Thus, 0.34 is greater than 0.331.

            In the above example, you can see 0.34 has less decimal digits than 0.331. It is easier to

            compare two decimals when you have the same number of decimal digits. So, an extra
            zero was written to the right of the digit 4 in the decimal 0.34. We are able to do this
            because 0.34 and 0.340 are equivalent decimals.

            Example  :  Compare each pair of decimals using the symbols <, > or =.

            Addition of Decimals

            Adding  decimals  is  very  similar  to  adding  whole  numbers  except  with  a  few  extra
            technical details. Recall that decimals are just fractions. We add fractions by adding the

            whole  number  parts  and  the  fractional  parts  separately,  carrying  the  1  from  the
