Worksheets Crafter: To perform digit addition, start by lining up the numbers vertically, with the digits aligned in their respective places. Begin with the rightmost column and add the digits together. If the sum is a single digit, write it below the line. If the sum is a two-digit number, write the rightmost digit below the line and carry over the leftmost digit to the next column. Repeat this process for each column, carrying over as needed. Once all columns have been added, the final sum is the result of the digit addition. Double-check your work to ensure accuracy, and don't forget to carry over any remainders from the last column to the leftmost column if necessary. Practice digit addition regularly to improve your skills and speed.
