### BARS::Street Signs in Old Bisbee, Arizona

These street signs are in Bisbee, Arizona.

The street signs say...

```+---------------------+
| Speed Limit       5 |
-----------------------
| Speed Limit      15 |
-----------------------
| Weight Limit 4 Tons |
+---------------------+
```
```   the numbers are:  4  5  15

the math is:  cuberoot(5! / 15) = sqrt(4)

rsStateEval:  4! * cuberoot(5! / 15) = 48
* Arizona was the 48th state admitted to the Union.

rsCardinalityEval:  15 / (5! / 4!) = 3
rsCardinalityEval:  4 - log(15 - 5) = 3
rsCardinalityEval:  (15 / 5)! / sqrt(4) = 3
* There are 3 numbers in these signs.

BARSfunc rs37Eval:  spf(15) * 4 + 5 = 37
* Why rs37Eval? 37 Heaven @ http://thirty-seven.org
* spf(n) = the sum of the prime factors of n
domain: n must be a composite number
* spf(15) = 3+5 = 8

BARSfunc rs42Eval:  spf(15) * 5 + sqrt(4) = 42
* 42 is the "Answer to Life, the Universe, and Everything"

off-by-one rsStateEval:  sqrt(4)^5 + 15 = 48 - 1
* Arizona was the 48th state admitted to the Union.
