                    Face Value and Place Value

                    Every digit in a number has a face value and a place value.


                                    Face Value                                       Place Value
                    •  The face value of a digit is the          •  The place value of a digit depends on its face
                       digit itself.                                value and its place in a number.

                    •   The face value of a digit never          •  The place value of a digit changes with
                       changes.                                     the change in its place.


                    Look at the given example.                                      You Should Know

                                                                                   values are 100 and 1.
                                    The face value of 6 is 6.

                                    The place value of 6 is 6 ones or 6.

                                    The face value of 5 is 5.

                                    The place value of 5 is 5 tens or 50.

                                    The face value of 1 is 1.

                                    The place value of 1 is 1 hundred or 100.
