Two digit addition with regrouping

It is the process of adding two-digit numbers where the sum of the digits in a column exceeds 9, requiring carrying over to the next column.

You regroup by carrying over 1 to the tens place and writing down the remainder in the ones place.

70

36

You add the ones place (7 + 1 = 8) and the tens place (2 + 3 = 5) to get 58.

Align the numbers by place value (ones under ones, tens under tens).

Regrouping means to carry over a value from one column to the next when the sum exceeds 9.

Add the ones place: 6 + 9 = 15, regroup 1 to the tens place.
