BARS::Approaching Recker Road on Loop 202 in Mesa, Arizona

This road sign is on westbound Loop 202 (Red Mountain Freeway) in Mesa, Arizona.

The road sign says...

   +--------------------------+
   | McKellips Rd       1     |
   | McDowell Rd        2 1/4 |
   | Recker Rd          4     |
   +--------------------------+
   the numbers are:  1  (2 1/4)  4)

   the math is:  avg(1, sqrt(4)) = sqrt(2 1/4)

   observe...
      sqrt(4) = 2
      avg(1, 2) = 1.5 = sqrt(2 1/4)

   more math:  sqrt(2 1/4) - 1  = reciprocal(sqrt(4))

   observe...
      sqrt(2 1/4) = sqrt(9/4) = sqrt(9)/sqrt(4) = 3/2 = 1.5
      1.5 - 1 = 0.5
      sqrt(4) = 2
      reciprocal(2) = 1/2 = 0.5

   more math:  sqrt(2 1/4) - 1  = sqrt(reciprocal(4))

   observe...
      reciprocal(4) = 1/4
      sqrt(1/4) = sqrt(1)/sqrt(4) = 1/2 = 0.5
