### Adding 4-Digit Numbers: Learn

How to add three-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.  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.  1 4 5 2 9 + 6 7 3 3 2
• Add the tens place digits (1 + 2 + 3 = 6) and place the answer below the line and in the tens place column.  1 4 5 2 9 + 6 7 3 3 6 2
• 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 4 5 2 9 + 6 7 3 3 2 6 2
• Add the digits in the thousands' place column (1 + 4 + 6 = 11) and place the answer below the line in the thousands' place column.  1 5 2 9 + 7 3 3 1 1 2 6 2
