Absolutely! Let’s solve each of the 15 subtraction problems step by step, using
regrouping (borrowing) where needed. The first problem is already solved as an example:
---
✔ Example:
675 – 328 = 347
- Ones place: 5 < 8 → borrow from tens → 15 – 8 = 7
- Tens place: 7 became 6 → 6 – 2 = 4
- Hundreds place: 6 – 3 = 3
→
Answer: 347

10. 933 – 626
- Ones: 3 < 6 → borrow → 13 – 6 = 7
- Tens: 3 became 2 → 2 – 2 = 0
- Hundreds: 9 – 6 = 3
✔ Answer: 307

11. 691 – 422
- Ones: 1 < 2 → borrow → 11 – 2 = 9
- Tens: 9 became 8 → 8 – 2 = 6
- Hundreds: 6 – 4 = 2
✔ Answer: 269

## 🔢 Row 5
12. 580 – 108
- Ones: 0 < 8 → borrow → 10 – 8 = 2
- Tens: 8 became 7 → 7 – 0 = 7
- Hundreds: 5 – 1 = 4
✔ Answer: 472
---
13. 252 – 247
- Ones: 2 < 7 → borrow → 12 – 7 = 5
- Tens: 5 became 4 → 4 – 4 = 0
- Hundreds: 2 – 2 = 0 → (we don’t write leading zero)
✔ Answer: 5
*(Note: This is a 1-digit answer, but correct!)*
---
14. 612 – 104
- Ones: 2 < 4 → borrow → 12 – 4 = 8
- Tens: 1 became 0 → 0 < 0? Wait — we need to borrow again!
→ Actually, since 0 – 0 = 0, no need to borrow further.
Wait — correction:
After borrowing for ones, tens digit is 0 (from 1). We subtract 0 → 0 – 0 = 0
Hundreds: 6 – 1 = 5
✔ Answer: 508
*(Double-check: 612 – 104 = 508 ✔️)*
