Let's solve each subtraction problem step by step. We'll use
column subtraction (also known as borrowing when needed).
---
1. $ 92 - 89 $
```
92
- 89
----
3
```
- 2 - 9 → can't do, borrow 1 from 9 → 12 - 9 = 3
- 8 (after borrowing) - 8 = 0
✔ Answer: 3

2. $ 96 - 78 $
```
96
- 78
----
18
```
- 6 - 8 → can't do, borrow 1 → 16 - 8 = 8
- 8 (after borrowing) - 7 = 1
✔ Answer: 18

3. $ 95 - 67 $
```
95
- 67
----
28
```
- 5 - 7 → can't do, borrow → 15 - 7 = 8
- 8 - 6 = 2
✔ Answer: 28

4. $ 94 - 56 $
```
94
- 56
----
38
```
- 4 - 6 → borrow → 14 - 6 = 8
- 8 - 5 = 3
✔ Answer: 38

5. $ 93 - 45 $
```
93
- 45
----
48
```
- 3 - 5 → borrow → 13 - 5 = 8
- 8 - 4 = 4
✔ Answer: 48

6. $ 92 - 34 $
```
92
- 34
----
58
```
- 2 - 4 → borrow → 12 - 4 = 8
- 8 - 3 = 5
✔ Answer: 58

7. $ 91 - 23 $
```
91
- 23
----
68
```
- 1 - 3 → borrow → 11 - 3 = 8
- 8 - 2 = 6
✔ Answer: 68
---
8. $ 91 - 12 $
```
91
- 12
----
79
```
- 1 - 2 → borrow → 11 - 2 = 9
- 8 - 1 = 7
✔ Answer: 79

9. $ 93 - 59 $
```
93
- 59
----
34
```
- 3 - 9 → borrow → 13 - 9 = 4
- 8 - 5 = 3
✔ Answer: 34

10. $ 96 - 39 $
```
96
- 39
----
57
```
- 6 - 9 → borrow → 16 - 9 = 7
- 8 - 3 = 5
✔ Answer: 57
---
11. $ 93 - 98 $
Wait! This is
93 - 98, but 93 < 98 → result will be negative.
```
93
- 98
----
-5
```
- Since 93 < 98, we reverse the subtraction: 98 - 93 = 5 → then add a negative sign.
✔ Answer: -5
---
12. $ 95 - 87 $
```
95
- 87
----
8
```
- 5 - 7 → borrow → 15 - 7 = 8
- 8 - 8 = 0
✔ Answer: 8
