Update::2009.02.11

This BARS was selected to be one of the BARS of the Week for week #5 of the spring 2009 semester.

   the numbers are:  5  7  3  4

   rsPhiEval:  (log(7 + 3) + sqrt(5)) / 2 = Phi
   * Phi is the golden ratio and it approximates 1.61803399

   rs42Eval:  5 * 7 + 3 + 4 = 42
   * 42 is the "Answer to Life, the Universe, and Everything"

   rsAgeEval:  (7! / 5!) + 3 + 4 = 49
   * RoadHacker was 49 years young when he found this road sign.

   rsAgeEval:  5! / 3 + 7 + 4 = 51
   * MathBabbler was 51 years young when he inserted this equation.

   more math:  3! + log(sqrt(4) * 5) = 7

   off-by-one math:  7 + 3 - 5 = 4 + 1

   off-by-one math:  sqrt(5 + 4) + 3 = 7 - 1

   [solve for 'log(sqrt(4) * 5)']  3! + log(sqrt(4) * 5) = 7
