes 10. Then borrow 1 for ones → tens become 9, ones become 13.
13 - 4 =
9
- Tens: 9 - 2 =
7
- Hundreds: 4 - 2 =
2
→
279
---
10. 685 - 473
- Ones: 5 - 3 =
2
- Tens: 8 - 7 =
1
- Hundreds: 6 - 4 =
2
→
212
---
11. 956 - 728
- Ones: 6 - 8 → borrow. Tens become 4, ones become 16.
16 - 8 =
8
- Tens: 4 - 2 =
2
- Hundreds: 9 - 7 =
2
→
228
---
12. 637 - 408
- Ones: 7 - 8 → borrow. Tens become 2, ones become 17.
17 - 8 =
9
- Tens: 2 - 0 =
2
- Hundreds: 6 - 4 =
2
→
229
