Problem 1:

```
584,445
+ 31,496
+ 318,587
---------
```

Step-by-step addition:

Start from the rightmost digit (units place):

- Units: 5 + 6 + 7 = 18 → write down 8, carry over 1
- Tens: 4 + 9 + 8 + 1 (carry) = 22 → write down 2, carry over 2
- Hundreds: 4 + 4 + 5 + 2 = 15 → write down 5, carry over 1
- Thousands: 8 + 1 + 8 + 1 = 18 → write down 8, carry over 1
- Ten thousands: 5 + 3 + 1 + 1 = 10 → write down 0, carry over 1
- Hundred thousands: 5 + 0 + 3 + 1 = 9

So, total = 934,028

✔ Answer: 934,028
