### BARS::109 Miles to Twentynine Palms on CA Hwy-62 in Earp, California

This road sign is on westbound CA Hwy-62 in Earp, California.

```   +----------------+
| Route 95       |
| Vidal Jct   16 |
| 29 Palms   109 |
+----------------+
```

CA Hwy-62 is RoadHacker's favorite highway so it was disappointing to only find off-by-one math in this road sign. We re-examined the road sign after the spf(n) function was created. The spf(n) function outputs the sum of the prime factors of the input number.

```   the numbers are:  95  16  29  109

off-by-one math:  109 - 95 + 16 = 29 (+ 1)

the math is:  spf(95) + sqrt(16) = spf(109 + 29)

observe...
prime factors of 95 are 5 and 19
spf(95) = 5 + 19 = 24
sqrt(16) = 4
24 + 4 = 28
29 and 109 are prime numbers
29 + 109 = 138
prime factors of 138 are 2 and 3 and 23
spf(138) = 2 + 3 + 23 = 28

rs42Eval:  29 + 16 - sqrt((109 - 95)5) = 42
* 42 is the "Answer to Life, the Universe, and Everything"

observe...
109 - 95 = 14
145 = 9
sqrt(9) = 3
