Adding Four Digit Numbers How to add four digit numbers (for example 4529 + 6733): Place one number above the other so that the thousands', hundreds', tens' and ones' places are lined up. Draw a line under the bottom number. ``` 4529 6733 ``` 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 4529 6733    2 ``` Add the tens' place digits (1 + 2 + 3 = 6) and place the answer below the line and in the tens' place column. ``` 4529 6733   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. ``` 1 4529 6733  262``` Add the digits in the thousands' place column (1 + 4 + 6 = 11) and place the answer below the line in the thousands' place column. ```  4529  6733 11262``` Return to Top
