BARS::16 Miles From Florence on AZ Hwy-79 in Arizona

This road sign is on southbound AZ Hwy-79 in Arizona. The picture was taken on 15 March 2013.

The road sign says...

   +------------------+
   | Florence      16 |
   | Tucson        83 |
   +------------------+
   the numbers are:  16  83

   rsHwyEval:  83 - sqrt(16) = 79
   * This road is on southbound AZ Hwy-79.

   PrimeAndSquareRS:  16 is a square number; 83 is a prime number

   note:  83 is a "cousin prime" with prime number 79 
          and this road sign is on AZ Hwy79.

   off-by-one rsCardinality:  83 % sqrt(sqrt(16)) = 2-1
   * There are two numbers in this road sign.

   off-by-one rsCardinality:  sqrt(sqrt(83 - sqrt(sqrt(16)))) = 2+1
   * There are two numbers in this road sign.

   BARSfunc math:  sqrt(16)! = mult_digits(83)
   * mult_digits(n) = product of the digits of n
     domain:  n must be a prime number
   * 83 is prime; mult_digits(83) = 8*3 = 24

   BARSfunc rsCardinalityEval:  cuberoot(16 + sum_digits(83)) = 3
   * sum_digits(n) = sum the digits of n
     domain:  n must be a prime number
   * 83 is prime; sum_digits(83) = 8+3 = 11

   off-by-one BARSfunc rsAgeEval:  16 + reverse_digits(83) = 55-1
   * RoadHacker was 55 years young when he found this road sign.
   * reverse_digits(n) = the digits of n reversed
     domain:  n must be a prime number
   * 83 is prime; reverse_digits(83) = 38
