Addition with Regrouping

Two Digit Addition with Regrouping

​How to work out the answer

Step 1: Arrange the numbers in columns according to their place values.

Step 2: Just like normal addition, start adding from ones place, moving on to tens place.

Step 3: If the sum in any of the columns is more than 9, we regroup this sum into tens and ones. We write the ones digit of this sum under that particular column and we carry over the tens digit of the sum to the next column.

Step 1: Place 18 and 5 in proper columns according to their place values one below the other as shown above.

Step 2: Add 8 and 5 which comes to 13. Since 13 has exceeded 9 we will regroup it. In other words, 13 is a two-digit number so we will regroup this sum into tens and ones. This means we will carry over the tens digit of the sum to the preceding column and write the ones digit in that particular column. Here, we will write 3 in ones column, and carry over 1 to the tens column.

Step 3: This 1 which is a carryover in the tens column will be added to the existing number which is 1. So the sum of this column will be 2. Therefore, the sum of 18 + 5 = 23.
