   the numbers are:  85  1  70  15  2  3

   the math is: 85 - 70 - 15 = 3 - 2 - 1

   more math:  (85 % (70 % 15) + 1) / 2 = 3
   
   rsPhiEval:  (1 + sqrt(sqrt((85 - 70) * 15) / 3)) / 2 = Phi
   * Phi is the golden ratio and it approximates 1.61803399

   rsCardinalityEval:  (85 - 70) / 15 - 1 + 2 * 3 = 6
   * There are six numbers in this road sign.

   rsStateEval:  (85 - 70) / 15 + 1 + 2 + 3 = 7
   * Maryland was the 7th state admitted to the Union.

   rs37Eval:  85 - 70 + 15 + 3! + 2 - 1 = 37
   * Why rs37Eval? 37 Heaven @ http://thirty-seven.org

   rs42Eval:  85 - 70 + 15 + (1 + 2)! + 3! = 42
   * 42 is the "Answer to Life, the Universe, and Everything"

   rsAgeEval:  (85 - 70 + 15) * 2 - 3 - 1 = 56
   * MathBabber was 56 years young when he found this equation.

   off-by-one rsHwyEval:  70 * (2 + 3) - 85 + sqrt(1 + 15) = 270-1
   * This road sign is on I-270.
