BARS Milestone: This was the 500th BARS (Basic Arithmetic Road Sign). The 500th BARS was posted on 11 October 2008, which was 881 days since MathBabbler started BARS on 15 May 2006.

This no parking sign is in Guadalupe, Arizona.

The no parking sign says...

```   +---------------+
|   NO PARKING  |
|  between the  |
|   hours of    |
| 7:45am-8:45am |
|    Mon-Fri    |
| 1:00pm-1:45pm |
|      Wed      |
| 3:00pm-3:45pm |
|    Mon-Fri    |
+---------------+
```
```   : is a delimiter

the numbers are:  7  45  8  45  1  0  1  45  3  0  3  45

the math is:  (7 * (8 - 1) - 3 * 0! - 0!) * 45 * 45 * 45 = 45^(3 + 1)

more math:  45 - 45 + 45 - 45 + 3 - 3 + 8 - 7 + 1 - 1 + 0 = 0!

more math:  (45/45 + 45/45 + 3/3) * (1 + 1) + 0! + 0! = 8! / 7!

more math:  (8 + 7) / 3 - (45 / (45 / (45 / (45 / 3)))) + 0 + 0 - 1 = 1

rsPiEval:  (8 * 3 - sqrt(7 - 3)) / sqrt(45^0 + 45^0 + 45 + 1^45 + 1) = Pi
* 22/7 approximates Pi (3.14) rounded to nearest hundredth

rsPhiEval:  (0!^0 + sqrt((8+7)/3-(45/(45/(45/(45/3))))+ 3))/(1+1) = Phi
* Phi is the golden ratio and it approximates 1.61803399

rsAgeEval:
sqrt(45 + 45 + sqrt(45 + 45 + 8 + 1^0 + 1^0)) * 3 + 7 * 3 = 51
* TempeHiker was 51 years young when he found this sign

rs42Eval:
sqrt(45 + 45 + sqrt(45 + 45 + 8 + 1^0 + 1)) * (7 - 3) + 3 - 0! = 42
* 42 is the "Answer to Life, the Universe, and Everything"
