```   the numbers are:  2  3  3  10  17  24  51

the math is:  24 + 17 + 10 + 2 * (3 - 3) = 51
more math:  2^3 * cuberoot(51 - 24) + 3 - 10 = 17
more math:  mode(3, 2, 10, 17, 3) = cuberoot(51 - 24)
more math:  51 - 24 - 17 - 2 - 3! + log(10) = 3

rsAgeEval:  51 - 24 + 17 + 3 * (3 + 2) * log(10) = 59
* MathBabbler was 59 years young when he found these signs.

rs37Eval:  51 / 17 + 10 + 24 * (2 - 3 / 3) = 37
* Why rs37Eval? 37 Heaven @ http://thirty-seven.org

rs42Eval:  51 - 17 * 3 + 10 + 24 + 2^3 = 42
* 42 is the "Answer to Life, the Universe, and Everything"

rsPiEval:  (51 - 17 + 3! + 3! - 2) / (24 - 10) ~= Pi
* 22/7 approximates Pi rounded to nearest hundredth (3.14)
* 3.1415926535897932384626

rsPhiEval:  (3 / 3 + sqrt(10 / cuberoot(24 / (51 / 17)))) / 2 = Phi
* Phi is the golden ratio and it approximates 1.61803399

rsStateEval:  (51 - 3) * (2 - ((10 + 17 - 24) / 3)) = 48
