BARS::17 Miles From Needles in California

This road sign is off of US Hwy-95 in California.

The road sign says...

   +--------------------------+
   | <- Searchlight        36 |
   | <- Las Vegas          91 |
   |    Needles         17 -> |
   +--------------------------+
   the numbers are:  36  91  17

   the math is:  91 % 17 = sqrt(36)

   BARSfunc rsStateEval:  reverse(spf(36) + spf(91) - 17) = 31
   * California was the 31st state admitted to the Union.
   * spf(n) = the sum of the prime factors of n
   * spf(36) = 2+2+3+3 = 10
   * spf(91) = 7+13 = 20
   * reverse_digits(n) = the digits of n reversed
     domain:  n must be a prime number

   note:  91 is not prime and the reverse_digits(n)
          BARS function is defined for prime numbers
          only; however, 91 is semi-prime (i.e. it
          has only two prime factors) and an exception
          is being made for the following equation.

   BARSfunc math:  17 + reverse_digits(91) = 36
