BARS::Approaching 6th Ave. on I-10 East in Tucson, Arizona

This road sign is on eastbound I-10 in downtown Tucson, Arizona.

The road sign says...

   +--------------------+
   | 6th Ave            |
   | 4th Ave        1/4 |
   | Benson Hwy         |
   | Park Ave       3/4 |
   +--------------------+
   the numbers are:  6  4  (1/4)  (3/4)

   the math is: 6 / (3/4) * sqrt(1/4) = 4

   observe...
      6 / (3/4) = 6 * (4/3) = 24/3 = 8
      sqrt(1/4) = sqrt(1) / sqrt(4) = 1/2
      8 * 1/2 = 8/2 = 4

   more math:  log(6 + 4) - (1/4) = (3/4)

   observe...
      log(6 + 4) = log(10) = 1
      1 - (1/4) = (3/4)

   more math:  6 / sqrt(4) * (1/4) = (3/4)
   
   observe...
      sqrt(4) = 2
      6 / 2 = 3
      3 * 1/4 = 3/4

   [exercise]  solve for 'n':  6 / (n/4) * sqrt(1/4) = 4

   [exercise]  solve for 'n':  6 / n * (1/4) = (3/4)
