### BARS::15 Miles From Cripple Creek, Colorado

This road sign was found on Teller One county road in Colorado.

The road sign says...

```   +-------------------------------+
| Visitor Center       1 mi  -> |
| U.S. Hwy 24          4 mi  -> |
| <- 15 mi Cripple Creek        |
+-------------------------------+
```
```   the numbers are:  1  24  4  15

the math is:  sqrt(24 - 15) + 1 = 4

observe...
24 - 15 = 9
sqrt(9) = 3
3 + 1 = 4

[solve for 'n']  sqrt(24 - 15) + n = 4
```
##### Update::2008.11.28

The following road sign evaluations (rsEvals) were added when this BARS was selected to be one of the BARS of the Week for week 15 of the fall 2008 semester.

```   the numbers are:  1  24  4  15

rs42Eval:  24 + 15 + 4 - 1 = 42
* 42 is the "Answer to Life, the Universe, and Everything"

rs50Eval:  24 + 4! + sqrt(sqrt(15 + 1)) = 50
* RoadHacker was 50 years young when he found this sign.
```
##### Update::2009.02.06

This BARS was updated after it was selected to be one of the BARS of the Week for week 4 of the spring 2009 semester.

Since this BARS last update on 2008.11.28, the `defactorial(n)` function was added to the BARS function library and the modulo arithmetic operator `%` became an official BARS operator.

```   the numbers are:  1  24  4  15

the math is:  defactorial(24) * 4 - 1 = 15

more math:  defactorial(24) - 1 = 15 % 4

more math:  sqrt(24 % 15) + 1 = 4

note:  The defactorial(n) function also has a
corresponding operator n~!, which is a
BARS only arithmetic operator.

[solve for '24~!']  24~! * 4 - 1 = 15

[solve for '24 % 15']  sqrt(24 % 15) + 1 = 4
```
