BARS::Duiven Exit in Germany

This road sign is from Germany and it was submitted by SCC student Sabrina during the fall 2009 semester.

The road sign says...

   +--------------------+
   | A12 Westervoort  2 |
   |    A28 Duieven     |
   |    Centerpoort     |
   |        300 m       |
   +--------------------+
   the numbers are:  12  2  28  300

   rsAgeEval:  (300 % 28) * 2 + 12 = 52
   * MathBabbler was 52 years young when he found this equation.

   rs42Eval:  summation(12, 28) - 300 + 2 = 42
   * 42 is the "Answer to Life, the Universe, and Everything"

   off-by-one math:  300 / 12 + 2 = 28 - 1

   off-by-one BARSfunc math:  defactorial(sqrt(12 * 28 - 300)) = 2 + 1

   observe...
      12 * 28 = 336: 336 - 300 = 36; sqrt(36) = 6
      defactorial(6) = 3 because 3! = 6

   off-by-one BARSfunc math:  spf(300) - spf(12) + 2 = spf(28) + 1

   observe...
      spf(n) = the sum of the prime factors of n
      spf(12) = 7; spf(28) = 11; spf(300) = 17

   playground...
      300 + 12 * 2 = 324; sqrt(324) = 18
