```   the numbers are:  1  31  9  4  1  31  9  6

the numbers sorted:  1  1  4  6  9  9  31  31

the math is: 1 - 1 + 4 + 9 / 9 + 31 / 31 = 6

rsPhiEval:  (31/31 + sqrt((4+6) / (1+1))) / (sqrt(9)! / sqrt(9)) = Phi
* Phi is the golden ratio and it approximates 1.61803399

rsPiEval: (1 + 4 + 9 + 9 - 31 / 31) / (1 + 6) = Pi
* 22/7 approximates Pi rounded to nearest hundredth (3.14)
* 3.1415926535897932384626

rsCardinalityEval:  ((31 - 1) - (31 - 9)) * (9 - 6) / (4 - 1) = 8
* There are eight numbers in this "no dogs" sign.

rsStateEval: 31 * (31 - 9 - 9 - 6 - 4 - 1 - 1) = 31
* California was the 31st state admitted to the Union.

rs37Eval: (31 + 31) / (1 + 1) + ((9 + 9) / 6 * sqrt(4)) = 37
* Why rs37Eval? 37 Heaven @ http://thirty-seven.org

rs42Eval: 31 + 31 - 9 - 9 - (6 + 1 + 1) / 4 = 42
* 42 is the "Answer to Life, the Universe, and Everything"

rsAgeEval:  31 + 31 - ((9 - 1) / 4 * (6 / sqrt(9) + 1)) = 56
* RoadHacker was 56 years young when he found this sign.

rsMaxTweetLenEval:  31 + 31 + 9 * 9 - log(6 + 4) - 1 - 1 = 140
* 140 is the maximum length of a Twitter posting (tweet).
```
##### Update::02018.01.11

MathBabbler saw "No Dogs" again at the start of 2018 when the rsAgeEval was 60.

```
the numbers are:  1  31  9  4  1  31  9  6

rsAgeEval:  31 + 31 - 6 + 4 * (1 - 1)! = 60
rsAgeEval:  319 + 319 + (1 + 1) * (6 - 4) = 60
rsAgeEval:  31 - 9 + 31 - 9 + 4! - 6 - 1 - 1 = 60
* MathBabbler was 60 years young when he found this equation.

rsMaxTweetLenEval:  31 * 4 + 31 * 6 - (9 + 1) * sqrt(9^1) = 280
* After this BARS was created, Twitter increased the
maximum tweet length from 140 to 280.
