Regrouping simply means putting the 2+ answers into a group and subtracting all the answers together.
453 - 618 in regrouping = -165

i love regrouping it is fun the end
Numbers that would require regrouping in the ones place when added to 21 are any numbers from 9 to 19. When adding a number in this range to 21, the sum will exceed 30, necessitating regrouping in the ones place to carry over to the tens place. For example, when adding 19 to 21, the sum is 40, requiring regrouping.
