Three Digit Subtraction With Regrouping Worksheet - 2, with the first problem solved as an example.

Absolutely! Let’s solve each of the Three-Digit Subtraction With Regrouping problems step by step. The first one is already solved as an example:

---

✔ Example: 704 – 256 = 448

We’ll follow the same regrouping (borrowing) method for all others.

## 🔢 PROBLEM 1: 341 – 163

Step-by-step:

```
3 4 1
- 1 6 3
--------
```

- Ones place: 1 – 3 → Can’t do, so borrow from tens.
- Tens digit is 4 → becomes 3; ones becomes 11.
- 11 – 3 = 8

- Tens place: 3 – 6 → Can’t do, borrow from hundreds.
- Hundreds digit is 3 → becomes 2; tens becomes 13.
- 13 – 6 = 7

- Hundreds place: 2 – 1 = 1

✔ Answer: 178

## 🔢 PROBLEM 2: 635 – 247

```
6 3 5
- 2 4 7
--------
```

- Ones: 5 – 7 → borrow → 15 – 7 = 8 (tens becomes 2)
- Tens: 2 – 4 → borrow → 12 – 4 = 8 (hundreds becomes 5)
- Hundreds: 5 – 2 = 3

✔ Answer: 388

## 🔢 PROBLEM 3: 607 – 379

```
6 0 7
- 3 7 9
--------
```

- Ones: 7 – 9 → borrow → 17 – 9 = 8 (tens becomes 9, since we borrowed from 0 → need to go to hundreds)
- Actually: 0 can’t lend, so borrow from 6 → hundreds becomes 5, tens becomes 10, then lend 1 to ones → tens becomes 9, ones becomes 17.
- Tens: 9 – 7 = 2
- Hundreds: 5 – 3 = 2

✔ Answer: 228

## 🔢 PROBLEM 4: 803 – 456

```
8 0 3
- 4 5 6
--------
```

- Ones: 3 – 6 → borrow → 13 – 6 = 7 (tens becomes 9 after borrowing from 0 → which borrows from 8)
- So: 8 → 7, 0 → 10 → then 10 → 9 after lending to ones.
- Tens: 9 – 5 = 4
- Hundreds: 7 – 4 = 3

✔ Answer: 347

---

## 🔢 PROBLEM 5: 904 – 495

```
9 0 4
- 4 9 5
--------
```

- Ones: 4 – 5 → borrow → 14 – 5 = 9 (tens becomes 9 after borrowing from 0 → which borrows from 9)
- 9 → 8, 0 → 10 → then 10 → 9 after lending.
- Tens: 9 – 9 = 0
- Hundreds: 8 – 4 = 4

✔ Answer: 409

## 🔢 PROBLEM 6: 510 – 373

```
5 1 0
- 3 7 3
--------
```

- Ones: 0 – 3 → borrow → 10 – 3 = 7 (tens becomes 0 after borrowing)
- Tens: 0 – 7 → borrow → 10 – 7 = 3 (hundreds becomes 4)
- Hundreds: 4 – 3 = 1

✔ Answer: 137

---

## 🔢 PROBLEM 7: 531 – 367

```
5 3 1
- 3 6 7
--------
```

- Ones: 1 – 7 → borrow → 11 – 7 = 4 (tens becomes 2)
- Tens: 2 – 6 → borrow → 12 – 6 = 6 (hundreds becomes 4)
- Hundreds: 4 – 3 = 1

✔ Answer: 164

## 🔢 PROBLEM 8: 962 – 389

```
9 6 2
- 3 8 9
--------
```

- Ones: 2 – 9 → borrow → 12 – 9 = 3 (tens becomes 5)
- Tens: 5 – 8 → borrow → 15 – 8 = 7 (hundreds becomes 8)
- Hundreds: 8 – 3 = 5

✔ Answer: 573

## 🔢 PROBLEM 9: 745 – 467

```
7 4 5
- 4 6 7
--------
```

- Ones: 5 – 7 → borrow → 15 – 7 = 8 (tens becomes 3)
- Tens: 3 – 6 → borrow → 13 – 6 = 7 (hundreds becomes 6)
- Hundreds: 6 – 4 = 2

✔ Answer: 278

## 🔢 PROBLEM 10: 823 – 645

```
8 2 3
- 6 4 5
--------
```

- Ones: 3 – 5 → borrow → 13 – 5 = 8 (tens becomes 1)
- Tens: 1 – 4 → borrow → 11 – 4 = 7 (hundreds becomes 7)
- Hundreds: 7 – 6 = 1

✔ Answer: 178

## 🔢 PROBLEM 11: 555 – 487

```
5 5 5
- 4 8 7
--------
```

- Ones: 5 – 7 → borrow → 15 – 7 = 8 (tens becomes 4)
- Tens: 4 – 8 → borrow → 14 – 8 = 6 (hundreds becomes 4)
- Hundreds: 4 – 4 = 0

✔ Answer: 68

*(Note: Leading zero not written — so just 68)*
