Explain 1 way to add 3 digit numbers

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.  1 529 733   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  62Add 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. 1  529  733  262The thousands place column only has a 1 in it which should be placed below the line in the thousands place column.   529   733  1262
