These street signs were found on Pi Day 2009 in Tucson, Arizona.

The street signs say...

+--------------------+ | 5th St 500 E | ---------------------- | 3rd Ave 500 N | ---------------------- | STOP 4-Way | +--------------------+the numbers are: 5 500 3 500 4 the math is: sqrt(500 / (500 / 4)) + 3 = 5 rsPhiEval: ((500 / 500) + sqrt(5)) / (3! - 4) = Phi * Phi is the golden ratio and it approximates 1.61803399 rs42Eval: 5! / 3 + sqrt(4! / log(500 + 500)!) = 42 * 42 is the "Answer to Life, the Universe, and Everything" rsAgeEval: 4! * (5 - 3) + log(500 + 500) = 51 * RoadHacker was 51 years young when he found these signs more math: 500 / 500 * (5 - 3) = sqrt(4) more math: 5 - 4 = 3^(500 - 500) more math: cuberoot(500 / 4) - log(500 / 5) = 3 more math: log(500 + 500) / 3 + 4 = 5 more math: cuberoot(500 - 500 + 5 + 3) = sqrt(4) more math: avg(3, 500 / (500 / 5)) = 4 more math: avg(3, 5) = 500 / (500 / 4)Again, these street signs were found on Pi Day 2009 in Tucson, Arizona.
