BARS::200 W. 1st St. and 100 S. Farmer Ave. in Tempe, Arizona

These street signs are at 200 W. 1st St. and 200 S. Farmer Ave. in Tempe, Arizona.

The street signs say...

   +---------------------+
   | W 1st St     200 -> |
   -----------------------
   | S Farmer Ave <- 100 |
   +---------------------+
   the numbers are:  1  200  100

   the math is:  log(sqrt(200 - 100)) = 1

   rsPiEval:  sqrt(200) - sqrt(100) - 1 = 3.14213562

   observe...
      3.14213562 rounded to nearest thousandth = 3.142
      Pi = 3.14159265
      3.14159265 rounded to nearest thousandth = 3.142
      22/7 = 3.14285714
      3.14285714 rounded to nearest thousandth = 3.143

   more math:  log(sqrt(100)) = 10^1

   off-by-one math:  200 / 100 = 1 + 1

   rsAgeEval:  200 / 1002 + 1 = 51
