### BARS::Mileage Rock in Quartzsite, Arizona

This mileage rock is in Quartzsite, Arizona.

The mileage sign says...

```   +------------------+
| Flagstaff    256 |
| Lake Havasu   88 |
| Las Vegas    220 |
| Laughlin     133 |
| Los Angeles  250 |
| Phoenix      120 |
| Tucson       237 |
| Yuma          81 |
+------------------+
```
```   the numbers are:  256  88  220  133  250  120  237  81

the math is: no math quickly found

compositeRS: All of the numbers are composite numbers.
* note: this is the first usage of the compositeRS label

...playground #0...

the numbers sorted:  256  250  237  220  133  120  88  81

256 - 250 =  6
237 - 220 = 17
133 - 120 = 13
88 -  81 =  7

the new numbers are:  6  17  13  7

the math is:  (7 - 17 + 13)! = 6

more math:  13 % 6 = log(17 - 7)

rsCardinalityEval:  log(17 - 13 + 6) + 7 = 8
* There are 8 numbers on this mileage rock.

rs37Eval:  7! / 6! + 17 + 13 = 37
rs37Eval:  6 + (17 - 13)! + 7 = 37
* Why rs37Eval? 37 Heaven @ http://thirty-seven.org

rs42Eval:  7! / ((17 + 13) / 6)! = 42
rs42Eval:  sqrt((7 * 6)^(sqrt(17 - 13)) = 42
* 42 is the "Answer to Life, the Universe, and Everything"

rsAgeEval:  (sqrt(17 - 13) + 6) * 7 = 56
* MathBabbler was 56 years young when he found this equation.

off-by-one math:  sqrt(6 + 17 + 13) = 7-1
off-by-one rs42Eval:  6 + 17 + 13 + 7 = 42+1

...playground #1...

the original numbers are:  256  88  220  133  250  120  237  81

256 - 220 = 36
81
250 % 120 = 10
237 - 133 - 88 = 16

the new numbers are:  36  81  10  16

* do some equationeering... (i.e. find equations)

...playground #2...

This mileage rock contains eight composite numbers, so do some
equationeering using the spd function.  Note: The spd function
become a BARSfunc on 23 November 2013.

* spd(n) = the sum of the proper divisors of n
domain: n must be a composite number
