### BARS::Nawiliwili Park on the Island of Kauai in Hawaii

This road sign is on the Hawaiian Island of Kauai.

The road sign says...

```   +-------------------+
| Airport      2 mi |
|              3 km |
| Lihue        2 mi |
|              3 km |
+-------------------+
```
```   the numbers are:  2  3  2  3

the math is:  3! + 2 = 2^3

[solve for 3!]  2^3 = 3! + 2
```
##### Update::2008.11.14

MathBabbler noticed that mileage-to-kilometer ratios are not correct on this road sign.

```   observe...  1 mi = 1.609344 km

[exercise]  fix the road sign

+--------------------------+
| Airport      2 mi        |
|              ________ km |   [round to nearest hundredth]
| Lihue        2 mi        |
|              ________ km |   [round to nearest hundredth]
+--------------------------+
```
##### Update::2008.11.14

There is a squared-numbered 25 mph speed limit sign beyond this road sign.

```   the numbers are:  2  3  2  3  25

the math is:  (2 + 3) * (2 + 3) = 25

more math:  log(sqrt(25 * 2 * 2)) * 3 = 3

more math:  (sqrt(3! * 3!) - sqrt(25)) * 2 = 2

rsPhiEval:  (3 / 3 + sqrt(sqrt(25))) / sqrt(2 + 2) = Phi
* Phi is the golden ratio and it approximates 1.61803399

rsPiEval:  (25 - 3) / (2 + 2 + 3) = Pi
* 22/7 approximates Pi (3.14) rounded to nearest hundredth

rsAgeEval:  25 * 2 - 3 + 3 + 2 / 2 = 51
* RoadHacker found this sign at the age of 51 years young.

rs42Eval:  25 * 2 * (3 - 2) - 2^3 = 42
* 42 is the "Answer to Life, the Universe, and Everything"
