                example 2. Which is greater?

                             a.  2,538 or 2,438                           b.  73,464 or 73,477
                Solution.  a.  2 5 3 8                  2 4 3 8           b.    7 3 4 6 4                7 3 4 7 7

                                                                                                =

                                             =                                                  =

                                             >                                                  =
                                                                                                <

                             So, 2,538 > 2,438.                                So, 73,464 < 73,477.

                Ascending and Descending Orders

                Ascending or increasing order means writing numbers from the smallest to the greatest.

                example 3. Arrange the following numbers in ascending order:

                                               45,656;  45,352;  45,682;  45,082

                Solution. First, we arrange the given numbers in the place value chart and then start

                comparing.
                                                                                                   TTh  Th H     T   O
                45,082 is the smallest number and 45,682 is the greatest number.                    4   5    6   5    6

                Also, 45,352 is smaller than 45,656.                                                4   5    3   5    2

                So,          45,082 < 45,352 < 45,656 < 45,682.                                     4   5    6   8    2

                Descending  or decreasing  order  means writing numbers from                        4   5    0   8    2

                the greatest to the smallest.

                example 4. Arrange the following numbers in descending order:

                                                2,356;  45,605;  8,956;  67,897

                Solution. First, we arrange the given numbers in the place value chart and then start
                comparing.
                                                                                                   TTh  Th H     T   O
                Here, two  numbers  45,605  and  67,897 have 5  digits  such that
                                                                                                        2    3   5    6
                67,897 > 45,605 and two numbers 2,356 and 8,956 have 4 digits,
                                                                                                    4   5    6   0    5
                in which 8,956 > 2,356.
                                                                                                        8    9   5    6
                So,          67,897 > 45,605 > 8,956 > 2,356.
                                                                                                    6   7    8   9    7
