3RD GRADE MATH - THREE DIGIT SUBTRACTION WITH REGROUPING — Steemit - Free Printable

You're working on a Three-Digit Subtraction With Regrouping worksheet. The goal is to subtract the bottom number from the top number in each problem, using regrouping (borrowing) when necessary.

The first problem is done as an example:

```
704
- 256
-----
448
```

✔ Explanation of Example:
- Ones place: 4 – 6 → Can’t do that, so borrow 1 from tens. But tens digit is 0, so we must go to hundreds.
- Borrow 1 from 7 (hundreds) → becomes 6; the 0 (tens) becomes 10.
- Now borrow 1 from tens (10) → becomes 9; ones become 14.
- 14 – 6 = 8
- Tens place: 9 – 5 = 4
- Hundreds place: 6 – 2 = 4
→ Answer: 448

Now let’s solve all the remaining problems step by step.

Problem 1: 341 – 163

```
341
- 163

```

- Ones: 1 – 3 → borrow → 11 – 3 = 8 (tens becomes 3)
- Tens: 3 – 6 → borrow → 13 – 6 = 7 (hundreds becomes 2)
- Hundreds: 2 – 1 = 1

✔ Answer: 178

Problem 2: 635 – 247

```
635
- 247
-----
```

- 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

```
607
- 379
-----
```

- Ones: 7 – 9 → borrow → 17 – 9 = 8 (tens is 0, so borrow from hundreds)
- Hundreds: 6 → 5, tens: 0 → 10, then borrow 1 for ones → tens becomes 9
- Tens: 9 – 7 = 2
- Hundreds: 5 – 3 = 2

✔ Answer: 228

Problem 4: 803 – 456

```
803
- 456
-----
```

- Ones: 3 – 6 → borrow → 13 – 6 = 7 (tens is 0 → borrow from hundreds)
- Hundreds: 8 → 7, tens: 0 → 10 → then borrow 1 → tens becomes 9
- Tens: 9 – 5 = 4
- Hundreds: 7 – 4 = 3

✔ Answer: 347

Problem 5: 904 – 495

```
904
- 495
-----
```

- Ones: 4 – 5 → borrow → 14 – 5 = 9 (tens is 0 → borrow from hundreds)
- Hundreds: 9 → 8, tens: 0 → 10 → borrow 1 → tens becomes 9
- Tens: 9 – 9 = 0
- Hundreds: 8 – 4 = 4

✔ Answer: 409

📌 Tip: Always start from the ones place, and if the top digit is smaller than the bottom, regroup (borrow) from the next higher place value — even if you have to go through zeros!
