Worksheets Crafter: To perform 2-digit addition, it is important to understand the basic concept of place value. Start by lining up the two numbers vertically, with the ones digit lined up in the rightmost column and the tens digit lined up in the leftmost column. Begin by adding the digits in the ones column. If the sum is less than 10, write it below the line in the ones column. If the sum is greater than 9, carry the tens digit over to the next column. Next, add the digits in the tens column, along with any carried over tens from the previous step. Write the total below the line in the tens column. Finally, combine the sum of the tens and ones columns to get the final answer. Remember to always check your work to ensure accuracy and practice regularly to improve speed and accuracy.
