### BARS::6 Miles From I-55 on IL Hwy-59 in Illinois

MathBabbler visited his mom, dad, and sister during winter break 2015. He drove from his sister's house in Plainfield to his parent's old folks home in Shorewood via Illinois Hwy-59 numerous times. Each time he noticed a road sign that he never got a chance to get a picture of.

```   +-------------------+
| Shorewood       5 |
| I-55            6 |
+-------------------+
```
```   the numbers are:  5  55  6

the math is:  6! % 55 = 5
* 6! = 720; 720 % 55 = 13 R 5

rsPivot5math: 55 / 5 = 5 + 6
* Note: First time usage of rsPivotNmath.

rs42Eval: sqrt(55 - 6)! / 5! = 42
* 42 is the "Answer to Life, the Universe, and Everything"

spf(n) = the sum of the prime factors of n
* domain: n must be a composite number
* 55 is composite; spf(55) = 5+11 = 16

BARSfunc rsCardinalityEval:  sqrt(spf(55)) + 5 - 6 = 3
BARSfunc rsCardinalityEval:  cuberoot(5 + 6 + spf(55)) = 3
* There are three numbers in this road sign.

BARSfunc off-by-one rs37Eval:  (6! / 5!)^sqrt(sqrt(spf(55))) = 37-1
BARSfunc off-by-one rs37Eval:  sqrt(sqrt(spf(55)))^5 + 6 = 37+1
* Why rs37Eval? 37 Heaven @ http://thirty-seven.org

BARSfunc off-by-one rsStateEval:  spf(55) + 6! / 5! = 21+1
* Illinois was the 21st state admitted to the Union.

BARSfunc off-by-one rs42Eval:  6^sqrt(sqrt(spf(55))) + 5 = 42-1
* 42 is the "Answer to Life, the Universe, and Everything"
