Clock of 9s
I’ve seen this on a couple other blogs now, but I haven’t been able to find it for sale anywhere. This makes me think it was the work of a renegade math geek at some college. You can buy a plain clock and replace the face with any kind of printed art, and I might just do that I like it that much! There are only a couple tricky numbers: 5 made sense after Cathy pointed out it was the factorial of the square root, not the square root of the factorial. 7 gave me pause until I did the proof that .99 repeating actually does = 1 (n=.99rep;10n=9.99rep;10n-n=9;9n=9;n=1), and on 9 I can’t make out the exponents, can you figure them out?
