                  Rule 1. A 2-digit number is always greater than a 1-digit number.

                                           T O         T O                         T O         T O
                  examples:  a.                                             b.
                                           4 2 >           9                       5 4 >            7

                  Rule 2.  When two  2-digit  numbers  are compared,  the  number  with  the

                            greater tens digit is the greater number.

                  examples:  a.    T O                     T O              b.     T O             T O
                                           8 6       >     5 1                     5 9       >     4 7

                                                     >                                       >

                                    Thus,  86 > 51  or  51 < 86                  Thus,  59 > 47  or  47 < 59

                  Rule 3.  When two 2-digit numbers have the same tens digit, the number with

                             the greater ones digit is the greater number.

                  examples:  a.            T O            T O               b.     T O             T O

                                           5 4       >    5 2                      6 9       >     6 8

                                                   =                                        =
                                                        >                                        >

                                    Thus,   54 > 52  or  52 < 54                 Thus,   69 > 68  or  68 < 69

                  ordering numbers

                  We have already learnt how to arrange numbers in ascending and
                  descending order.

                  Let us arrange the numbers 75, 68, 84, 47 and 90 in                               T O
                  descending order.                                                                 7 5

                  We know that in descending order, the numbers are                                 6 8
                  arranged from the greatest to the smallest.                                       8 4

                  So, the given numbers in descending order are                                     4 7        Smallest

                  90 > 84 > 75 > 68 > 47                                                            9 0        Greatest
