BARS::Approaching Center Parkway Exit in Tempe, Arizona

This road sign was found on eastbound Loop 202 approaching Tempe, Arizona.

The road sign says...

   +--------------------------------+
   | Priest Dr - Center Pkwy    1/4 |
   | Scottsdale Rd            2 1/4 |
   | McClintock Dr            3     |
   +--------------------------------+

   the numbers are:  (1/4)  (2 1/4)  3

   the math is:  sqrt((2 1/4) / (1/4)) = 3

   observe...
      2 1/4 = 9/4
      9/4 ÷ 1/4 = 9/4 x 4/1 = 9
      sqrt(9) = 3

   more math is:  sqrt(2 1/4) = sqrt(1/4) x 3

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