### BARS::Road Sign Math in Kelso, CA

This road sign is in Kelso, California.

```   +-------------+
| I-40     18 |
| Amboy    36 |
| I-15     35 |
| Baker    -> |
+-------------+
```
```   the numbers are:  40  18  36  15  35

the math is: (36 / 18) * (35 - 15) = 40

[solve for 'n']  (36 / 18) * (n - 15) = 40
```

This road sign was found in Kelso, CA, in the Mojave National Preserve. It is along Kelso Cima Road near the northeast corner of the intersection with Kelbaker Road. The picture was taken on Sunday, 9 October 2005, while driving home from attending the DARPA Grand Challenge. RoadHacker was driving Kelbaker Road south through the Mojave National Preserve Baker to I-40, via Kelso and the Kelso Dunes.

##### Update::2009.04.17

This BARS was selected to be one of the BARS of the Week for week #13 of the spring 2009 semester.

```   the numbers are:  40  18  36  15  35

rs42Eval:  40 + sqrt(18 + 36 - 15 - 35) = 42
* 42 is the "Answer to Life, the Universe, and Everything"

rs42Eval:  40 + 18 - 15 - 36 + 35 = 42

rs42Eval:  40 + log((35 + 15) * (36 / 18)) = 42
```
##### Update::2010.03.18

RoadHacker encountered this road sign again on day two (March 15th) of his Pi Day 2010 road trip.

```   the numbers are:  40  18  36  15  35

more math:  35 - 15 - 18 = sqrt(40 - 36)

rsPiEval:  (40 + 15 + 35) * (36 / 18) degrees = Pi radians

rsAgeEval:  40 + sqrt(36) * (35 -15 - 18) = 52
* RoadHacker was 52 years young on Pi Day 2010.
