What is regrouping in math? A: Regrouping is the borrowing of a value from one column of numbers to another to aid a mathematical operation. If one is subtracting, itâs necessary to regroup when the number at the top of a column is smaller than the one below it.
Regrouping in subtraction can seem very confusing at first, but it's quite simple if you remember that you are just borrowing 10 from the next column to the left and adding it to the column you're starting with. You can also regroup when subtracting numbers that are more than two digits.
