BARS::113 Miles From Death Valley in Baker, California

This road sign is on CA Hwy-127 in Baker, California.

The road sign says...

   +------------+
   | CA Hwy-127 |
   +------------------+
   | Shoshone      56 |
   | Death Valley 113 |
   +------------------+
   the numbers are:  127  56  113

   rsHwyEval:  127 * (113 % 56) = 127
   * This road sign is on CA Hwy-127.

   BARSfunc math:  113 % 56 = log(sum_digits(127))

   BARSfunc rsAgeEval:  56 - mult_digits(113) - log(sum_digits(127)) = 52
   * RoadHacker was 52 years young when he found this road sign.

   BARSfunc off-by-one math:  127 - 113 = spf(56)+1

   ...BARS playground...

   56 is a composite number (i.e. it's not prime)

      * spf(n) = the sum of the prime factors of n
      * proper_divisors(n) = set of proper divisors of n
      * sum_proper_divisors(n) = sum of proper divisors of n

      spf(56) = 2+2+2+7 = 13
      proper_divisors(56) = { 1,2,4,7,8,14,28 }
      sum_proper_diviors(56) = 64

   127 and 113 are prime numbers

      * reverse_digits(n) = the digits of n reversed
      * sum_digits(n) = sum the digits of n

      reverse_digits(113) = 311 and 311 is prime
      sum_digits(113) = 5      
      mult_digits(113) = 3

      reverse_digits(127) = 721 and spf(721) = 7+103 = 110
      sum_digits(127) = 10     
      mult_digits(127) = 14
