Addition of 3-Digit Numbers Without Carrying

In 1st grade, we have learnt how to add 1-digit and 2-digit numbers. Here, we will learn simple addition of 3-digit numbers without regrouping (without carrying). 

We add 3-digit numbers in the same way as we add 2-digit numbers.


Let us add 423 and 215.

3 Digit Addition - without Regrouping

To add the above numbers, we take the following steps:

Step I: Write the given numbers in column form as shown.


Step II: Add the ones:

3 + 5 = 8

Write 8 under ones column.


Step III: Add the tens:

2 + 1 = 3

Write 3 under tens column.


Step IV: Add the hundreds:

4 + 2 = 6

Write 6 under hundreds column.

Addition of 3-Digit Numbers Without Carrying

Thus, the sum of 423 and 215 is 638.
