### BARS::65 Miles From Kingman on Route 66 in Arizona

This road sign is on westbound Route 66 in Arizona.

```   +--------------------+
| Peach Springs   19 |
| Truxton         28 |
| Kingman         65 |
+--------------------+

This road sign demonstrates the motivation for creating
BARS functions and rsEvals.
```
```   the numbers are:  19  28  65

the math is:  none found

BARSfunc math:  sqrt(28 - 19)! = spf(spf(spf(65)))
* spf(n) = the sum of the prime factors of n
* spf(65) = 5+13 = 18; spf(18) = 2+3+3 = 8; spf(8) = 2+2+2 = 6

BARSfunc math:  28 - spf(65) = sum_digits(19)
* sum_digits(n) = sum the digits of n
* domain:  n must be a prime number

BARSfunc math:  65 % 28 = mult_digits(19)
* mult_digits(n) = product of the digits of n
* domain:  n must be a prime number

BARSfunc rsPiEval:  (19 + spf(28)) * spf(spf(spf(65))) degrees = Pi radians
* spf(28) = 2+2+7 = 11

BARSfunc rsHwyEval:  65 + ceil(19 / 28) = 66
BARSfunc rsHwyEval:  65 + floor(19 / 28)! = 66
* This road sign is on Route 66.
