Addition of Three 3-digit numbers with Regrouping
Example 1:- Add the following?
Explanation:
Step 1: Adding the digits at one’s place,
7 + 5 + 6 = 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,
2 + 4 + 5 + 1 = 12
Since the number is more than 9, we need to carry over 1 to the hundreds place.
Step 3: Adding the digits at hundreds place and carry 1,
3 + 2 + 2 + 1 = 8
Hence, the sum of the given numbers is 828
Example 2:- Add the following?
Step 1: Adding the digits at one’s place,
5 + 3 + 2 = 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,
7 + 9 + 0 + 1 = 17
Since the number is more than 9, we need to carry over 1 to the hundreds place.
Step 3: Adding the digits at hundreds place and carry 1,
2 + 5 + 1 + 1 = 9
Hence, the sum of the given numbers is 970
Example 3:- Add the following?
Explanation:
Step 1: Adding the digits at one’s place,
5 + 2 + 5 = 12
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,
8 + 7 + 2 + 1 = 18
Since the number is more than 9, we need to carry over 1 to the hundreds place.
Step 3: Adding the digits at hundreds place and carry 1,
2 + 4 + 2 + 1 = 9
Hence, the sum of the given numbers is 982
