### BARS::Parking Garage Signs in Joliet, Illinois

These parking garage signs are at Presence Saint Joseph Medical Center in Joliet, Illinois.

The parking garage signs signs say...

```+---+ +---------------+ +----------------------+
| 1 | | Speed Limit 5 | | Free Visitor Parking |
+---+ +---------------+ |    Levels 2 thru 4   |
+----------------------+
```
```   the numbers are:  1  2  4  5

the math is:  1 + 5 - 2 = 4

rsAgeEval:  5! / 2 - sqrt(4) * 1 = 58
* GDT was 58 years young when he found these signs.

rsStateEval:  4 * 5 + 2 - 1 = 21
* Illinois was the 21st state admitted to the Union.

rsPhiEval:  (1 + sqrt(5)) / (4 - 2) = Phi
* Phi is the golden ratio and it approximates 1.61803399

rs37Eval:  2^5 + 4 + 1 = 37
* Why rs37Eval? 37 Heaven @ http://thirty-seven.org

rs42Eval:  4! * 2 - 5 - 1 = 42
* 42 is the "Answer to Life, the Universe, and Everything"

rsCardinalityEval:  5 + 2 - 4 + 1 = 4
rsCardinalityEval:  2 * 4 - 5 + 1 = 4
rsCardinalityEval:  ((1 + 2)! * 4) % 5 = 4
* There are four numbers in these signs.

more math:  sqrt(5 + 4) - 2 = 1
more math:  sqrt(2^4) + 1 = 5
more math:  sqrt(4^2) + 1 = 5
more math:  5^2 - 4! = 1
more math:  5 % 2 + 1 = sqrt(4)
more math:  5 - sqrt(4) - 2 = 1
more math:  log(5 * 4 / 2) = 1
more math:  cuberoot(2 * 4) = sqrt(5 - 1)
more math:  5 + 1 = avg(2, 4)!
more math:  avg(1, 5) = avg(2, 4)
more math:  median(1, 2, 5) = sqrt(4)

BARSfunc rsStateEval:  summation(1, 5) + 4 + 2 = 21
* Illinois was the 21st state admitted to the Union.
* summation(1, 5) = 1+2+3+4+5 = 15

off-by-one rs42Eval:  2 * 4 * 5 + 1 = 42-1
* 42 is the "Answer to Life, the Universe, and Everything"

off-by-one rsAgeEval:  4^(1 + 2) - 5 = 58+1
* GDT was 58 years young when he found these signs.
