- The ones place now becomes \( 12 - 4 = 8 \).
2. Subtract the tens place: \( 5 - 5 = 0 \).
3. Result: \( 62 - 54 = 8 \).

Problem 2: \( 76 - 37 \)

1. Subtract the ones place: \( 6 - 7 \). Since 6 is less than 7, we need to regroup.
- Borrow 1 from the tens place (7 becomes 6).
- The ones place now becomes \( 16 - 7 = 9 \).
2. Subtract the tens place: \( 6 - 3 = 3 \).
3. Result: \( 76 - 37 = 39 \).

Problem 3: \( 75 - 38 \)

1. Subtract the ones place: \( 5 - 8 \). Since 5 is less than 8, we need to regroup.
