1.3                            COUNTING COMBINATIONS










                  Let us represent the different combinations of two numbers that add up to
                  the same number.

                  For example, the combination of numbers that add up to 6 are shown below.





                                                                                           6    +     0    =     6







                                                                                           5    +     1    =     6







                                                                                           4    +     2    =     6







                                                                                           3    +     3    =     6






                                                                                           2    +     4    =     6







                                                                                           1    +     5    =     6







                                                                                           0    +     6    =     6




                  Similarly, we can create different combinations for different numbers.
