You should regroup when the value of a digit in a given place exceeds the maximum allowed for that place. For example, in addition, if the sum of digits in a column exceeds 9, you regroup by carrying over to the next left column. In subtraction, regrouping is necessary when you need to subtract a larger digit from a smaller one in a particular place value. Always look for opportunities to consolidate or carry over when the values surpass their respective limits.
