Adding 4-Digit Numbers: Learn

• 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.

  	4	5	2	9
  +	6	7	3	3

• 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.

  	4	5	2	9

• Add the tens place digits (1 + 2 + 3 = 6) and place the answer below the line and in the tens place column.

  	4	5	2	9

• 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.
