Addition of Two 3-digit number with Regrouping

 

 

Example 1:- Add the following?

 

Explanation:

Step 1: Adding the digits at one’s place,

3 + 8 = 11

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 = 8

 

Step 3: Adding the digits at hundred’s place,

3 + 2 = 5

Hence, the sum of the given numbers is 581

 

Example 2:- Add the following?

 

Explanation:

Step 1: Adding the digits at one’s place,

6 + 9 = 15

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 + 4 + 1 = 9

 

Step 3: Adding the digits at hundreds place

3 + 5 = 8

Hence, the sum of the given numbers is 895

 

Example 3:- Add the following?

 

Explanation:

Step 1: Adding the digits at one’s place,

9 + 1 = 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,

0 + 9 + 1 = 10

 

Step 3: Adding the digits at hundreds place and the carry of 1,

5 + 3 + 1 = 9

Hence, the sum of the given numbers is 900
