USE YOUR FINGERS TO MULTIPLY BY NINE

Hold your hands in front of you and bend the finger down that you want to multiply by nine. Count the fingers to the left and the right of the bent finger and combine them to produce the result. Eg: for 7 x 9, bend the seventh finger down, to the left there will be 6, and to the right there will be 3 fingers standing, thus 7 x 9 is 63. – Jeremy Reid, Graphic Designer, Belleville, Ontario, Canada
