### BARS::Classic BARS on US Hwy-180W and US Hwy-191N in Arizona

```   +-------------------+
| Eagar           7 |
| Springerville   8 |
| Show Low       56 |
+-------------------+
```
```   the numbers are:  7  8  56

the math is:  7 * 8 = 56

off-by-one math:  sqrt(56 - 7) = 8 - 1
off-by-one math:  sqrt(56 + 8) = 7 + 1
```

Note: This road sign was first seen during mid-October of 2006; however, the picture wasn't taken until Pi Day 2008.

Prior to finding this classic BARS (Basic Arithmetic Road Sign), we saw this road sign five miles east of Alpine, Arizona, on US Highway-180 West.

```   +---------------------+
| Alpine            5 |
| Eagar            30 |
| Springerville    31 |
+---------------------+
```
```   the numbers are:  5  30  31

the math is:  30 - 5 = 31base-8

This road sign is an off-by-one RSeval because
it is on US Hwy-180.

30 * 5 + 31 = 180 + 1
```

We didn't know if this road sign was north or south of Alpine, but this road sign located five miles east of Alpine helped us figure out which way to turn once we arrived in Alpine because we knew that Eagar and Springerville are north of Alpine.

##### Update::2009.07.26

This BARS was updated for week one of the Fall 2009 semester.

```   the numbers are:  7  8  56

rsStateEval:  56 - 8! / 7! = 48
* This road sign is in Arizona and Arizona
was the 48th state admitted to the Union.

rs42Eval:  56 - 7 * cuberoot(8) = 42
* 42 is the "Answer to Life, the Universe, and Everything"

off-by-one rs42Eval:  56 - 8 - 7 = 42 - 1
* 42 is the "Answer to Life, the Universe, and Everything"

off-by-one rsAgeEval:  7 * 56 / 8 = 50 - 1
* RoadHacker was 50 years young when he found this road sign.

off-by-one rsAgeEval:  56 - 7 + cuberoot(8) = 52 - 1
* MathBabbler was 52 years young when he found this equation.

off-by-one rsAgeEval:  56 - cuberoot(summation(cuberoot(8), 7)) = 52 + 1
* cuberoot(8) = 2; summation(2, 7) = 2+3+4+5+6+7 = 27; cuberoot(27) = 3
```
##### Update::2010.08.17

This BARS was updated for week one of the Fall 2010 semester.

```   the numbers are:  7  8  56

BARSfunc math:  spf(56) - spf(8) = 7
* spf(n) = the sum of the prime factors of n
* spf(56) = 2+2+2+7 = 13; spf(8) = 2+2+2 = 6

rsAgeEval:  56 - cuberoot(summation(cuberoot(8), 7)) = 53
* MathBabbler was 53 years young when he updated this BARS.
```
##### Update::2011.08.16

This BARS was updated for week one of the Fall 2011 semester.

```   the numbers are:  7  8  56

rsAgeEval:  56 - cuberoot(8! / 7!) = 54
* MathBabbler was 54 years young when he found this equation.
