### BARS::8 Miles From Coolidge on AZ Hwy-87 in Arizona

This road sign is on southbound AZ Hwy-87 in Arizona.

The road sign says...

```   +-----------------+
| Coolidge      8 |
| Florence     17 |
| Picacho      27 |
+-----------------+
```
```   the numbers are:  8  17  27

the math is:  sqrt(17 - 8) = cuberoot(27)

rsCardinalityEval:  log(27 - 17) + cuberoot(8) = 3
* There are 3 numbers in this road sign.

rsCardinalityEval:  27 / (17 - 8) = 3
* There are 3 numbers in this road sign.

rsCardinalityEval:  cuberoot(27) * 17 % 8 = 3
* There are 3 numbers in this road sign.

rs42Eval:  27 + 17 - cuberoot(8) = 42
* 42 is the "Answer to Life, the Universe, and Everything"

number system rs42Eval:  178 + 27 = 42
* 42 is the "Answer to Life, the Universe, and Everything"

BARSfunc rs42Eval:  27 + mult_digits(17) + 8 = 42
* mult_digits(n) = product of the digits of n
domain:  n must be a prime number
* mult_digits(17) = 1*7 = 7

BARSfunc rs42Eval:  reverse_digits(17) - 27 - cuberoot(8) = 42
* reverse_digits(n) = the digits of n reversed
domain:  n must be a prime number
* reverse_digits(17) = 71

BARSfunc rsAgeEval:  cuberoot(27)! * 8 + sum_digits(17) = 56
* RoadHacker was 56 years young when he found this road sign.
* sum_digits(n) = sum the digits of n
domain:  n must be a prime number
* sum_digits(17) = 1+7 = 8

off-by-one rs37Eval:  17 + 27 - 8 = 37-1
* Why rs37Eval? 37 Heaven @ http://thirty-seven.org

off-by-one rs42Eval:  cuberoot(27) * 8 + 17 = 42-1
