### BARS::One Mile From Ft. Apache on AZ Hwy-73 in Arizona

This road sign is along prime numbered AZ Hwy-73 in Arizona.

```   +----------------+
| Ft Apache    1 |
| Seven Mile   2 |
| East Fork    4 |
+----------------+
```
```   the word "seven" converted into the number 7...

the numbers are:  1  2  4  7

the math is:  1 + 2 + 4 = 7

if the number 7 is excluded...

the numbers are:  1  2  4

the math is:  2 / sqrt(4) = 1
```

This BARS was discovered on the Pi Day 2008 roadtrip.

##### Update::2008.10.31

The following math was discovered on 31 October 2008 after this BARS was selected as one of the BARS of the Week for Week #11 of the fall 2008 semester.

```   the word "seven" converted into the number 7...

the numbers are:  1  2  4  7

the math is:  4 * 2 - 1 = 7

rsPhiEval:  (1 + sqrt(7 - 2)) / sqrt(4) = Phi
* Phi is the golden ratio and it approximates 1.61803399

rsPiEval:  (4! - 2) / (1 * 7) ~= Pi
* 22/7 approximates Pi (3.14) rounded to nearest hundredth

rs42Eval:  4! * 2 - 7 + 1 = 42
* 42 is the "Answer to Life, the Universe, and Everything"

rs42Eval:  7 * (4 + 2) * 1 = 42
* 42 is the "Answer to Life, the Universe, and Everything"

rsAgeEval:  7^2 + sqrt(4) - 1 = 50
* RoadHacker was 50 years young when he found this sign.

rsAgeEval:  7^2 + (sqrt(4) * 1) = 51
* MathBabbler was 51 years young when he inserted this math.

if the number 7 is excluded...

the math is:  2^1 = sqrt(4)
