### BARS::Inconsistent Road Signs on AZ Hwy-89 in Arizona

This road sign and this road sign are on northbound AZ Hwy-89 in Arizona.

```   +---------------+
| Ash Fork   17 |
| Williams   34 |
| Flagstaff  66 |
+---------------+

+---------------+
| Ash Fork    7 |
| Williams   23 |
| Flagstaff  56 |
+---------------+
```

MathBabbler has failed to find any math in either of the two road signs individually, but math was discovered when the two road signs were "added" together.

```   the numbers are:  66  34  17  56  23  7

rsHwyEval:  66 - (34 - 17) + 56 - (23 - 7) = 89
* These road signs are on AZ Hwy-89.

rsAgeEval:  (23 + 7) * 34 / 17 + 56 - 66 = 50

more math:  log(66 - 56) + (17 - 7) + 23 = 34
```

Observe... The mileages given to Ash Fork and Flagstaff imply the two road signs are 10 miles apart; however, the Williams mileages indicate the two road signs are 11 miles apart.

##### BARS Sandbox

This section is used to play around with the numbers to see if more math can be discovered using the BARS FunLib (Function Library).

```   str_to_nbr(s) = n
* converts a string into a number

ash fork: 2777744#33366677755  (sum = 117)
williams: 9444555555444267777  (sum = 120)
flagstaff: 33355524777782333333 (sum = 107)

str_to_nbr("ash fork") = 117
str_to_nbr("williams") = 120
str_to_nbr("flagstaff") = 107
```
