Place Value

             The value of a digit which depends upon the place where it occurs. It is

             known as the place value.
             The  all  3’s  in  number  3333  have  different  place  value  as  they  all  fall  in

             different place categories.


                                     Thousands            Hundreds                 Tens                Ones

                                                         Face Value


             The  face  value  of  a  digit  is  a  digit  itself,  respect  of  its  position  on  place

             value chart.

             Let us have a number 8243.
