BARS::Half-Mile From Sky Harbor on I-17 in Phoenix, Arizona

These road signs were found on southbound I-17 one-half mile from Sky Harbor Intl. Airport in Phoenix, Arizona.

The road signs say...

   +------------+ +-----------+
   |  Exit 194  | | Exit 195A |
   |  10  West  | |           |
   | Sky Harbor | |  16th St  |
   |  1/2 Mile  | |           |
   +------------+ +-----------+

   the numbers are:  10  (1/2)  16  194  195

   the math is:  1/2 x 10 - sqrt(16) + 194 = 195

   observe...
      1/2 x 10 = .5 x 10 = .5
      .5 x 10 = 5
      sqrt(16) = 4
      5 - 4 = 1
      1 + 194 = 195

   [more math added on 28 April 2007 after driving home 
    from a P-10 math meeting in downtown Phoenix]

   more math: (195 + log(10) - 194) / (1/2) = sqrt(16)

   observe...
      log(10) = 1
      2 / (1/2 = 2 x 2 = 4
      sqrt(16) = 4
