### BARS::Sleeper Car Sign On an Amtrak Southwest Chief

This sleeper car sign was on an Amtrak Southwest Chief.

The sleeper car sign says...

```   +----------------+
| <- Stairs      |
| Up Rooms   A-E |
|    Rooms  1-10 |
|    Rooms 11-15 |
| -> Restrooms   |
+----------------+
```
```   the numbers are:   1  10  11  15

--- equations found while on the train ---

the math is:  1 + log(10) = sqrt(15 - 11)

more math:  sqrt((15 - 10)! + 1) = 11

rsCardinalityEval:  1 * (15 - 1011) = 4
* There are four numbers in this sleep car sign.

rs37Eval:  1 + 10 + 11 + 15 = 37
* Why rs37Eval? 37 Heaven @ http://thirty-seven.org

off-by-one rs42Eval:  (15 - 11) * 10 + 1 = 42-1
off-by-one rs42Eval:  sqrt(1511) * 10 + 1 = 42-1
off-by-one rs42Eval:  sqrt(1115) * 10 + 1 = 42-1
* 42 is the "Answer to Life, the Universe, and Everything"

--- equations found after getting off the train ---

off-by-one rsAgeEval:  summation(1, 11) - 10 + 1 = 58-1
* MathBabbler was 58 years young when he found this sleeper car sign.
* summation(1, 11) = 1+2+3+4+5+6+7+8+9+10+11 = 66
* 66 - 10 + 1 = 58-1
```

This sign was on a train that passed through the states of Arizona (48), New Mexico (47), Colorado (38), Kansas (34), Missouri (24), and Illinois (21). The BARS is going to be updated to include rsStateEvals.
