### BARS::Salt River Pima-Maricopa Indian Community in Arizona

While driving to school on the northbound Loop 101 on 10 May 2012, MathBabbler exited the Loop 101 at Thomas Road to take a picture of a field located on the Salt River Pima-Maricopa Indian Community in Arizona. MathBabbler's detour resulted in him finding some steet sign math.

The street signs say...

```   +---------------+
| N. 92 ND 9200 |
+---------------+
+-------+
| STOP  |
---------
| 4-way |
+-------+
```
```   the numbers are:  92  9200  4

the math is:  log(9200 / 92) = sqrt(4)

more math: log(9200) - log(92) = sqrt(4)

rsStateEval:  log(9200 / 92) * sqrt(4) = 48
* Arizona was the 48th state admitted to the Union.

spf(9200) = 2^4+5^2+23 = 41; spf(92) = 2^2+23 = 27; spf(4) = 2+2 = 4
* spf(n) = the sum of the prime factors of n
* domain: n must be a positive composite number

BARSfunc rs42Eval:  spf(9200) + 4 - cuberoot(spf(92)) = 42
* 42 is the "Answer to Life, the Universe, and Everything"

reverse_digits(spf(9200)) * cuberoot(spf(92))! / sqrt(4) = 48
* reverse_digits(n) = the digits of n reversed
* domain:  n must be a positive prime number
* Arizona was the 48th state admitted to the Union.

BARSfunc off-by-one rsAgeEval: spf(9200) + cuberoot(spf(92)) * 4 = 54-1
* RoadHacker was 54 years young when he found these street signs.
