BARS::Cochiti Road Sign on Pi Day 2007 in New Mexico

This road sign was found along square numbered NM Hwy-16 on Pi Day 2007 in New Mexico.

The road sign says...

   +--------------------+
   | Pena Blance      9 |
   | Cochiti Lake    12 |
   | Cochita Pueblo  13 |
   | Cochita Lake       |
   | Golf Course     15 |
   +--------------------+
   the numbers are:  9  12  13  15

   the math is:  sqrt(12 + 13) * sqrt(9) = 15

   observe...
      12 + 13 = 25
      sqrt(25) = 5
      sqrt(9) = 3
      5 * 3 = 15

   rsHwyEval:  (15 + 12) / 9 + 13 = 16
   The road sign was found on NM Hwy-16.

   rsAgeEval:  9 + 12 + 13 + 15 = 49
   The road sign was found when MathBabbler was 49 years young.

   more math:  sqrt(12 / sqrt(9)) + 13 = 15

   observe...
      sqrt(9) = 3
      12 / 3 = 4
      sqrt(4) = 2
      13 + 2 = 15

   more math:  12 / sqrt(9)! + 13 = 15

   observe...
      sqrt(9) = 3
      3! = 6
      12 / 6 = 2
      2 + 13 = 15

   off-by-one math:  12 - 9 + 13 = 15 + 1
   off-by-one math:  sqrt(15 + 13 - 12) = sqrt(9) + 1
   off-by-one math:  sqrt(12 + 13) + 9 = 15 - 1
