Worksheets Crafter: To perform 2-digit addition, start by aligning the two numbers vertically, with the ones digit lined up. Begin by adding the ones column together, carrying over any tens if the total is greater than 9. Next, move on to the tens column, adding the two numbers along with any carried over tens from the ones column. Continue this process until both columns have been added, arriving at the final sum. Remember to double-check your work to ensure accuracy and practice regrouping when necessary. With practice and patience, mastering 2-digit addition can become second nature.
