EXPANDED FORM

               A number written in the form of the sum of the place value of its digits is said

               to be in its expanded form.

                                                                            4
               Let us write the expanded form of the number  356.
                                   4   3  5  6


                                                          stands for 6 ones or 6
                                                          stands for 5 tens or 50

                                                          stands for 3 hundreds or 300

                                                                                          4
                                                                      4
                                                        stands for  thousands or  000
                                                 4
               So, the expanded form of  356 is:

                                           4
                               4 356  =  thousands + 3 hundreds + 5 tens + 6 ones
                                       =   4 000 + 300 + 50 + 6


                17  Write the numbers in expanded notation. One has been done for you.

                      (a)  2376 =  2  thousands +  3  hundreds +  7  tens +  6  ones


                      (b)   4 618 =        thousands +           hundreds +           ten  +        ones


                              4
                      (c)  51 9 =          thousands +           hundred  +           tens +        ones

                      (d)  7961 =          thousands +           hundreds +           tens +        one


                             4
                      (e)  9 85 =          thousands +           hundreds +           tens +        ones


                18  Write the numbers in expanded form. One has been done for you.

                                                         600
                                                                                          2
                                        1000
                      (a)  1692 = ________ + ________ + ________ + ________
                      (b)  3516 = ________ + ________ + ________ + ________
                                 4
                      (c)  593  = ________ + ________ + ________ + ________

                      (d)  6389 = ________ + ________ + ________ + ________

                      (e)  8051 = ________ + ________ + ________ + ________



                                                                 14
