   Love the sign! And welcome to Road Sign Math!

   This will get posted in a couple of weeks, 
   some other signs in front of you.
Update::2009.04.03

This BARS was selected to be one of the BARS of the Week for week #11 of the spring 2009 semester.

   the numbers are:  4  17  9  40  10

   previous math was:  4 + 17 + 9 + 10 = 40

   more math:  40 / 10 + 4 + 9 = 17

   rsPiEval:  (40 + 4) / (log(10) * (17 - sqrt(9))) = Pi
   * 44/14 approximates Pi (3.14) rounded to nearest hundredth

   rsPhiEval:  (log(10) + sqrt(40 / (17 - 9))) / sqrt(4) = Phi
   * Phi is the golden ratio and it approximates 1.61803399

   rsAgeEval:  40 + 17 - 9 + sqrt(4) + log(10) = 51
   * MathBabbler was 51 years young when he found this equation

   rsAgeEval:  17 * sqrt(9) + 40 / 10 - 4 = 51
   * MathBabbler was 51 years young when he found this equation

   rsAgeEval:  40 + (17 + sqrt(9)) / 10 * 4 = 48
   * RoadHacker was 48 years young when he found this road sign

   rs42Eval:  40 + 4 / (9 + 10 - 17) = 42
   * 42 is the "Answer to Life, the Universe, and Everything"

   rsHwyEval:  17 * 9 + 40 / 10 - 4 = 153
   * This road sign is on AZ Hwy-153

   rsHwyEval:  17 * sqrt(9) * defactorial(4! / (40 / 10)) = 153
   * This road sign is on AZ Hwy-153

   rsHwyEval:  17 * sqrt(9) * (log(10) + sqrt(sqrt(40 - 4!))) = 153
   * This road sign is on AZ Hwy-153

   more math:  (40 / (17 - 9)) - 4 = log(10)

   more math:  sqrt(40 + 9) - 4 = cuberoot(17 + 10)

   more math:  (sqrt(40 * 10) - 17) * sqrt(4) = sqrt(9)!

   [exercise]  17 * sqrt(9) * defactorial(4! / (40 / 10)) = 153
               What does  defactorial(4! / (40 / 10))  equal?
Update::2009.08.27

This BARS was selected to be one of the BARS of the Week for week #2 of the fall 2009 semester.

   the numbers are:  4  17  9  40  10

   rsAgeEval:  40 + 10 + (17 - 9) / 4 = 52
   * MathBabbler was 52 years young when he found this equation.

   rsStateEval:  40 - 10 + (17 - 9) / 4 = 48
   * Arizona was the 48th state admitted to the Union.
