BARS::Nawiliwili Park on the Island of Kauai in Hawaii

This road sign is on the Hawaiian Island of Kauai.

The road sign says...

   +-------------------+
   | Airport      2 mi |
   |              3 km |
   | Lihue        2 mi |
   |              3 km |
   +-------------------+
   the numbers are:  2  3  2  3 

   the math is:  3! + 2 = 2^3

   [solve for 3!]  2^3 = 3! + 2

MathBabbler noticed that mileage-to-kilometer ratios are not correct on this road sign.

   observe...  1 mi = 1.609344 km

   [exercise]  fix the road sign

   +--------------------------+
   | Airport      2 mi        |
   |              ________ km |   [round to nearest hundredth]
   | Lihue        2 mi        |
   |              ________ km |   [round to nearest hundredth]

There is a squared-numbered 25 mph speed limit sign beyond this road sign.

   the numbers are:  2  3  2  3  25

   the math is:  (2 + 3) * (2 + 3) = 25

   more math:  log(sqrt(25 * 2 * 2)) * 3 = 3

   more math:  (sqrt(3! * 3!) - sqrt(25)) * 2 = 2

   rsPhiEval:  (3 / 3 + sqrt(sqrt(25))) / sqrt(2 + 2) = Phi
   * Phi is the golden ratio and it approximates 1.61803399

   rsPiEval:  (25 - 3) / (2 + 2 + 3) = Pi
   * 22/7 approximates Pi (3.14) rounded to nearest hundredth

   rsAgeEval:  25 * 2 - 3 + 3 + 2 / 2 = 51
   * RoadHacker found this sign at the age of 51 years young.

   rs42Eval:  25 * 2 * (3 - 2) - 2^3 = 42
   * 42 is the "Answer to Life, the Universe, and Everything"
