### BARS::57 Miles From Winston, New Mexico

This road sign is on southbound NM Hwy-52 in New Mexico.

```   +----------------+
| NM-163      19 |
| Winston     57 |
+----------------+
```
```   the numbers are:  163  19  57

BARS functions reverse_digits(n), sum_digits(n), mult_digits(n)
can be used if 'n' is a prime number.

BARS function spf(n) can be used if 'n' is a composite number.

observe...
163 is prime; reverse_digits(163) = 361; sqrt(361) = 19
sum_digits(163) = 10; mult_digits(163) = 18
19 is prime; reverse_digits(19) = 91; spf(91) = 20
sum_digits(19) = 10; mult_digits(19) = 9
163 % 19 = 11; 163 % 57 = 49; spf(57) = 22

BARS functions were created to help make every road sign a BARS.

rsAgeEval and rsHwyEval:  163 % 57 + sqrt(mult_digits(19)) = 52
* RoadHacker was 52 years young when he found this road sign.
* This road sign was found on NM Hwy-52.

rs42Eval:
sqrt(reverse_digits(163)) + spf(57) + log(sum_digits(19)) = 42
* 42 is the "Answer to Life, the Universe, and Everything"

sqrt(reverse_digits(163)) + sqrt(mult_digits(19))! + spf(57) = 47
* New Mexico was the 47th state admitted to the Union.

rsPiEval:  spf(57) / (sum_digits(163) - sqrt(mult_digits(19))) ~= Pi
* 22/7 approximates Pi (3.14) rounded to nearest hundredth

observe...
The two square numbers nearest to 163 are 144 and 169.
163 - 19 = 144 ... 163 + (57 / 19)! = 169
