BARS::Salt River Canyon Rest Area Along US Hwy-60

This road sign is located along US Hwy-60 near the Salt River Canyon rest area.

The road sign says...

    +-----------------------+
    | <- Cibecue Creek    4 |
    | <- Salt Bank        7 |
    | <- Canyon Creek    16 |
    | <- Medecine Ranch  21 |
    | <- Gleason Flats   26 |
    | <- Camp Grounds       |
    +-----------------------+
    the numbers are: 4  7  16  21  26

    the math is: 21 + 16 - 7 - 4 = 26

    [solve for 'n']  21 + 16 - n - 4 = 26

This road sign was submitted to RoadSignMath.com on 18 March 2006.

Update::2008.02.08

This BARS was re-evaluated to see if this road sign was a Pi BARS. Keying off of the number 7, the following Pi math was discovered.

   ((21 - (26 - 16)) * sqrt(4)) / 7 = Pi 
   * 22/7 approximates Pi rounded to nearest hundredth (3.14)

   observe...
      22 / 7 = 3.14285714
          Pi = 3.14159265

   [solve for 'n]  ((21 - (26 - n)) * sqrt(4)) / 7 = 3.14
Update::2014.05.03

This BARS was re-evaluated when RoadHacker decided he was going to revisit this road sign and make a video for this BARS. The BARS system has evolved since this BARS was created back on 18 March 2006.

   the numbers are: 4  7  16  21  26

   more math:  21 / 7 + log(26 - 16) = 4

   more math:  26 - 7 + sqrt(16) / sqrt(4) = 21

   more math:  sqrt(16 - 7) + sqrt(4) + 21 = 26

   rsPiEval:  (26 + 16 + sqrt(4)) / (21 - 7) = Pi
   * 44/14 approximates Pi rounded to nearest hundredth (3.14)

   rsPhiEval:  (7 % sqrt(sqrt(16)) + sqrt(26 - 21)) / sqrt(4) = Phi
   * Phi is the golden ratio and it approximates 1.61803399

   rsHwyEval:  21 + 26 + 7 + 4 + sqrt(sqrt(16)) = 60
   * This road sign is just off of US Hwy-60.

   rsAgeEval:  21 + 26 + 7 + sqrt(16 / 4) = 56
   * MathBabbler was 56 years young when he found this equation.

   rsStateEval:  21 + 26 + 16 / sqrt(4) - 7 = 48
   * Arizona was the 48th state admitted to the Union.

   rsAgeEval:  4 * 7 + (26 - 21) * sqrt(16) = 48
   * RoadHacker was 48 years young when he found this road sign.

   rs42Eval:  21 - 16 + 26 + 4 + 7 = 42
   * 42 is the "Answer to Life, the Universe, and Everything"

   rs37Eval:  21 / 7 + 26 - 16 + 4! = 37
   * Why rs37Eval? 37 Heaven @ http://thirty-seven.org

   rsCardinalityEval:  sqrt((26 - 21) * (16 - 7 - 4)) = 5
   * There are 5 numbers in this road sign.
