BARS::Upcoming Exits on Eastbound I-40 Albuquerque, New Mexico

This road sign was found on eastbound I-40 on Pi Day 2007 in Albuquerque, New Mexico.

The road sign says...

   +-----------------------+
   | 8th-6th St      1 1/2 |
   | 4th-2nd St      1 3/4 |
   | University Blvd       |
   +-----------------------+
   the numbers are:  2  4  6  8  (1 1/2)  (1 3/4)

   the math is:  (1 3/4 - 1 1/2) * 4 * (6 + 2) = 8

   observe...
      1 3/4 - 1 1/2 = 1/4
      1/4 * 4 = 1
      1 * (6 + 2) = 1 * 8 = 8

   [solve for 'n']  (1 3/4 - 1 1/2) * 4 * (n + 2) = 8
Update::2009.10.09

This BARS was selected to be one of the BARS of the Week for week #8 of the fall 2009 semester.


   the numbers are:  2  4  6  8  (1 1/2)  (1 3/4)

   combine the two mixed numbers:  1 3/4 - 1 1/2 = 1/4

   the numbers are:  2  4  6  8  1/4

   rsAgeEval:  8 * 6 + 4 * sqrt(1/4) + 2 = 52
   * MathBabbler was 52 years young when he found this equation.

   rsAgeEval:  8 * 6 + 2 - 1/4 * 4 = 49
   * RoadHacker was 49 years young when he found this road sign.

   rsStateEval:  8 * 6 - 2 / sqrt(1/4) / 4 = 47
   * New Mexico was the 47th state admitted to the Union.

   rs42Eval:  8 * 6 - sqrt(4 / (1/4)) - 2 = 42
   * 42 is the "Answer to Life, the Universe, and Everything"

   rsHwyEval:  8 * 6 - 4 - 2 / sqrt(1/4) = 40
   * This road sign is on I-40.

   rsPhiEval:  sqrt(1/4) + (sqrt((cuberoot(8) + 6 / sqrt(4))) / 2) = Phi
   * Phi is the golden ratio and it approximates 1.61803399

   rsPiEval:  (4! - cuberoot(8)) / (6 + 2 * sqrt(1/4)) = Pi
   * 22/7 approximates Pi (3.14) rounded to nearest hundredth

   rsPiEval:  (4! - sqrt(2 / sqrt(1/4))) / avg(6, 8) = Pi
   * 22/7 approximates Pi (3.14) rounded to nearest hundredth

   rsPiEval:  (8 + 2) * (4! - (6 * sqrt(1/4))!) degrees = Pi radians
   * 180 degrees equals Pi radians

   Note: These are special rsPiEvals because this 
         road sign was found in Pi Day 2007.
