            Comparison of Numbers

                     Different number of digits                           Same number of digits

             The number with more digits is always greater.    When the number of digits is same, start
                                                               comparing from the leftmost digit, i.e., the digit
                                                               at the thousands place.

            Look at the given examples.

              1.  Compare 2685 and 798.

                        2685         >        798
                     (4 digits)            (3 digits)

              2.  Compare 2982 and 3105.

                    2  9 8 2                                         3  1 0 5

                          2 at the thousands place                         3 at the thousands place


                   Since 2 < 3, 2982  <  3105.

              3.  Compare 4861 and 4539.
                    4  8 6 1                                         4  5 3 9


                   The digit at the thousands place is same in both the numbers. Thus, compare
                   the digits at the hundreds place.

                   4  8  6 1                                        4  5  3 9


                            8 at the hundreds place                          5 at the hundreds place

                   Since 8 > 5, 4861  >  4539.

              4.  Compare 5861 and 5875.

                    5   8  6 1                                       5   8  7 5

                   The digits at the thousands and hundreds place are same in both the numbers.
