### BARS::Area 7 Reserved Parking Off-By-One in Tempe, Arizona

This parking sign was found in the Maple-Ash neighborhood in Tempe, Arizona.

The parking sign says...

```   +------------------+
| Reserved Parking |
|      Area 7      |
| resident permit  |
|   parking only   |
|   11am To 1am    |
| except  holidays |
+------------------+
```

We'd have a Pi sign if only the reserved parking hours were `11am` to `2am`.

The power of image manipulation...

PixelPainter switched the 1am to 2am.

```   the numbers are:  7  11  2

the math is:  (11 x 2) / 7 = 3.14

observe:
Pi = 3.14159265...
round(Pi, 2) = 3.14       [rounded to the nearest hundredths]
22 / 7 = 3.14285714...
round(22 / 7, 2) = 3.14
Pi - 22 / 7 = -0.00126448927
```
##### Exercises
1. No or Yes. `Pi` is greater than `22 / 7`.

2. No or Yes. `abs(22 / 7) cents` is less than a penny.

3. Calculate how much it would cost to buy `eight gallons` of gas at `Pi dollars (USD) per gallon`.
