### Adding 2-Digit Numbers: Learn

How to add two-digit numbers (for example 29 + 33).
• Place one number above the other number so that the tens' place digits and ones' place digits are lined up. Draw a line under the bottom number.  2 9 + 3 3
• Add the ones' place digits (9 + 3 = 12). This sum is a two-digit number, so place a one above the tens' place column and place the two below the line in the ones' place column.  1 2 9 + 3 3 2
• Add the tens' place digits (1 + 2 + 3 = 6) and place the answer below the line in the tens' place column.  1 2 9 + 3 3 6 2
