Printable math worksheet focused on 2-digit subtraction with regrouping, ideal for elementary students.

The task involves solving a series of 2-digit subtraction problems with regrouping. Let's solve each problem step by step.

Problem 1: \( 76 - 38 \)

1. Subtract the ones place: \( 6 - 8 \). Since 6 is less than 8, we need to regroup.
- Borrow 1 from the tens place (7 becomes 6).
- The ones place now becomes \( 16 - 8 = 8 \).
2. Subtract the tens place: \( 6 - 3 = 3 \).
3. Result: \( 76 - 38 = 38 \).

Problem 2: \( 63 - 27 \)

1. Subtract the ones place: \( 3 - 7 \). Since 3 is less than 7, we need to regroup.
- Borrow 1 from the tens place (6 becomes 5).
- The ones place now becomes \( 13 - 7 = 6 \).
2. Subtract the tens place: \( 5 - 2 = 3 \).
3. Result: \( 63 - 27 = 36 \).

Problem 3: \( 58 - 29 \)

1. Subtract the ones place: \( 8 - 9 \). Since 8 is less than 9, we need to regroup.
- Borrow 1 from the tens place (5 becomes 4).
- The ones place now becomes \( 18 - 9 = 9 \).
2. Subtract the tens place: \( 4 - 2 = 2 \).
3. Result: \( 58 - 29 = 29 \).

Problem 4: \( 68 - 39 \)

1. Subtract the ones place: \( 8 - 9 \). Since 8 is less than 9, we need to regroup.
- Borrow 1 from the tens place (6 becomes 5).
- The ones place now becomes \( 18 - 9 = 9 \).
2. Subtract the tens place: \( 5 - 3 = 2 \).
3. Result: \( 68 - 39 = 29 \).

Problem 5: \( 44 - 35 \)

1. Subtract the ones place: \( 4 - 5 \). Since 4 is less than 5, we need to regroup.
- Borrow 1 from the tens place (4 becomes 3).
- The ones place now becomes \( 14 - 5 = 9 \).
2. Subtract the tens place: \( 3 - 3 = 0 \).
3. Result: \( 44 - 35 = 9 \).

Problem 6: \( 80 - 47 \)

1. Subtract the ones place: \( 0 - 7 \). Since 0 is less than 7, we need to regroup.
- Borrow 1 from the tens place (8 becomes 7).
- The ones place now becomes \( 10 - 7 = 3 \).
2. Subtract the tens place: \( 7 - 4 = 3 \).
3. Result: \( 80 - 47 = 33 \).

Problem 7: \( 83 - 57 \)

1. Subtract the ones place: \( 3 - 7 \). Since 3 is less than 7, we need to regroup.
- Borrow 1 from the tens place (8 becomes 7).
- The ones place now becomes \( 13 - 7 = 6 \).
2. Subtract the tens place: \( 7 - 5 = 2 \).
3. Result: \( 83 - 57 = 26 \).

Problem 8: \( 65 - 37 \)

1. Subtract the ones place: \( 5 - 7 \). Since 5 is less than 7, we need to regroup.
- Borrow 1 from the tens place (6 becomes 5).
- The ones place now becomes \( 15 - 7 = 8 \).
2. Subtract the tens place: \( 5 - 3 = 2 \).
3. Result: \( 65 - 37 = 28 \).

Problem 9: \( 58 - 49 \)

1. Subtract the ones place: \( 8 - 9 \). Since 8 is less than 9, we need to regroup.
- Borrow 1 from the tens place (5 becomes 4).
- The ones place now becomes \( 18 - 9 = 9 \).
2. Subtract the tens place: \( 4 - 4 = 0 \).
3. Result: \( 58 - 49 = 9 \).

Problem 10: \( 45 - 38 \)

1. Subtract the ones place: \( 5 - 8 \). Since 5 is less than 8, we need to regroup.
- Borrow 1 from the tens place (4 becomes 3).
- The ones place now becomes \( 15 - 8 = 7 \).
2. Subtract the tens place: \( 3 - 3 = 0 \).
3. Result: \( 45 - 38 = 7 \).

Problem 11: \( 30 - 18 \)

1. Subtract the ones place: \( 0 - 8 \). Since 0 is less than 8, we need to regroup.
- Borrow 1 from the tens place (3 becomes 2).
- The ones place now becomes \( 10 - 8 = 2 \).
2. Subtract the tens place: \( 2 - 1 = 1 \).
3. Result: \( 30 - 18 = 12 \).

Problem 12: \( 91 - 35 \)

1. Subtract the ones place: \( 1 - 5 \). Since 1 is less than 5, we need to regroup.
- Borrow 1 from the tens place (9 becomes 8).
- The ones place now becomes \( 11 - 5 = 6 \).
2. Subtract the tens place: \( 8 - 3 = 5 \).
3. Result: \( 91 - 35 = 56 \).

Final Answers:

\[
\boxed{
\begin{array}{ccc}
76 - 38 = 38 & 63 - 27 = 36 & 58 - 29 = 29 \\
