These street signs were found on Pi Day 2009 along 4th Avenue in Tucson, Arizona.

The street signs say...

+----------------+ | Speed Limit 25 | ------------------ | 2 Hour Parking | | 8am - 5pm | ------------------ | Next 3 Blocks | +----------------+the numbers are: 25 2 8 6 3 the math is: (25 - 6 - 3) / 2 = 8 rsPiEval: (25 - 3) / ((8 + 6) / 2) = Pi * 22/7 approximates Pi (3.14) rounded to nearest hundredth rsPhiEval: ((3 - 2) + sqrt(sqrt(25))) / (8 - 6) = Phi * Phi is the golden ratio and it approximates 1.61803399 rs42Eval: 8 * 6 - 3 - sqrt(25) + 2 = 42 * 42 is the "Answer to Life, the Universe, and Everything" rsAgeEval: 25 * (8 - 6) + 3 - 2 = 51 * RoadHacker was 51 years young when he found these signs rsHwyEval: (25 - 6 - 3) / (8 / 2) = 4 * These signs were found on 4th Avenue more math: (8 + 6 / 3) / 2 = sqrt(25) more math: (8 - 6 + 3)^2 = 25
