### BARS::Road Signs Along I-10 in California

MathBabbler found a collection of I-10 road signs at Interstate-Guide.com while working on a BAB about the number 10.

Interstate-Guide.com::The numbers are: 10, 1, 14, 9

```   +---------------------------+ +-------------+
| I-10   Santa Monica Fwy & | | 14 ft  9 in |
| Coast Rte            CA-1 | +-------------+
+---------------------------+
```
```   the math is:  10 + 1 + sqrt(9) = 14
```

Interstate-Guide.com::The numbers are: 10, 1, 14, 7, 35

```   +-------------+ +-----------+
|   I-10 Fwy  | |   CA-1    |
| Los Angeles | | Coast Rte |
+-------------+ +-----------+
+-------------+ +-------------------------+
| 14 ft  7 in | | Warning - Curve  35 mph |
+-------------+ +-------------------------+
```
```   the math is:  35 / 7 + 10 - 1 = 14

more math:  sqrt(sqrt(35 - 10) - 1)) * 7 = 14
```

Interstate-Guide.com::The numbers are: 1, 3/4, 4, 5, 1, 3 1/2

```   +-----------------------------------+
| Lincoln Blvd / CA-1 South     3/4 |
| 4th & 5th St                1     |
| Chautauque Blvd             3 1/2 |
+-----------------------------------+
```
```   rsPhiEval:  (1 + sqrt(5)) / ((4 - 3 1/2) / (1 - (3/4))) = Phi

more math:  avg(5, (1 + 1) * (3 1/2)) = ((3/4) * 4)!
```

Interstate-Guide.com::The numbers are: 1, 4, 5, 1/4, 1

```   +--------------------------+ +-----------------------+
| North  Pacific Coast Hwy | | 4th St     CA-1 South |
| CA-1        Oxnard       | | 5th st       Lincoln  |
+--------------------------+ | 1/4 Mile      Blvd    |
+-----------------------+
```
```   the math is:  1 / (1/4) + sqrt(4) - 1 = 5
```

There were more road signs (I-10 is ~2460 miles long), but MathBabbler has saved them for another day.
