Addition with Regrouping

When we add 2-digit numbers, sometimes we need to regroup.

Regrouping is done when the sum of the digits in the ones column is 10 or more.

Add the ones; write 3 under ones column. Regroup or carry over 1 ten to the tens column.

Add the tens digits; 1 + 6 + 2 = 9. Write 9 under the tens column.
