Addition of 5-Digit and 6-Digit Numbers

When we add 5-digit numbers, we first add the ones, then the tens, then the

hundreds followed by the thousands and lastly the ten thousands.

Same as the addition of 5-digit numbers, when we add 6-digit numbers

after adding ten thousands, we add the lakhs at the end.

Look at some examples of addition.

Without Regrouping

Example : Add 64321 and 34232.

Step 1 : Adding ones Step 2 : Adding tens Step 3 : Adding hundreds

6 4 3 2 1 6 4 3 2 1 6 4 3 2 1
+ 3 4 2 3 2 + 3 4 2 3 2 + 3 4 2 3 2

3 5 3 5 5 3

Step 4 : Adding thousands Step 5 : Adding ten thousands

6 4 3 2 1 6 4 3 2 1
\ The sum of 64321
