1a: 3716 + 42
Write them aligned:
```
3716
+ 42
------
```
Start from the right:
- Ones: 6 + 2 = 8
- Tens: 1 + 4 = 5
- Hundreds: 7 + 0 = 7
- Thousands: 3 + 0 = 3
→
3758
---
1b: 9524 + 261
```
9524
+ 261
------
```
- Ones: 4 + 1 = 5
- Tens: 2 + 6 = 8
- Hundreds: 5 + 2 = 7
- Thousands: 9 + 0 = 9
→
9785
---
1c: 5634 + 4365
```
5634
+ 4365
------
```
- Ones: 4 + 5 = 9
- Tens: 3 + 6 = 9
- Hundreds: 6 + 3 = 9
- Thousands: 5 + 4 = 9
→
9999
---
2a: 4237 + 605
```
4237
+ 605
------
```
- Ones: 7 + 5 = 12 → write 2, carry 1
- Tens: 3 + 0 + 1 (carry) = 4
- Hundreds: 2 + 6 = 8
- Thousands: 4 + 0 = 4
→
4842
---
2b: 1624 + 346
```
1624
+ 346
------
```
- Ones: 4 + 6 = 10 → write 0, carry 1
- Tens: 2 + 4 + 1 = 7
- Hundreds: 6 + 3 = 9
- Thousands: 1 + 0 = 1
→
1970
---
2c: 3568 + 5413
```
3568
+ 5413
------
```
- Ones: 8 + 3 = 11 → write 1, carry 1
- Tens: 6 + 1 + 1 = 8
- Hundreds: 5 + 4 = 9
- Thousands: 3 + 5 = 8
→
8981

Final Answer:
1a: 3758
1b: 9785
1c: 9999
2a: 4842
2b: 1970
2c: 8981
