BARS::Electronic Sign on Westbound I-10 in Tempe, Arizona

This electronic road sign was seen on westbound I-10 in Tempe, Arizona.

The road sign says...

   +--------------------+
   |     Minutes To     |
   | I-17  7th St    10 |
   | I-10  7th St    12 |
   +--------------------+
   the numbers are:  7  7  10  10  12  17

   the math is:  10 + 7 + 7 = (17 - 12 - log(10))!

   more math:  (sqrt(17 - log(10)) + 7 / 7)! / 10 = 12

   rsPhiEval:  (log(10) + sqrt(12 - 7)) / (log(10) + log(17 - 7)) = Phi
   * Phi is the golden ratio and it approximates 1.61803399

   rsPiEval:  (10 + 12 * (17 - 7) / 10) / 7 = Pi
   * 22/7 approximates Pi rounded to nearest hundredth (3.14)
   * 3.1415926535897932384626

   rsStateEval:  (17 % 7)! * (12 - 10)^(10 - 7) = 48
   * Arizona was 48th state admitted to the Union.

   off-by-one rsAgeEval:  7 * 10 - 10 - 7 + (12 - 7) = 57-1
   off-by-one rsAgeEval:  cuberoot(7+log(10))*(12/cuberoot(10+17)*7 = 57+1
   off-by-one rsAgeEval:  (7 + 10 + 12) * (log(10) + log(17 - 7)) = 57+1
   * TempeHiker was 57 years young when he saw this electronic sign.

   rsModeEval:  mod(17 - 10, 7, 12 - 10) = 7
   rsRangeEval:  range(7 , 7, 10, 12, 17) = 10
