Riddle: How many numbers are there on a clock?

Show answer

There are 15 numbers on a clock. These are, in clockwise order starting right at the top: 1, 2, 1, 2, 3, 4, 5, 6, 7, 8, 9, 1, 0, 1 and 1.

Strictly speaking, in the math universe, there are really only 10 “numbers.” These are: 1, 2, 3, 4, 5, 6, 7, 8, 9 and 0.
