Worksheets Crafter: Digit addition is a fundamental mathematical operation that involves adding individual digits together to find the total sum. To perform digit addition, start by lining up the numbers to be added in a vertical column, with the ones digits aligned in the same column, then add the numbers from right to left, carrying over any sums greater than 9 to the next column. For example, when adding 348 + 179, start by adding the ones digits (8 + 9 = 17), write down the 7 and carry the 1 to the next column. Then, add the tens digits (4 + 7 + 1 = 12), write down the 2 and carry the 1 to the hundreds column. Finally, add the hundreds digits (3 + 1 = 4) to get the total sum of 527. Practicing digit addition regularly can help improve mental math skills and make more complex arithmetic tasks easier to tackle.
