The street sign says...

```   +--------------+
| 2 HR Parking |
| 9 am to 5 pm |
+--------------+
```
```   the numbers are:  2  9  5

the math is:  sqrt(9 - 5) = 2

more math:  5 - sqrt(9) = 2

rsAgeEval:  sqrt(9)! * 5 * 2 = 60
* RoadHacker was 60 years young when he found this parking sign.

rs42Eval:  5! / sqrt(9) + 2 = 42
* 42 is the "Answer to Life, the Universe, and Everything"

rsCardinalityEval:  (2 * 9) % 5 = 3
rsCardinalityEval:  sqrt(9)! - 5 + 2 = 3
* There are three numbers in this street sign.

off-by-one rsStateEval:  sqrt(9)! * 5 + 2 = 33-1
* Oregon was the 33rd state admitted to the Union.

off-by-one rs42Eval:  2^5 + 9 = 42-1
off-by-one rs42Eval:  5 * 9 - 2 = 42+1
* 42 is the "Answer to Life, the Universe, and Everything"

BARSfunc off-by-one rsStateEval:  spf(9) * 5 + 2 = 33-1
* Oregon was the 33rd state admitted to the Union.
* spf(n) = the sum of the prime factors of n
domain: n must be a composite number
* 9 is composite; spf(9) = 3+3 = 6
