Frequently Asked Questions
What is long subtraction with regrouping?
Long subtraction with regrouping (also called borrowing) is a method for subtracting multi-digit numbers when the digit being subtracted is larger than the digit it's being subtracted from. You 'borrow' from the next higher place value to make the subtraction possible.
How does regrouping work in subtraction?
Regrouping works by taking 1 from the next higher place value (making it 10 in the current place value) and adding it to the current digit. For example, if you need to subtract 7 from 5, you borrow 1 from the tens place, making 5 become 15, then subtract 7 from 15 to get 8.
When do you need to regroup in subtraction?
You need to regroup when the bottom digit (subtrahend) is larger than the top digit (minuend) in any column. This happens when you can't subtract the bottom number from the top number without getting a negative result.
