Addition of Three 2-digit numbers with Regrouping
Example 1:- Add the following?
Explanation:
Step 1: Adding the digits at one’s place,
3 + 3 + 4 = 10
Since the number is more than 9, we need to carry over 1 to the tens place.
Step 2: Adding the digits at tens place and the carry of 1,
2 + 1 + 2 + 1 = 6
Hence, the sum of the given numbers is 60
Example 2:- Add the following?
Step 1: Adding the digits at one’s place,
9 + 0 + 9 = 18
Since the number is more than 9, we need to carry over 1 to the tens place.
Step 2: Adding the digits at tens place and the carry of 1,
4 + 1 + 1 + 1 = 7
Hence, the sum of the given numbers is 78
Example 3:- Add the following?
Explanation:
Step 1: Adding the digits at one’s place,
7 + 9 + 3 = 19
Since the number is more than 9, we need to carry over 1 to the tens place.
Step 2: Adding the digits at tens place and the carry of 1,
5 + 2 + 1 + 1 = 9
Hence, the sum of the given numbers is 99
