3 Digit Subtraction with Regrouping Digital Bundle - Marvel Math - Free Printable

The image shows a digital activity focused on 3-Digit Subtraction with Regrouping. Below, I will solve the subtraction problems presented in the image and explain the process step by step.

---

Problem 1: \( 547 - 299 \)

#### Step-by-Step Solution:
1. Align the numbers by place value:
```
547
- 299
```

2. Subtract the ones place:
- You need to subtract \( 7 - 9 \). Since 7 is less than 9, you must regroup.
- Borrow 1 from the tens place (4 becomes 3), and the 7 in the ones place becomes 17.
- Now, \( 17 - 9 = 8 \).

3. Subtract the tens place:
- After borrowing, the tens place is now 3. You need to subtract \( 3 - 9 \).
- Since 3 is less than 9, you must regroup again.
- Borrow 1 from the hundreds place (5 becomes 4), and the 3 in the tens place becomes 13.
- Now, \( 13 - 9 = 4 \).

4. Subtract the hundreds place:
- After borrowing, the hundreds place is now 4. Subtract \( 4 - 2 = 2 \).

5. Combine the results:
```
547
- 299
------
248
```

So, \( 547 - 299 = 248 \).

Problem 2: \( 500 - 319 \)

#### Step-by-Step Solution:
1. Align the numbers by place value:
```
500
- 319
```

2. Subtract the ones place:
- You need to subtract \( 0 - 9 \). Since 0 is less than 9, you must regroup.
- Borrow 1 from the tens place (0 becomes 10), and the 0 in the ones place becomes 10.
- Now, \( 10 - 9 = 1 \).

3. Subtract the tens place:
- After borrowing, the tens place is now 0 (since we borrowed from it earlier). You need to subtract \( 0 - 1 \).
- Since 0 is less than 1, you must regroup again.
- Borrow 1 from the hundreds place (5 becomes 4), and the 0 in the tens place becomes 10.
- Now, \( 10 - 1 = 9 \).

4. Subtract the hundreds place:
- After borrowing, the hundreds place is now 4. Subtract \( 4 - 3 = 1 \).

5. Combine the results:
```
500
- 319
------
181
```

So, \( 500 - 319 = 181 \).

Problem 3: \( 300 - 173 \)

#### Step-by-Step Solution:
1. Align the numbers by place value:
```
300
- 173
```

2. Subtract the ones place:
- You need to subtract \( 0 - 3 \). Since 0 is less than 3, you must regroup.
- Borrow 1 from the tens place (0 becomes 10), and the 0 in the ones place becomes 10.
- Now, \( 10 - 3 = 7 \).

3. Subtract the tens place:
- After borrowing, the tens place is now 0 (since we borrowed from it earlier). You need to subtract \( 0 - 7 \).
- Since 0 is less than 7, you must regroup again.
- Borrow 1 from the hundreds place (3 becomes 2), and the 0 in the tens place becomes 10.
- Now, \( 10 - 7 = 3 \).

4. Subtract the hundreds place:
- After borrowing, the hundreds place is now 2. Subtract \( 2 - 1 = 1 \).

5. Combine the results:
```
300
- 173
------
127
```

So, \( 300 - 173 = 127 \).

Problem 4: \( 400 - 205 \)

#### Step-by-Step Solution:
1. Align the numbers by place value:
```
400
- 205
```

2. Subtract the ones place:
- You need to subtract \( 0 - 5 \). Since 0 is less than 5, you must regroup.
- Borrow 1 from the tens place (0 becomes 10), and the 0 in the ones place becomes 10.
- Now, \( 10 - 5 = 5 \).

3. Subtract the tens place:
- After borrowing, the tens place is now 0 (since we borrowed from it earlier). You need to subtract \( 0 - 0 = 0 \).

4. Subtract the hundreds place:
- Subtract \( 4 - 2 = 2 \).

5. Combine the results:
```
400
- 205
------
195
```

So, \( 400 - 205 = 195 \).

Final Answers:

1. \( 547 - 299 = \boxed{248} \)
2. \( 500 - 319 = \boxed{181} \)
3. \( 300 - 173 = \boxed{127} \)
4. \( 400 - 205 = \boxed{195} \)
