ADDITION OF DECIMAL

Addition of Decimal

If we wish to add two or more decimal numbers then we have to follow the following steps –

First, we have to write the numbers one below the other with the decimal point in a line and for every decimal number’s position should be as per the same vertical line position of the decimal point.

Then we need to add the numbers and place the decimal point in the sum in line with the other decimal points. To make convenient we change the decimal into like decimal which means decimal with an equal number of digits after the decimal point by adding zeros ‘0’ to the right of the digits in the decimal places.

 

Example. 

1)  Add  23.124, 452.0215, 124.211 and 12.24

Ans.)        023 . 1240

              452 . 0215

              124 . 2110

          +   012 . 2400

        -------------------

              611 . 5965    

So, the answer is  611.5965      (Ans.)

 

 

2)   Add  134.24, 52.0255, 240.201 and 142.204

Ans.)         134 . 2400

               052 . 0255

               240 . 2010

        +      142 . 2040

        --------------------

                568 . 6705

So, the answer is 568.6705          (Ans.)
