Key concepts
3 concepts
- 1
When adding two-digit numbers, you always start by adding the ones place, and if the sum is 10 or more, you need to regroup.
- 2
To regroup, you take 10 ones and group them together to make one ten, which is then added to the tens place.
- 3
After regrouping, you add the numbers in the tens place, including any carried tens, to find the final sum.
