For example, to multiply by 9, straighten your fingers and then put your hands on a table palms down. Now, to multiply any number by 9, just bend the corresponding finger. The fingers “before“ mean tens, and those ”after“ mean units. For example, to multiply 7 by 9, bend the 7th finger. 6 fingers remain “before” and 3 ”after." Thus we get the answer: 7×9 = 63.
