1. 8289 - 7146

```
8289
- 7146
------
1143
```

Explanation:
Start from the right:
- 9 - 6 = 3
- 8 - 4 = 4
- 2 - 1 = 1
- 8 - 7 = 1
So, 8289 - 7146 = 1143

2. 35716 - 20357

```
35716
- 20357
-------
15359
```

Step-by-step:
- 6 - 7 → can't do, borrow: 16 - 7 = 9, carry over
- 0 (after borrow) - 5 → can't do, borrow: 10 - 5 = 5, but next digit becomes 0 → need to go further
Actually:
- Units: 6 - 7 → borrow → 16 - 7 = 9
- Tens: 1 becomes 0 after borrow, 0 - 5 → borrow → 10 - 5 = 5
- Hundreds: 7 becomes 6 after borrow, 6 - 3 = 3
- Thousands: 5 - 0 = 5
- Ten thousands: 3 - 2 = 1

So: 35716 - 20357 = 15359

3. 9736 - 4948

```
9736
- 4948
------
4788
```

Steps:
- 6 - 8 → borrow → 16 - 8 = 8
- 3 becomes 2 → 2 - 4 → borrow → 12 - 4 = 8
- 7 becomes 6 → 6 - 9 → borrow → 16 - 9 = 7
- 9 becomes 8 → 8 - 4 = 4

So: 9736 - 4948 = 4788

4. 48985 - 23897

```
48985
- 23897
-------
25088
```

Steps:
- 5 - 7 → borrow → 15 - 7 = 8
- 8 becomes 7 → 7 - 9 → borrow → 17 - 9 = 8
- 9 becomes 8 → 8 - 8 = 0
- 8 becomes 7 → 7 - 3 = 4
- 4 - 2 = 2

Wait! Let's check:

Actually:
- Units: 5 - 7 → borrow → 15 - 7 = 8
- Tens: 8 becomes 7, 7 - 9 → borrow → 17 - 9 = 8
- Hundreds: 9 becomes 8, 8 - 8 = 0
- Thousands: 8 becomes 7, 7 - 3 = 4
- Ten thousands: 4 - 2 = 2

So: 48985 - 23897 = 25088

5. 19375 - 52310

Wait — 19375 is less than 52310, so this will be negative.

We compute:

```
52310
- 19375
-------
32935
```

But since it's 19375 - 52310, the result is:

-32935

So: 19375 - 52310 = -32935

6. 342146 + 431264

```
342146
+ 431264
--------
773410
```

Add column by column:

- 6 + 4 = 10 → write 0, carry 1
- 4 + 6 + 1 = 11 → write 1, carry 1
- 1 + 2 + 1 = 4
- 2 + 1 = 3
- 4 + 3 = 7
- 3 + 4 = 7

So: 342146 + 431264 = 773410

---

7. 457653 + 137246

```
457653
+ 137246
--------
594899
```

Add:
- 3 + 6 = 9
- 5 + 4 = 9
- 6 + 2 = 8
- 7 + 7 = 14 → write 4, carry 1
- 5 + 3 + 1 = 9
- 4 + 1 = 5

So: 457653 + 137246 = 594899

---

8. 57638 + 28419

```
57638
+ 28419
-------
86057
```

Add:
- 8 + 9 = 17 → write 7, carry 1
- 3 + 1 + 1 = 5
- 6 + 4 = 10 → write 0, carry 1
- 7 + 8 + 1 = 16 → write 6, carry 1
- 5 + 2 + 1 = 8

So: 57638 + 28419 = 86057

---

9. 29834 + 13975

```
29834
+ 13975
-------
43809
```

Add:
- 4 + 5 = 9
- 3 + 7 = 10 → write 0, carry 1
- 8 + 9 + 1 = 18 → write 8, carry 1
- 9 + 3 + 1 = 13 → write 3, carry 1
- 2 + 1 + 1 = 4

So: 29834 + 13975 = 43809
