### BARS::Duiven Exit in Germany

This road sign is from Germany and it was submitted by SCC student Sabrina during the fall 2009 semester.

The road sign says...

```   +--------------------+
| A12 Westervoort  2 |
|    A28 Duieven     |
|    Centerpoort     |
|        300 m       |
+--------------------+
```
```   the numbers are:  12  2  28  300

rsAgeEval:  (300 % 28) * 2 + 12 = 52
* MathBabbler was 52 years young when he found this equation.

rs42Eval:  summation(12, 28) - 300 + 2 = 42
* 42 is the "Answer to Life, the Universe, and Everything"

off-by-one math:  300 / 12 + 2 = 28 - 1

off-by-one BARSfunc math:  defactorial(sqrt(12 * 28 - 300)) = 2 + 1

observe...
12 * 28 = 336: 336 - 300 = 36; sqrt(36) = 6
defactorial(6) = 3 because 3! = 6

off-by-one BARSfunc math:  spf(300) - spf(12) + 2 = spf(28) + 1

observe...
spf(n) = the sum of the prime factors of n
spf(12) = 7; spf(28) = 11; spf(300) = 17

playground...
300 + 12 * 2 = 324; sqrt(324) = 18
