Let’s solve each subtraction problem step by step. Remember: subtract the ones place first, then the tens place. If the top digit in the ones place is smaller than the bottom one, we need to regroup (borrow) from the tens place.
---
Problem 1: 61 - 14
- Ones place: 1 - 4 → can’t do that! So borrow 1 ten from the 6 tens → now it’s 5 tens and 11 ones.
- 11 - 4 = 7
- Tens place: 5 - 1 = 4
→ Answer:
47
---
Problem 2: 70 - 47
- Ones place: 0 - 7 → can’t do that! Borrow 1 ten from the 7 tens → now it’s 6 tens and 10 ones.
- 10 - 7 = 3
- Tens place: 6 - 4 = 2
→ Answer:
23
---
Problem 3: 64 - 34
- Ones place: 4 - 4 = 0
- Tens place: 6 - 3 = 3
→ Answer:
30
*(No regrouping needed here!)*
---
Problem 4: 56 - 23
- Ones place: 6 - 3 = 3
- Tens place: 5 - 2 = 3
→ Answer:
33
*(No regrouping needed!)*
---
Problem 5: 88 - 12
- Ones place: 8 - 2 = 6
- Tens place: 8 - 1 = 7
→ Answer:
76
*(No regrouping needed!)*
---
Problem 6: 45 - 32
- Ones place: 5 - 2 = 3
- Tens place: 4 - 3 = 1
→ Answer:
13
*(No regrouping needed!)*
---
Problem 7: 66 - 20
- Ones place: 6 - 0 = 6
- Tens place: 6 - 2 = 4
→ Answer:
46
*(No regrouping needed!)*
---
Problem 8: 28 - 10
- Ones place: 8 - 0 = 8
- Tens place: 2 - 1 = 1
→ Answer:
18
*(No regrouping needed!)*
---
Problem 9: 67 - 26
- Ones place: 7 - 6 = 1
- Tens place: 6 - 2 = 4
→ Answer:
41
*(No regrouping needed!)*
