A nice clock that is displayed instead of hours, simple math formulas only with the number 9.

I wouldn’t buy this clock until they fix 5:00… the square root of 9 factorial minus one is 601.395219105

Is just because the factorial must be otside the square root then everythink is OK.

Yeah, the ! should be placed outside the root so that the order of operation forces the resolution of the root prior to the factorial operation. i.e.

(√9)!-(9/9)

=3!-1

=6-1

=5
