__Regrouping:__We regroup when we add. When the two number in the ones place add to a number bigger that 9 (2 digits), we need to take ten ones and regroup them in to the tens place.**Borrowing: We borrow when we subtract. If the top number in the ones place is smaller than the bottom number in the ones place, we need to borrow ten from the tens place.**
