```   +-----------------------+
| WARNING:  Speed Humps |

```
```   the numbers are:  20  1/2  7  9  4  6

the math is:  (sqrt(sqrt(7 + 9)) + sqrt(4) + 6) / (1/2) = 20

more math:  ((4! / 6)! - 20) * (1/2)) + 7 = 9

log(n) math:  log(20 * (1/2)) + log(6 + 4) + 7 = 9

rs42Eval:  20 / (1/2) + sqrt(9 - 7 + 6 - 4) = 42
* 42 is the "Answer to Life, the Universe, and Everything"

rsPiEval:  (20 + 4^(1/2)) / (sqrt(9)! - 6 + 7) = Pi
* 22/7 approximates Pi (3.14) rounded to nearest hundredth

rsPhiEval:  (1/2) + (sqrt(20 / 4) / (9 - 7! / 6!)) = Phi
* Phi is the golden ratio and it approximates 1.61803399

average math:  sqrt(20 / (1/2) + 4 * 6) = avg(7, 9)

more average math:  avg(7, 9) * avg(4, 6) = 20 / (1/2)
