### BARS::I-10 Road Sign Evaluates To 10

This road sign located along I-10 in Arizona is a Golden RSeval because it evaluates to 10.

The sign says...

```   +----------------------------+
| Hwy-287 Florence Blvd    3 |
| I-8 West                 7 |
| Tucson                  69 |
+----------------------------+
```

The numbers in the sign are `287 3 8 7 69`.

```   (8 - 3)! - ((287 / 7) + 69) = 10

[factorial help: (8-3)! = 5! = 5x4x3x2x1 = 120]

...or...

(69 + (287 / 7)) / (8 + 3) = 10
```

The road sign also evaluates to 50. {another sign}

```   the numbers are:  3  7  8  69  287

the math is:  287 - 69 - 3 x 7 x 8 = 50
```
##### Update::2006.04.26

The road sign almost approximates Pi.

```           69              69
------------------- = ------ = 3.13636363
sqrt(8^3 - 287) + 7     22

rounded(3.13636363, 2) = 3.14
truncated(3.13636363, 2) = 3.13

pi = 3.14159265

observe...

8^3 is 8x8x8 = 512
512 - 287 = 225
sqrt(225) = 15
```
