Problem: Solve the three-digit subtraction problems with regrouping from the worksheet.

The worksheet contains multiple subtraction problems, and we need to solve each one step by step. Let's go through each problem systematically.

---

#### Row 1:
1. 704 - 256
- Solution is already provided: 448

2. 341 - 163
- Subtract digit by digit:
- Ones place: \(1 - 3\) → Borrow 1 from tens place (4 becomes 3), so \(11 - 3 = 8\).
- Tens place: \(3 - 6\) → Borrow 1 from hundreds place (3 becomes 2), so \(13 - 6 = 7\).
- Hundreds place: \(2 - 1 = 1\).
- Result: 178

3. 635 - 247
- Subtract digit by digit:
- Ones place: \(5 - 7\) → Borrow 1 from tens place (3 becomes 2), so \(15 - 7 = 8\).
- Tens place: \(2 - 4\) → Borrow 1 from hundreds place (6 becomes 5), so \(12 - 4 = 8\).
- Hundreds place: \(5 - 2 = 3\).
- Result: 388

#### Row 2:
4. 607 - 379
- Subtract digit by digit:
- Ones place: \(7 - 9\) → Borrow 1 from tens place (0 becomes 9), so \(17 - 9 = 8\).
- Tens place: \(9 - 7 = 2\).
- Hundreds place: \(5 - 3 = 2\).
- Result: 228

5. 803 - 456
- Subtract digit by digit:
- Ones place: \(3 - 6\) → Borrow 1 from tens place (0 becomes 9), so \(13 - 6 = 7\).
- Tens place: \(9 - 5 = 4\).
- Hundreds place: \(7 - 4 = 3\).
- Result: 347

6. 904 - 495
- Subtract digit by digit:
- Ones place: \(4 - 5\) → Borrow 1 from tens place (0 becomes 9), so \(14 - 5 = 9\).
- Tens place: \(9 - 9 = 0\).
- Hundreds place: \(8 - 4 = 4\).
- Result: 409
