BARS::Castle Hot Springs Road in Arizona

This road sign is on Castle Hot Springs Road in Arizona. MathBabbler found this road sign while reading the Arizona Republic on 6 April 2013 and his picture of the road is a picture of a picture.

The road sign says...

   +-----------------------------+
   | <- Castle Hot Springs Rd -> |
   | <- State Route 74     16 Mi |
   | <- Lake Pleasant      10 Mi |
   | Morristown        21 Mi  -> |
   +-----------------------------+
   the numbers are:  74  16  10   21

   rsPiEval:  (74 - 10 + sqrt(sqrt(16))) / 21 ~= Pi
   * 66/21 approximates Pi rounded to nearest hundredth (3.14)
   * 3.1415926535897932384626

   rs37Eval:  21 % 10 * (74 / sqrt(sqrt(16))) = 37
   * Why rs37Eval? 37 Heaven @ http://thirty-seven.org

   rs42Eval:  log(74 + 16 + 10) * 21 = 42
   * 42 is the "Answer to Life, the Universe, and Everything"

   rs42Eval:  cuberoot(sqrt(74 - 10)) * 21 = 42
   * 42 is the "Answer to Life, the Universe, and Everything"

   number system rs42Eval:  74 - 2116 + log(10) = 42
   * 42 is the "Answer to Life, the Universe, and Everything"

   rsAgeEval:  74 - 21 + log(10) * sqrt(sqrt(16)) = 55
   * MathBabbler was 55 years young when he created this BARS.

   BARSfunc math:  reverse_digits(16 + 10 + 21) = 74
   * reverse_digits(n) = the digits of n reversed
     domain:  n must be a prime number
   * 47 is prime; reverse_digits(16 + 10 + 21) = 74

   off-by-one rsStateEval:  74 - 21 + 10 - 16 = 48-1
   * Arizona was the 48th state admitted to the Union.
