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.
