### BARS::Camp 4 at Yosemite National Park in California

This parking sign is at Camp 4 in the Yosemite National Park in California.

The parking sign says...

```   +----------------+
|      Camp 4    |
| Parking Permit |
|     Required   |
|    8pm to 6am  |
+----------------+
```
```   the numbers are:  4  8  6

the math is:  6 - 4 = cuberoot(8)

more math:  6 + sqrt(4) = 8

more math:  (4! / 8)! = 6

more math:  gcf(6, 8) = sqrt(4)

more math:  avg(4, 8) = 6

rsCardinalityEval:  6 / (8 / 4) = 3
* There are three numbers in this parking sign.

rsCardinalityEval:  6 / sqrt(cuberoot(8^sqrt(4))) = 3
* There are three numbers in this parking sign.

rsPiEval:  (6! / 8 * sqrt(4)) degrees = Pi radians

BARSfunc rsCardinalityEval:  4 - 6 / spf(8) = 3
* There are three numbers in this parking sign.
* spf(n) = the sum of the prime factors of n
domain:  n must be composite number
* 8 is a composite number; spf(8) = 2+2+2 = 6

BARSfunc rs42Eval:  spf(6) * 8 + sqrt(4) = 42
* 42 is the "Answer to Life, the Universe, and Everything"
* 6 is a composite number; spf(6) = 2+3 = 5

off-by-one rsStateEval:  4 * 6 + 8 = 31+1
* California was the 31st state admitted to the Union.

off-by-one rs37Eval:  4 * 8 + 6 = 37+1
off-by-one rs37Eval:  4! + 6 + 8 = 37+1
off-by-one rs37Eval:  6! / 4! + 8 = 37+1
* There was no official rs37Eval when this BARS was created;
* however, MathBabbler was considering adding it.
* Why add rs37Eval? 37 Heaven @ http://thirty-seven.org

off-by-one rsAgeEval:  8! / 6! - sqrt(4) = 55-1
* RoadHacker was 55 years young when he found this road sign.

off-by-one rsAgeEval:  8! / (6 / sqrt(4))! = 55+1
* RoadHacker was 55 years young when he found this road sign.
