### BARS::Equivalent Road Signs on AZ Hwy-260 West in Arizona

This road sign and this road sign, which are about twenty yards apart, are on westbound AZ Hwy-260 in Arizona.

```   the 1st road sign

+----------------+
| Cottonwood  15 |
| Clarkdale   16 |
| Jerome      22 |
+----------------+

+----------------------+
| Dead Horse St Pk  15 |
| Tuzigoot Natl Mon 16 |
| Jerome St Pk      22 |
+----------------------+
```
```   the numbers are:  15  16  22  15  16  22

the equivalent math is:  15 + 16 + 22 = 15 + 16 + 22

rsAgeEval:  22 + 16 + 15 - sqrt(15 + 16 - 22) = 50
* RoadHacker was 50 years young when he found these signs.

looking for math using only one sign...

off-by-one Pi math:  (22 * sqrt(sqrt(16)) / (15 - 1) = Pi

observe...
sqrt(16) = 4
sqrt(4) = 2
22 * 2 = 44
44 / 14 approximates Pi (3.14)

off-by-one Pi math:  22 / (sqrt((sqrt(16)! - 15))! + 1) = Pi

observe...
sqrt(16) = 4
4! = 24
24 - 15 = 9
sqrt(9) = 3
3! = 6
22 / 7 approximates Pi (3.14)
