how many numbers are there?

Answer 2

and how about we subtract, say 20, from everything

27, 18, 20, 21, 29, 33, 12, 14, 34, 10, 16, 21, 22, 24, 26


7, -2, 0, 1, 9, 13, -8, -6, 14, -10, -4, 1, 2, 4, 6

not that that is required, but it might help in sorting the numbers from smallest to biggest ....
