This parking sign is on Main Street in Watertown, Wisconsin.

The parking sign says...

+--------------+ | 2 Hr Parking | | 9am - 5pm | | Friday | | 9am - 9pm | +--------------+the numbers are: 2 9 5 9 9 the math is: (9 / 9 + 9) / 5 = 2 more math: 9 / sqrt(9) * (5 - 2) = 9 more math: sqrt(9) + sqrt(9) + 5 - 2 = 9 more math: sqrt(9 * 9) / 9 = log(5 * 2) more math: 5 - cuberoot(9 + 9 + 9) = 2 more math: 9 - sqrt(sqrt(9)! * sqrt(9)!) + 2 = 5 rs42Eval: 5 * 9 - 2 - 9 / 9 = 42 * 42 is the "Answer to Life, the Universe, and Everything" rsAgeEval: 5! / 2 - sqrt(9) - sqrt(9) - sqrt(9) = 51 * RoadHacker was 51 years young when he found this sign rsAgeEval: 5^2 + 9 + 9 + 9 = 52 * MathBabbler was 52 years young when he found this equation rsPhiEval: (sqrt(9) - 2 + sqrt(5)) / (sqrt(9)! / sqrt(9)) = Phi * Phi is the golden ratio and it approximates 1.61803399 rsStateEval: summation(5, 9) - 2 - 9 / sqrt(9) = 30 * This sign was found in Wisconsin and Wisconsin was the 30th state admitted to the Union observe... summation(5, 9) = 5+6+7+8+9 = 35 Wolfram|Alpha: sum j, j=5 to 9 rsPiEval: summation(2, 9) / (sqrt(9) * sqrt(9) + 5) ~= Pi * 44/14 approximates Pi (3.14) rounded to nearest hundredth another rs42Eval: summation(9 / 9, 9) - 5 + 2 = 42 * 42 is the "Answer to Life, the Universe, and Everything" observe... summation(9 / 9, 9) = summation(1, 9) = 45
