### BARS::Raton I-25 Exits Sign Seen From Amtrak Southwest Chief

This Raton exits sign was on southbound I-25 near Raton, New Mexico.

The Raton exits sign says...

```   +----------------------+
|  Raton Next 4 Exits  |
| Travelers Facilities |
| 21 Modern Stations   |
| 25 Restaurants       |
| 21 Motels            |
| 2 Campgrounds        |
+----------------------+
```
```   the numbers are:  4  21  25  21  2

the math is:  sqrt(25) + 21 / 21 - 2 = 4

more math:  21 / 21 * 2 = log(4 * 25)

rsPhiEval:  (21 / 21 + sqrt(sqrt(25))) / (4 - 2) = Phi
* Phi is the golden ratio and it approximates 1.61803399

rsCardinalityEval:  (21 % 4) * (21 % 2) * sqrt(25) = 5
* There are five numbers in this sign.

rsStateEval:  25 * 2 - 4 + 21 / 21 = 47
* New Mexico was the 47th state admitted to the Union.

rs42Eval:  21 + 21 * (4 - cuberoot(25 + 2)) = 42
* 42 is the "Answer to Life, the Universe, and Everything"

rs37Eval:  21 + 21 - cuberoot(25 + 2) - sqrt(4) = 37
* Why rs37Eval? 37 Heaven @ http://thirty-seven.org

BARSfunc rsPiEval:  (21 + 21 + 2) / (4 + spf(25)) ~= Pi
* 22/7 approximates Pi rounded to nearest hundredth (3.14)
π ~= 3.14159265358979323846264338327950
* spf(n) = the sum of the prime factors of n
domain: n must be a composite number
* 25 is composite; spf(25) = 5+5 = 10

off-by-one rsAgeEval:  21 + 25 + 21 - 4 - 2 = 60+1
* MathBabbler was 60 years young when he found this equation.
