BARS::Hwy-89 and Hwy-180 Jct. in Arizona

These road signs were found by ColletteC during the spring 2009 semester.

The road signs say...

   +----------------------------------------+ +------------+
   | Business I-40  US-180            US-89 | | Highway 89 |
   | Flagstaff                         Page | +------------+
   | Grand Canyon              Grand Canyon |
   | South Rim  78            South Rim  79 |
   |                          North Rim 195 |
   +----------------------------------------+
   the numbers are:  40  180  78  89  79  195  89

   the math is:  195 + 180 - 89 - 89 - 79 - 78 = 40

   more math:  40 / (89 - 79) + 89 - 78 + 180 = 195

   observe... 195 - 180 + 79 - 78 = 16; sqrt(16) = 4; sqrt(4) = 2

   rs42Eval:  sqrt(sqrt(195 - 180 + 79 - 78)) + 89 - 89 + 40 = 42
   * 42 is the "Answer to Life, the Universe, and Everything"

   rsAgeEval:  sqrt(sqrt(195 - 180 + 79 - 78)) + sqrt(89 * 89) - 40 = 51
   * MathBabbler was 51 years young when he found this equation
