4-Digit Numbers                                                                                           23

        Rule 5:  If the digits at all places are same, the numbers                          Th     H     T     O
                   are equal. Let us compare 3456 and 3456.                                  3     4      5     6

                                                                                             3     4      5     6


                                                                                           3 = 3       5 = 5

                                                                                                 4 = 4        6 = 6

                                                                                                So, 3456 = 3456
        Ascending and Descending Order


        When we arrange the  numbers from  the  smallest  to the                             Th     H     T     O

        greatest, the numbers are in ascending order. Let us take                             3     2     2     5
        the numbers 3225, 6324 and 9568.                                                      6     3     2     4

        First we put these numbers in place value chart and then                              9     5     6     8
        compare the numbers.                                                                        3 < 6 < 9

        Therefore, 3225 is the smallest number and 9568 is the greatest number.

        Hence, the numbers in ascending order are 3225 < 6324 < 9568.

        When we arrange the numbers from the greatest to the smallest, the numbers are in
        descending order. Let us take the numbers 3625, 5679 and 3735.

        First we put numbers in place value chart and then compare them.


               Th     H     T     O                                          Th     H     T     O

                3     6     2     5                                           3     6     2      5
                5     6     7     9                                           3     7     3      5

                3     7     3     5
                                                                           3 = 3

             3 < 5
             So, 5679 is the greatest.                                           6 < 7       So, 3625 < 3735


        Hence, the numbers in descending order are 5679 > 3735 > 3625.




             Let's Try


        Example:         Rewrite  the  following  numbers  fi rst  in  ascending  order  and  then  in
                         descending order:

                         4538, 4927, 5132, 2839, 1003
   20   21   22   23   24   25   26   27   28   29   30
