ADDITION WITH REGROUPING

Addition with regrouping consists of addition problems where the answer to the calculation is 10 or a bigger number.

For example, 7 + 3 =10

STEPS TO SOLVE REGROUPING ADDITION

The steps to solve regrouping addition problems are the following:

If the column being added doesn’t have a carry-over (or if the number is lower than 10), write the answer under the column.

if the column being added has a carry-over (or if the number is equal to or greater than 10), write the 1s-place numbers down under the bar and take note of the 10s-place number in the next column to add them later.

ADD WITH REGROUPING

Let’s try an example on Add with Regrouping:

Start by adding the 1s-place columns:

This number is greater than 10, so that means you need to write 3 under the 1s-place column and the 1 (the carry-over) above the next column.

Now, you just add the next column, and don’t forget about the carry-over:

This number also has a carry-over. Write the 4 down in the column of the 10s-place and bring the 1 up to the next column.
