### BARS::National Solar Observatory at Sacramento Peak in New Mexico

This entrance sign is to the National Solar Observatory located atop New Mexico's Sacramento Peak.

The entrance sign says...

```   +--------------------------------+
|         Welcome to the         |
|    National SolarObservatory   |
|       at Sacramento Peak       |
| Visiting Hours: Daily, 8am-6pm |
|            CAUTION             |
|      Altitude: 9,250 feet      |
|                2,819 meters    |
+--------------------------------+
```
```   the numbers are:  8  6  9250  2819

the math is:  8 - 6 = ceil(9250 / 2819)
* 9250 / 2819 = 1.81143739

more math:  floor(8 / 6) = floor(9250 / 2819)
ceil(8 / 6) = ceil(9250 / 2819)
* 8 / 6 = 1.33333333

keeping the units attached to the numbers 9250 and 2819:
let... 9250 ft / 2819 m = 1

the numbers are:  8  6  1

rsStateEval:  8 * 6 - 1 = 47
* New Mexico was the 47th state admitted to the Union

BARSfunc math:  sqrt(summation(1, 8)) = 6
* summation(1, 8) = 1+2+3+4+5+6+7+8 = 36

BARSfunc math:  defactorial(6) - 1 = cuberoot(8)
* defactorial(6) = 3 because 3! = 6

spf(9250) = 2+5+5+5+37 = 54 ... 2819 is prime
* spf(n) = the sum of the prime factors of n
