### BARS::Off-By-One Signs on the Turquoise Trail in New Mexico

RoadHacker drove NM Hwy-14 (the Turquoise Trail) on Pi Day 2007 (i.e. 3/14). He found two road signs, but only off-by-one math has been found in both road signs. Math was found when the road signs were combined.

This road sign was found on southbound NM Hwy-14 on Pi Day 2007 in New Mexico.

```   +------------------+
| San Antonio    1 |
| Cedar Crest    5 |
| Tuieras        7 |
+------------------+

the numbers are:  1  5  7

the off-by-one math is:  7 - 5 = 1 + 1
```

This road sign was found on northbound NM Hwy-14 on Pi Day 2007 in New Mexico.

```   +-----------------+
| Golden       12 |
| Cerrillos    26 |
| Santa Fe     46 |
+-----------------+
| Turquoise Trail |
+-----------------+

the numbers are:  12  23  26  46

the off-by-one Pi math:  23 / (46 - 26 - 12) = (23 - 1)/(8 - 1) = Pi

observe...
22/7 approximates Pi (3.14)
```

Math was found if the two Turquoise Trail roads signs are combined.

```      NM Hwy-14 South        NM Hwy-14 North
+------------------+    +-----------------+
| San Antonio    1 |    | Golden       12 |
| Cedar Crest    5 |    | Madrid       23 |
| Tuieras        7 |    | Cerrillos    26 |
+------------------+    | Santa Fe     46 |
+-----------------+

the numbers are:  1  5  7  12  23  26  46

the math is:  23 + 26 - 46 + 7 + sqrt(5 - 1) = 12
