Regrouping is the process of exchanging values between the place value columns of a number. Explained simply, regrouping is moving digits from one place value column to another. We regroup in groups of ten when moving between the ones, tens, hundreds and thousands place value columns. 10 individual ones (units) can be regrouped as 1 ten.

How to regroup in subtraction?
When regrouping in subtraction, you cross out the number you are borrowing from (in our example, that would be the 3 in the tens column). You then make that number one less (in our example, it becomes a 2). Next, you add 10 to the ones column, which is represented by placing a one next to the top digit in the ones column. I placed the 12 in parentheses to show that, by adding the ten, you effectively make the top number two digits.
What does it mean to regroup if the number is greater than the number it is subtracted from?
In subtraction, regrouping means that you borrow 10 from the next column to the left. You then add that 10 to the column you needed to borrow for. Look at the example:
How to add 411 to tens?
You then add the tens column (1 + 7 + 3), which equals 11. Again, place the 1 underneath the tens column and regroup to the hundreds column. Finally, add the hundreds column (1 + 1 + 2), which equals 4, giving you the total 411 .
How to regroup 10 numbers into 1 ten?
To do this, you place the zero from the number 10 in the ones column and place the 1 above the tens column. Doing this indicates that there are 0 ones and 1 additional ten.

When is regrouping necessary?
Regrouping becomes necessary when the sum of a column exceeds 10. This has to do with how the decimal numeral system works, and is discussed below. To perform the addition algorithm however, simply "carry" a 1 over to the next column, then add it along with the next column, as in the example below.
What is the process of rearranging numbers to form groups of 10?

When do you regroup in math?

Can you regroup addition?
However, regrouping isn’t only for addition. You can also regroup in a subtraction problem. For example, let’s take the problem 24 – 16. Starting with the units, you can’t take 6 away from 4. So, you have to regroup one of the tens in the 20 into a group of ten units. Then, you take away 6 from 14. Your answer is 8. Finally, you check the tens side. You have one ten minus one ten, which is zero. So, the final answer is 8.
