### BARS::Next Service 47 Miles; 1 Mile From Joshua Tree National Park

This road sign is one mile from Joshua Tree National Park in California.

The road sign says...

```   +---------------------------+
| Joshua Tree Natl Park   1 |
| Cottonwood Springs      8 |
| Twentynine Palms       47 |
+---------------------------+
| Next Service 47 Miles     |
+---------------------------+
```
```   the numbers are:  1  8  47  47

the math is:  47 / 47 + 1 = cuberoot(8)

rsAgeEval:  (47 + 1)! / 47! + cuberoot(8) = 50
* RoadHacker was 50 years young when he found this road sign.

rsCardinalityEval:  47 / 47 + cuberoot(8) + 1 = 4
* There are four numbers in these signs.

off-by-one rs42Eval:  47 - 47 % 8 + 1 = 42-1
* 42 is the "Answer to Life, the Universe, and Everything"

BARS functions for prime numbers...
* mult_digits(n) = product of the digits of n
domain:  n must be a prime number
* sum_digits(n) = sum the digits of n
domain:  n must be a prime number
* 47 is prime; mult_digits(47) = 4*7 = 28
* 47 is prime; sum_digits(47) = 4+7 = 11

BARSfunc rsAgeEval:  mult_digits(47)+mult_digits(47)+cuberoot(8)*1 = 58
* MathBabbler was 58 years young when he found this equation.

BARSfunc rsAgeEval:  sum_digits(47 - 8 * 1 + 47 = 50
* RoadHacker was 50 years young when he found this road sign.

BARSfunc rs37Eval:  47 - sum_digits(47) + cuberoot(8) - 1 = 37
* Why rs37Eval? 37 Heaven @ http://thirty-seven.org
