BARS::17 Miles From San Carlos on US Hwy-70 in Arizona

This road sign is on eastbound US Hwy-70 in Arizona. The road sign picture was taken on Pi Day 2008.

The road sign says...

   +-----------------+
   | San Carlos   17 |
   | Safford      74 |
   +-----------------+
   the numbers are:  17  74

   split_into_squares_sum(74) = { 25, 49 }

   the numbers become:  17  25  49

   Pi math:  (17 + sqrt(25)) / sqrt(49) = Pi (3.14)

   observe... 
      sqrt(25) = 5
      17 + 5 = 22
      sqrt(49) = 7
      22 / 7 = 3.14285714
          Pi = 3.14159265

   off-by-one math:  25 - 17 = sqrt(49) + 1

   sum_prime_number_digits(17) = 8
   split_into_squares_sum(8) = { 4, 4 }

   the numbers become:  4  4  25  49

   the math is:  (sqrt(4) + sqrt(4))! = 49 - 25

   observe...
      sqrt(4) = 2
      2 + 2 = 4
      4! = 24  [4 * 3 * 2 * 1]

Note: This road sign was photographed on Pi Day 2008.
