Adding two three digit numbers (for example 529 + 733) involves several steps.
Place one number above the other so that the hundreds, tens and ones
places are lined up. Draw a line under the bottom number.
529
733
Add the ones place digits (9 + 3 = 12). This number is larger
than 10 so place a one above the tens place column and place the two below the
line in the ones place column.

529
733
2
Add the tens place digits (1 + 2 + 3 = 6) and place the answer below
the line and in the tens place column.
529
733
62
Add the numbers in the hundreds place column (5 + 7 = 12) and place the 2
below the line and before the other number below the line. Place the 1 from the
twelve above the thousands place column.

The thousands place column only has a 1 in it which should be placed
below the line in the thousands place column.
