### Addition of 3-Digit Numbers With out Carrying

In 1st grade, we now have learnt the way to add 1-digit and 2-digit numbers. Right here, we’ll study easy addition of 3-digit numbers with out regrouping (with out carrying).

We add 3-digit numbers in the identical means as we add 2-digit numbers.

Allow us to add 423 and 215.

So as to add the above numbers, we take the next steps:

 Step I: Write the given numbers in column kind as proven. Step II: Add those: 3 + 5 = 8 Write 8 beneath ones column. Step III: Add the tens: 2 + 1 = 3 Write 3 beneath tens column. Step IV: Add the lots of: 4 + 2 = 6 Write 6 beneath lots of column.

Thus, the sum of 423 and 215 is 638.
