### BARS::Guadalupe Exit on Northbound Loop 101 in Tempe, Arizona

These road signs are on Loop 101 just south of Guadalupe Road in Tempe, Arizona.

The road signs say...

```+-------------+ +--------------+ +--------------+
| Exits 55A-B | |     Exit 55C | |      Exit 56 |
|  US Hwy-60  | |  Baseline Rd | | Guadalupe Rd |
|   Phoenix   | | Southern Ave | |   3/4 Mile   |
|    Globe    | | 1 3/4  Miles | +--------------+
| 2 3/4 Miles | +--------------+
+-------------+
```
```   the numbers are:  55  60  (2 3/4)  55  (1 3/4)  56  (3/4)

the math is:  (2 3/4 - 1 3/4 - 3/4) * (60 - 56) = 55 / 55

observe...
left-hand side:
2 3/4 - 1 3/4 = 1
1 - 3/4 = 1/4
60 - 56 = 4
1/4 * 4 = 1
right-hand side:
55 / 55 = 1

more math:  (2 3/4 + 1 3/4) - (60 - 56) = sqrt(55 / 55 - 3/4)

observe...
left-hand side:
2 3/4 + 1 3/4 = 4 1/2
60 - 56 = 4
4 1/2 - 4 = 1/2
right-hand side:
55 / 55 = 1
1 - 3/4 = 1/4
sqrt(1/4) = 1/2

[solve for 'n']  (2 3/4 + 1 3/4) - (n - 56) = sqrt(55 / 55 - 3/4)

[solve for 'x']  (2 3/4 + 1 3/x) - (60 - 56) = sqrt(55 / 55 - 3/4)
