BARS::Speed Humps in Tempe, Arizona

This sign collection was found in Tempe's Maple Ash neighborhood.

Top sign: Diamond-shaped yellow warning sign saying "Speed Humps 20mph"

Middle sign: Rectangular-shaped yellow sign saying "Next 1600ft"

Bottom sign: Rectangular-shaped white restricted parking sign saying "restricted parking, area 2, resident permit parking only, 24 hour, Monday thru Saturday."

   the numbers are:  20  1600  24  2

   the math is: sqrt(20 - (sqrt(1600) - 24)) = 2

   observe...
      sqrt(1600) = 40
      40 - 24 = 16
      20 - 16 = 4
      sqrt(4) = 2

   more math: sqrt(sqrt(20 - sqrt(sqrt(1600) - 24))) = 2

      sqrt(sqrt(20 - sqrt(40 - 24)))
      sqrt(sqrt(20 - sqrt(16)))
      sqrt(sqrt(20 - 4))
      sqrt(sqrt(16))
      sqrt(4) = 2

   [solve for 'n']  sqrt(20 - (sqrt(1600) - n)) = 2
