The road sign says...

   +--------------------+
   | Solana Beach     1 |
   | Oceanside       17 |
   | Los Angeles    105 |
   +--------------------+
   the numbers are:  1  17  105

   rsCardinalityEval:  1 * (105 % 17) = 3
   * There are three numbers is this road sign.

   ... BARSfunc playground ...

   105 is a composite number

   spf(105) = 3+5+7 = 15
   * spf(n) = the sum of the prime factors of n
     domain: n must be a composite number

   spd(105) = 1+3+5+7+15+21+35 = 87
   * spd(n) = the sum of the proper divisors of n
     domain: n must be a composite number

   17 is a prime number

   reverse_digits(17) = 71  [note: 71 is prime]
   * reverse_digits(n) = the digits of n reversed
     domain:  n must be a prime number

   mult_digits(17) = 1*7 = 7
   * mult_digits(n) = product of the digits of n
     domain:  n must be a prime number

   sum_digits(17) = 1+7 = 8
   * sum_digits(n) = sum the digits of n
     domain:  n must be a prime number

   BARSfunc rsStateEval:  spf(105) + 17 - 1 = 31
   * California was the 31st state admitted to the Union.
     sum_digits(17) = 

   BARSfunc math:  105 % sum_digits(17) = 1

   BARSfunc math:  (105 % mult_digits(17))! = 1

   off-by-one BARSfunc math:  17 - 1 = spf(105)+1
