            Multiplication Facts

                •  Two or more numbers can be multiplied in any order.  Their product always

                   remains the same.
                  For example, 6 × 8 = 48 and 8 × 6 = 48

                •  When a number is multiplied by 1, the product is                   Mental Maths
                   the number itself.

                  For example, 11 × 1 = 11 or 1 × 11 = 11                            (a)  175 × 1 = ?
                                                                                     (b)  162 × 0 = ?
                •  When a number is multiplied by 0, the product is
                   always 0.

                  For example, 9 × 0 = 0 and 12 × 0 = 0


            Patterns in Tables

            There is a pattern in tables that can help you to memorize the tables easily.
            Observe the pattern in the table of 9.

                   1 × 9 = 9         (0 + 9 = 9)                      6 × 9 = 54        (5 + 4 = 9)

                   2 × 9 = 18        (1 + 8 = 9)                      7 × 9 = 63        (6 + 3 = 9)

                   3 × 9 = 27        (2 + 7 = 9)                      8 × 9 = 72        (7 + 2 = 9)

                   4 × 9 = 36        (3 + 6 = 9)                      9 × 9 = 81        (8 + 1 = 9)

                   5 × 9 = 45        (4 + 5 = 9)                     10 × 9 = 90        (9 + 0 = 9)

            Note that the sum of the digits of the product is always 9.
