BARS::Nearing AZ Hwy-80 in Benson, Arizona

This road sign is the eastbound I-10 off-ramp for Benson, Arizona.

The road sign says...

   +--------------------+
   | AZ Hwy-80 East   2 |
   | Bisbee          51 |
   | Douglas         76 |
   +--------------------+
   the numbers are:  80  2  51  76

   rsAgeEval:  51 + sqrt(80 - 76) / 2 = 52
   * RoadHacker was 52 years young when he found this road sign.

   rsStateEval:  51 - avg(2, 80 - 76) = 48
   * Arizona was the 48th state admitted to the Union.

   rsTweetLenEval:  80 + sqrt(76 - 51)! / 2 = 140
   * 140 is the maximum length of a Twitter posting (tweet).

   observe...
      76 - 51 = 25; sqrt(25) = 5; 5! = 120
      80 + 120 / 2 = 80 + 60 = 140

   off-by-one math:  cuberoot(51 - (80 - 76)!) = 2 + 1

   observe...
      80 - 76 = 4; 4! = 24; 51 - 24 = 27; cuberoot(27) = 3

   spf(n) = the sum of the prime factors of n

   spf(80) = 13; spf(76) = 23; spf(51) = 20

   BARSfunc math:  2 * (spf(76) - spf(80)) = spf(51)
