```   the numbers are:  15  3  7  1  1

the math is:  3 * (7 - 1 - 1) = 15

more math:  mode(15, log(3 + 7), 1) = 1

rsPiEval:  (15 + 7) / (3! + 1 * 1) ~= Pi
rsPiEval:  (15 + 3! + 1 / 1) / 7 ~= Pi
* 22/7 approximates Pi rounded to nearest hundredth (3.14)
* 3.1415926535897932384626

rsCardinalityEval:  sqrt(15 + 3 + 7 + 1 - 1) = 5
rsCardinalityEval:  15 / (log(3 + 7) + 1 + 1)) = 5
rsCardinalityEval:  sqrt(15 + 3 * 7) - 1 / 1 = 5
* There are five numbers in these signs.

rs37Eval:  15 + 3 * 7 + 1 / 1 = 37
rs37Eval:  15 * 3 - 7 - 1 * 1 = 37
* Why rs37Eval? 37 Heaven @ http://thirty-seven.org

rs42Eval:  15 * 3 - cuberoot(7 + 1) - 1 = 42
rs42Eval:  7! / (15 / 3)! + 1 - 1 = 42
* 42 is the "Answer to Life, the Universe, and Everything"

rsStateEval:  15 * 3 + cuberoot(7 + 1) + 1 = 48
* Arizona was the 48th state admitted to the Union.

off-by-one rsAgeEval:  7^(1 + 1) + 15 - 3! = 59-1
* RoadHacker was 59 years young when he found these signs.
