BARS::Raton I-25 Exits Sign Seen From Amtrak Southwest Chief

This Raton exits sign was on southbound I-25 near Raton, New Mexico.

The Raton exits sign says...

   +----------------------+
   |  Raton Next 4 Exits  |
   | Travelers Facilities |
   | 21 Modern Stations   |
   | 25 Restaurants       |
   | 21 Motels            |
   | 2 Campgrounds        |
   +----------------------+
   the numbers are:  4  21  25  21  2

   the math is:  sqrt(25) + 21 / 21 - 2 = 4

   more math:  21 / 21 * 2 = log(4 * 25)

   rsPhiEval:  (21 / 21 + sqrt(sqrt(25))) / (4 - 2) = Phi
   * Phi is the golden ratio and it approximates 1.61803399

   rsCardinalityEval:  (21 % 4) * (21 % 2) * sqrt(25) = 5
   * There are five numbers in this sign.

   rsStateEval:  25 * 2 - 4 + 21 / 21 = 47
   * New Mexico was the 47th state admitted to the Union.

   rs42Eval:  21 + 21 * (4 - cuberoot(25 + 2)) = 42
   * 42 is the "Answer to Life, the Universe, and Everything"

   rs37Eval:  21 + 21 - cuberoot(25 + 2) - sqrt(4) = 37
   * Why rs37Eval? 37 Heaven @ http://thirty-seven.org

   BARSfunc rsPiEval:  (21 + 21 + 2) / (4 + spf(25)) ~= Pi
   * 22/7 approximates Pi rounded to nearest hundredth (3.14)
     π ~= 3.14159265358979323846264338327950
   * spf(n) = the sum of the prime factors of n
     domain: n must be a composite number
   * 25 is composite; spf(25) = 5+5 = 10

   off-by-one rsAgeEval:  21 + 25 + 21 - 4 - 2 = 60+1
   * MathBabbler was 60 years young when he found this equation.
