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
