### BARS::6 Miles From Dee, Oregon

This road sign was found in Oregon during the summer of 2006.

```   +----------------------+
| <-- Dee            6 |
|     Lost Lake     21 |
| To Route 35      --> |
| Hood River     17    |
+----------------------+
```

MathBabbler was not able to find any math in this road sign, but he played with it again after the spf(n) function was created (late-Nov. 2007). [spf(n) outputs the sum of the prime factors of 'n']

```   the numbers are:  6  21  35   17

the math is:  spf(21) + spf(35) - spf(6) = 17

observe...
spf(21) = 10    [prime factors for 21:  3  7]
spf(6) = 5      [prime factors for  6:  2  3]
17 = spf(17)    [17 is a prime number]

[evaluate]  spf(35) = _____

[exercise]  prime factors for 35 are __________
```
##### Update::2010.02.04

This BARS was selected to be one of the BARS of the Week for week #4 of the spring 2010 semester.

```   the numbers are:  6  21  35   17

more math:  21 % (35 - 17)! = 6

rsStateEval:  35 - 6 + (21 - 17) = 33
* Oregon was the 33rd state admitted to the Union.

rsStateEval:  35 - 17 % cuberoot(6 + 21) = 33
* Oregon was the 33rd state admitted to the Union.

off-by-one rsAgeEval:  35 + 21 - 17 % 6 = 50+1
* RoadHacker was 50 years young when he found this road sign.

off-by-one rsAgeEval:  35 + 17 - 21 % 6 = 49+1
* RoadHacker was 50 years young when he found this road sign.

off-by-one rsAgeEval:  35 + 21 - 17 % 6 = 52-1
* MathBabbler was 52 years young when he found this equation.

off-by-one rs42Eval:  35 + 6 + sqrt(21 - 17) = 42+1
* 42 is the "Answer to Life, the Universe, and Everything"

off-by-one rs42Eval:  21 + 17 + 35 % 6 = 42+1
* 42 is the "Answer to Life, the Universe, and Everything"
