When do you need to regroup in addition?

If the only operation you are working with is addition you don't need to. However, if dealing with a long list of numbers, it may be useful to regroup into tens and hundreds and other "round numbers" that you can sum together quickly at the end. For example 12 + 26 + 88 + 74 = 12 + 88 + 26 + 74 = (12 + 88) + (26 + 74) = 100 + 100 = 200


When might i need to regroup more than one time?

You might need to regroup more than once when performing multi-digit addition or subtraction, especially when the sum or difference of two numbers exceeds the place value of the column you are working in. For example, when adding numbers like 456 and 378, regrouping may be required in both the tens and hundreds columns. Similarly, when subtracting numbers like 804 and 297, regrouping may be necessary multiple times to ensure accurate results.
