Adding Without Regrouping (No Carry Over)

When the ones digits add up to 9 or less, you do not need to regroup. [1]

Let's add 24 + 13:

1. Line up the numbers vertically with the tens on the left and the ones on the right.
2. Add the ones column on the right: 4 + 3 = 7. Write 7 under the ones place.
3. Add the tens column on the left: 2 + 1 = 3. Write 3 under the tens place.
4. The final answer is 37
