Solution:

To solve this addition problem, we add the numbers column by column, starting from the rightmost column (the ones place).

1. Ones place: 4 + 6 = 10. Write down 0 and carry over 1 to the tens place.
2. Tens place: 5 + 7 + 1 (carry-over) = 13. Write down 3 and carry over 1 to the hundreds place.
3. Hundreds place: 8 + 3 + 1 (carry-over) = 12. Write down 12.
