### 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.

```   +------------------+
| 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
