It looks like you've uploaded an image of a
completed 2-digit subtraction worksheet with answers. The title is:
"2 DIGIT SUBTRACTION SHEET 6 ANSWERS", and it's from
Math-Salamanders.com, aimed at
2nd-grade students.
Let me walk through the problem and explain how each subtraction was solved, using the standard
column subtraction method (also known as vertical subtraction). This includes borrowing when necessary.

🔢 Understanding the Process
In 2-digit subtraction:
- We subtract the
ones column first.
- Then the
tens column.
- If the top digit in the ones column is smaller than the bottom one, we
borrow 1 from the tens column.
Let’s go over a few examples to demonstrate:
---
✔ Example 1: 74 - 35
```
74
- 35
----
39
```
- Ones: 4 - 5 → can't do, so borrow 1 from 7 → becomes 14 - 5 =
9
- Tens: 6 (after borrowing) - 3 =
3
→ Result:
39
---
✔ Example 2: 83 - 18
```
83
- 18
----
65
```
- Ones: 3 - 8 → borrow → 13 - 8 =
5
- Tens: 7 (after borrowing) - 1 =
6
→ Result:
65
---
✔ Example 3: 63 - 51
```
63
- 51
----
12
```
- Ones: 3 - 1 =
2
- Tens: 6 - 5 =
1
→ Result:
12
---
✔ Example 4: 78 - 47
```
78
- 47
----
31
```
- Ones: 8 - 7 =
1
- Tens: 7 - 4 =
3
→ Result:
31
---
⚠️ Important Note:
Some problems require
borrowing, like:
#### Example 14: 89 - 57
```
89
- 57
----
32
```
- Ones: 9 - 7 =
2
- Tens: 8 - 5 =
3
→ Result:
32
No borrowing needed here.
---
#### Example 15: 75 - 19
```
75
- 19
----
56
```
- Ones: 5 - 9 → can’t do → borrow → 15 - 9 =
6
- Tens: 6 (after borrowing) - 1 =
5
→ Result:
56

💡 Tips for Students:
- Always start from the
right (ones).
-
Borrow only if the top number is smaller.
- After borrowing, reduce the tens digit by 1.
- Double-check your work!
