BARS::Rural Iowa on IA Hwy-2

These street signs were seen at the Little Flock Chapel located on Iowa Highway-2 in rural Iowa west of Centerville.

The street signs say...

   +--------------+
   | <- 108th Ave |
   +--------------+
   |     Hwy 2    |
   +--------------+
   | 110th Ave -> |
   +--------------+
   the numbers are:  108  2  110

   the math is:  108 + 2 = 110

   more math:  110 % 108 = 2

   spf(108) = 2+2+3+3+3 = 13
   spf(110) = 2+5+11 = 18
   * spf(n) = the sum of the prime factors of n
     domain: n must be a composite number
     108 and 110 are both composite numbers

   BARSfunc rsCardinalityEval:  spf(110) - spf(108) - 2 = 3
   * There are three numbers in these street signs.

   BARSfunc rsStateEval:  spf(110) + spf(108) - 2 = 29
   * Iowa was the 29th state admitted to the Union.
