### BARS::Approaching Avenue 3E in Yuma, Arizona

This road sign is on westbound I-8 just east of Yuma, Arizona.

The road sign says...

```   +---------------------------------+
| Avenue 3E   US Hwy-280    2 1/4 |
| 16th St   US Hwy-95           4 |
| Weigh Station             4 3/4 |
+---------------------------------+
```
```   the numbers are:  3   280   (2 1/4)  16   4  (4 3/4)

the math is:  (95 - (280 / 4) + 3) / (2 1/4 + 4 3/4) = sqrt(16)

observe...
280 / 4 = 70
95 - 70 = 25
25 + 3 = 28
2 1/4 + 4 3/4 = 7
28 / 7 = 4
sqrt(16) = 4
```

Paul Dickson once said... "When working toward the solution of a problem, it always helps if you know the answer." Caution should always be exercised when using the word always.

The following is a solve for 'n' exercise.

```   the math was:  (95 - (280 / 4) + 3) / (2 1/4 + 4 3/4) = sqrt(16)

solve for n :  (95 - (280 / 4) + n) / (2 1/4 + 4 3/4) = sqrt(16)
```
