BARS::Road Signs Seen on TV From Morgantown, West Virginia

These road signs (zoom) from Morgantown, West Virginia, were seen on TV.

The road signs say...

+--------------------+ +---------------------+ +-----------------+
|    North    West   | |   North      West   | |  To    South    |
| US Hwy-19 WV Hwy-7 | | US Hwy-119 WV Hwy-7 | | I-68 WV Hwy-119 |
+--------------------+ +---------------------+ +-----------------+
   the numbers are:  19  7  119  7  68  119

   the math is:  sqrt(119 / (119 / sqrt(68 - 19)) * 7) = 7

   rsPiEval:  (119 - 68 - 7) / (7 * log(119 - 19)) ~= Pi
   * 44/14 approximates Pi rounded to nearest hundredth (3.14)

   off-by-one rsStateEval:  68 / (7 / 7 + 19 / 19) = 35-1
   * West Virginia was the 35 state admitted to the Union.

   ... math playground...
   * 7 and 19 are prime numbers
   * spf(n) = the sum of the prime factors of n
   * spf(119) = 7+17 = 24; spf(68) = 21
