                  Expanded Form and Short Form of a Number

                  The expanded form of a number is the sum of the place values of its digits.

                  The short form of a number is the numeral that is written using face value of the

                  digits.

                  Look at the following numbers.

                   (a)     H T O      Place                           (b)     H T O      Place

                           5 0 7 value                                        2 6 9 value

                                         7                                                  9

                                         0                                                  60

                                       500                                                 200

                          Expanded form: 500 + 0 + 7                         Expanded form: 200 + 60 + 9

                          Or 5 hundreds + 0 tens + 7 ones                    Or 2 hundreds + 6 tens + 9 ones

                          Short form: 507                                    Short form: 269
