+ 5276
------
```
Ones: 8 + 9 + 6 = 23 → write 3, carry 2
Tens: 2 + 0 + 7 + 2 (carry) = 11 → write 1, carry 1
Hundreds: 7 + 3 + 2 + 1 (carry) = 13 → write 3, carry 1
Thousands: 4 + 1 + 5 + 1 (carry) = 11 → write 11
→ 11313

Problem 2:
```
8144
+ 892
+ 3168
------
```
Ones: 4 + 2 + 8 = 14 → write 4, carry 1
Tens: 4 + 9 + 6 + 1 = 20 → write 0, carry 2
Hundreds: 1 + 8 + 1 + 2 = 12 → write 2, carry 1
Thousands: 8 + 3 + 1 = 12 → write 12
