Got to be missing something or not thinking about something or the guy who designed the clock wasn't as smart as he thought he was, LOL.
Maybe the Barbie doll was right, "Math is hard" :)
As I recall, a lot of people can’t remember that the factorial function is multiplying (duh), and some add the numbers together. But even that would be wrong, because it returns the sq. rt. of 45, when the person was obviously going for the sq. rt. of 36.
And the equation at 7 o’clock is obviously a typo, but at least he didn’t divide by zero.
Anyway, most of the clock is clever... [smiles]
