The worksheet asks us to subtract the following sums using the method of regrouping (borrowing). Let's solve each problem step by step.

---

#### 1. \( 9173 - 5268 \)

```
Th H T O
9 1 7 3
- 5 2 6 8
----------------
3 9 0 5
```

Explanation:
- Ones place: \( 3 - 8 \) → Borrow 1 from the tens place. Now, \( 13 - 8 = 5 \).
- Tens place: After borrowing, \( 6 - 6 = 0 \).
- Hundreds place: \( 0 - 2 \) → Borrow 1 from the thousands place. Now, \( 10 - 2 = 8 \).
- Thousands place: After borrowing, \( 8 - 5 = 3 \).

Answer: \( 3905 \)
