### BARS::Cochiti Road Sign on Pi Day 2007 in New Mexico

This road sign was found along square numbered NM Hwy-16 on Pi Day 2007 in New Mexico.

The road sign says...

```   +--------------------+
| Pena Blance      9 |
| Cochiti Lake    12 |
| Cochita Pueblo  13 |
| Cochita Lake       |
| Golf Course     15 |
+--------------------+
```
```   the numbers are:  9  12  13  15

the math is:  sqrt(12 + 13) * sqrt(9) = 15

observe...
12 + 13 = 25
sqrt(25) = 5
sqrt(9) = 3
5 * 3 = 15

rsHwyEval:  (15 + 12) / 9 + 13 = 16
The road sign was found on NM Hwy-16.

rsAgeEval:  9 + 12 + 13 + 15 = 49
The road sign was found when MathBabbler was 49 years young.

more math:  sqrt(12 / sqrt(9)) + 13 = 15

observe...
sqrt(9) = 3
12 / 3 = 4
sqrt(4) = 2
13 + 2 = 15

more math:  12 / sqrt(9)! + 13 = 15

observe...
sqrt(9) = 3
3! = 6
12 / 6 = 2
2 + 13 = 15

off-by-one math:  12 - 9 + 13 = 15 + 1
off-by-one math:  sqrt(15 + 13 - 12) = sqrt(9) + 1
off-by-one math:  sqrt(12 + 13) + 9 = 15 - 1
