This e-sign sign is on southbound I-17 in Phoenix, Arizona.

The e-sign sign says...

```+-------------------+
| Minutes To        |
| Durango St     10 |
| I-10  7th Av    9 |
+-------------------+
```
```   the numbers are:  10  10  7  9

the math is:  log(10 * 10) + 7 = 9
more math:  log(10) + log(10) + 7 = 9

rsCardinalityEval:  (7 - sqrt(9)) * 10 / 10 = 4
* There are four numbers in this e-sign.

rsHwyEval:  (10 + 7) * (10 - 9) = 17
rsHwyEval:  ((10! / 9!) + 7) * log(10) = 17
* This e-sign is on I-17.

rs37Eval:  summation(7, 10) + sqrt(9) * log(10) = 37
* Why rs37Eval? 37 Heaven @ http://thirty-seven.org
* summation(7, 10) =  7+8+9+10 = 34

rs42Eval:  7 * sqrt(9)! * 10 / 10 = 42
* 42 is the "Answer to Life, the Universe, and Everything"

rsAgeEval:  10 * sqrt(9)! + 7 % log(10) = 60
* MathBabbler was 60 years of age when he found this e-sign.

off-by-one rsAgeEval:  7 * 9 - log(10) - log(10) = 60+1
off-by-one rsAgeEval:  9! / 7! - 10 - log(10) = 60+1
* MathBabbler was 60 years of age when he found this e-sign.

off-by-one rsStateEval:  summation(7, 10) + 10 + sqrt(9) = 48-1
* Arizona was the 48th state admitted to the Union.

off-by-one rs42Eval:  summation(7, 10) + 10 - sqrt(9) = 42-1
* 42 is the "Answer to Life, the Universe, and Everything"
