The street sign says...

+-------------+ | Reserved | | Parking | | Post Office | | Hours | | Mon.-Fri. | | 8:00-4:30 | | Saturday | | 8:00-11:00 | +-------------+A pi-o-time at the Post Office in Warsaw, Illinois.

: is a delimiter the numbers are: 8 0 4 30 8 0 11 0 the Pi math is: (30 - 8 + 8 * 0) / (11 - 4) = 22/7 more Pi math: (11 * 4) / (30 - 8 - 8) = 44/14 more Pi math: (8 * 8 + sqrt(4)) / 11 + 30 / (0! + 0! + 0!) = 66/21 more Pi math: (8 * 11) / (30 - 8 + 4 + 0! + 0!) = 88/28 more Pi math: 11 / ((8 / (8 * 4 - 30)) - (0! / (0! + 0!))) = 11/3.5 observe... by definition, 0! = 1 22/7 approximates Pi (3.14) 11/3.5, 22/7, 44/14, 66/21, 88/28 are equivalent fractions Phi math: (0! + sqrt(sqrt(11 + 30 - 8 - 8))) / (4 - 0! - 0!) = Phi observe... Phi is the "golden ratio" Phi = (1 + sqrt(5))/2 Phi = 1.61803399... (irrational number) rsAgeEval: 30 + 11 - 0! + sqrt(8 + 8) + 4 + 0! + 0! = 50 * RoadHacker was 50 years young when he found this sign. rs42Eval: 30 - 11 + 8 + 8 + 4 + 0! + 0! + 0! = 42 * "Answer to Life, the Universe, and Everything." rs42Eval: ((4! / (0! + 0! + 0!)!)! / 8)! * sqrt(8 + 11 + 30) = 42 let f(n) = factorial(n) previous rs42Eval using function notation... f(f(f(4) / f(f(0) + f(0) + f(0))) / 8) * sqrt(8 + 11 + 30) = 42 more math: 30 - 11 - 8 - 8 - 4 + 0! + 0! = 0! fooish math: 0 * (8 + 4 + 30 + 8 + 0 + 11) = 0 fooish math: (8 + 4 + 30 + 8 + 0 + 11)^0 = 0!
