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!
