                example 3. Find the first five multiples of 2 as well as 3.
                Solution.  2 × 1 = 2            2 × 2 = 4         2 × 3 = 6           2 × 4 = 8         2 × 5 = 10

                The first five multiples of 2 are 2, 4, 6, 8 and 10.
                               3 × 1 = 3        3 × 2 = 6         3 × 3 = 9          3 × 4 = 12         3 × 5 = 15

                The first five multiples of 3 are 3, 6, 9, 12 and 15.

                example 4. Find the first five even multiples of 9.
                Solution. The first five even numbers are 2, 4, 6, 8 and 10. Multiply each of these even

                numbers by 9.
                              9 × 2 = 18        9 × 4 = 36        9 × 6 = 54         9 × 8 = 72        9 × 10 = 90
                The first five even multiples of 9 are 18, 36, 54, 72 and 90.

                example 5. Find the first five odd multiples of 9.

                Solution. The first five odd numbers are 1, 3, 5, 7 and 9. Multiply each of these odd numbers
                by 9.
                               9 × 1 = 9        9 × 3 = 27        9 × 5 = 45         9 × 7 = 63         9 × 9 = 81

                Thus, the first five odd multiples of 9 are 9, 27, 45, 63 and 81.
