How to Add with Regrouping and Some Examples

In today’s post, we are going to learn how to add with regrouping. 

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

For example, 6 + 7 = 13

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.

Let’s try an example on Add with Regrouping:

add with regrouping

Start by adding the 1s-place columns:

add with regroupingThis 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.

add with regrouping

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

add with regrouping

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.

add with regrouping

Now, we just need to add the last column:

add with regrouping

The only thing left is to write that number underneath in its appropriate column:

add with regrouping

And the final answer to this addition problem is 643. Did you get it right?
