### BARS::Exit 1 on West-Side Loop 101 in Phoenix, Arizona

 MathBabbler saw numerous road signs on southbound Loop 101 that are potential BARS. He did not get any pictures and he doesn't know when he will get a chance to get the pictures.

These road signs are on southbound Loop 101 on the west-side of Phoenix, Arizona.

```   +-----------+ +-------------+
|  Exit 1A  | |   Exit 1B   |
| I-10 East | |  I-10 West  |
|  Phoenix  | | Los Angeles |
+-----------+ +-------------+
```
```   the numbers are:  1  10  1  10

the math is:  1 * 10 = 10^1

RSeval[a]:  1 * 10 * 10 + 1 = 101

more math:  sqrt(10^(1 + 1)) = 10

more math:  (10 / 10 - 1)! = 1

more math:  10^(1 - 1) = log(10)

more math:  log(10) + log(10) - 1 = 1

[solve for 'n]:  n + n - 1 = 1
```

[a] An RSeval is when an equation is found that evaluates to the highway number on which the road sign was found. The road signs used in this BARS were found on Loop 101.
