BARS::AZ Hwy-87 21 Miles South of Winslow, Arizona

This road sign was found on AZ Hwy-89 twenty-one miles south of Winslow, Arizona.

The road sign says...

   +----------------+
   | Winslow     21 |
   | Jct I-40    25 |
   +----------------+

   the numbers are:  I  40  21  25

   the math is:  log(40 / (25 - 21)) = I

   observe...
      I is Roman numeral one

   off-by-one math:  (21+1) / ((40 / sqrt(25))-1) = 22 / 7 = pi

Note: RoadSignMath.com does not use roman numerals nor do they allow the use of the log() function.
