### BARS::2 Miles North of Sunset Point Rest Area on I-17 in Arizona

This road sign is on southbound I-17 two miles north of the Sunset Point Rest Area in Arizona. [Note: The picture of the road sign was taken from a Greyhound bus.]

The road sign says...

```   +-------------------------+
| Rest Area             2 |
| Black Canyon City    12 |
| Phoenix              56 |
+-------------------------+
```
```   the numbers are:  2  12  56

the math is:  cuberoot(56 % 12) = 2

rs42Eval:  56 - 12 - 2 = 42
* 42 is the "Answer to Life, the Universe, and Everything"

BARSfunc rsPiEval:  (56 - 12) / (2 + dup(12)) ~= Pi
* 22/7 approximates Pi (3.14) rounded to nearest hundredth
* dup(n) = n  is used to duplicate a specific number

BARSfunc rsAgeEval:  56 - defactorial(12 / 2) = 53
* RoadHacker was 53 years young when he found this road sign.
* defactorial(n) = m  implies  m! = n
* defactorial(6) = 3  because  3! = 6

BARSfunc off-by-one rsAgeEval:  56 - defactorial(2 * 12) = 53-1
* RoadHacker was 53 years young when he found this road sign.
* defactorial(24) = 4  because  4! = 24
