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

#7 = okay. My children will get tattoos on their fingers; the counts from 6 to 10, haha. Or better: all 25 possible results (6..10 * 6..10) on the back-side of the hand.
#10 = false: I have a 110-degrees-hand. My third finger is not 45, it is 30.
