### BARS::113 Miles From Death Valley in Baker, California

This road sign is on CA Hwy-127 in Baker, California.

The road sign says...

```   +------------+
| CA Hwy-127 |
+------------------+
| Shoshone      56 |
| Death Valley 113 |
+------------------+
```
```   the numbers are:  127  56  113

rsHwyEval:  127 * (113 % 56) = 127
* This road sign is on CA Hwy-127.

BARSfunc math:  113 % 56 = log(sum_digits(127))

BARSfunc rsAgeEval:  56 - mult_digits(113) - log(sum_digits(127)) = 52
* RoadHacker was 52 years young when he found this road sign.

BARSfunc off-by-one math:  127 - 113 = spf(56)+1

...BARS playground...

56 is a composite number (i.e. it's not prime)

* spf(n) = the sum of the prime factors of n
* proper_divisors(n) = set of proper divisors of n
* sum_proper_divisors(n) = sum of proper divisors of n

spf(56) = 2+2+2+7 = 13
proper_divisors(56) = { 1,2,4,7,8,14,28 }
sum_proper_diviors(56) = 64

127 and 113 are prime numbers

* reverse_digits(n) = the digits of n reversed
* sum_digits(n) = sum the digits of n

reverse_digits(113) = 311 and 311 is prime
sum_digits(113) = 5
mult_digits(113) = 3

reverse_digits(127) = 721 and spf(721) = 7+103 = 110
sum_digits(127) = 10
mult_digits(127) = 14
