Hello,
When students learn to add numbers by hand, they first add the rightmost numbers, then move gradually to the left. For example, for adding 236 and 260, they first calculate 6 + 0 = 6, then 3+ 6 = 9 and finally 2 + 2 = 4. In other words, they would write 6, then 9 and finally 4.
However, on computers, numbers are usually entered starting with the leftmost digit and moving to the right. Therefore, the number 496 would be entered as 4, then 9 and finally 6.
The following example includes a script to enter the answer with the rightmost digit first then moving to the left, as a student would write it when learning how to add. So the number 496 was entered as 6, then 9 and finally 4:
