### BARS::AZ Hwy-80 Underpass in Bisbee, Arizona

These highways signs were found in Bisbee, Arizona.

The highway signs say...

```   +------------+ +--------------+ +------------+
| AZ 80 West | | 16 FT - 6 IN | | AZ 80 East |
| Old Bisbee | +--------------+ |   Douglas  |
+------------+                  +------------+
```
```   the numbers are:  80  16  6  80

that math is:  log(16 - 6) * 80 = 80

observe...
16 - 6 = 10
log(10) = 1
80 * 1 = 80
```
##### Updated::2011.03.19

This BARS was selected to be one of the BARSOTW (BARS Of The Week) for week nine of the spring 2011 semester.

MathBabbler spent Pi Day 2011 in Bisbee, Arizona.

```   rs42Eval:  80 / sqrt(sqrt(16)) + 80 % 6 = 42
* 42 is the "Answer to Life, the Universe, and Everything"

rsAgeEval:  80 - sqrt(16)! - sqrt(6! / 80) = 53
* MathBabbler was 53 years young when he found this equation.

...math playground...

80 / 16 = 5 ... 5! = 120
80 - 16 = 64 ... sqrt(64) = 8 ... cuberoot(8) = 2
6! = 720
6! / 16 = 45
6! / 80 = 9 ... sqrt(9) = 3 ... 3! = 6
80 / sqrt(16) = 20
80 - sqrt(16)! = 56
22/7 = 44/14 = 66/21 = 88/28 = 110/35 = 132/42 = 154/49 = 176/56
(1 + sqrt(5)) / 2 = Phi (golden ratio ~= 1.61803399)
```
##### Update::2011.03.20

During his Pi Day 2011 visit to Bisbee, MathBabbler returned to the spot of this BARS and took a picture that included two speed limit signs that resulted in MathBABs.us::BARS::AZ Hwy-80 Underpass With Speed Limit Signs in Bisbee, Arizona
