We line up the numbers vertically.
Step 2:
The digits in ones column are added. 3 + 3 + 2 = 8. So 8 is written below ones column.
Step 3:
Then the digits in tens column are added. 7 + 5 + 8 = 20. 0 is written below tens column and 2 is carried over to hundreds column.
Step 4:
In hundreds column, 4 + 6 + 2 = 12. 2 is written below hundreds column and 1 is carried over to thousands column.
Step 5:
In thousands column, 3 + 1 = 4. 4 is written below thousands column. So the final sum is 4208.
