```   the numbers are:  8  15  11  10  8

* Note: None of the following equations have been
checked for correctness.

the math is:  8 + 8 + 10 - 11 = 15

more math:  8 / (15 - 11) + 8 = 10

more math:  15 - 11! / 10! = sqrt(8 + 8)

more math:  cuberoot(8) + (cuberoot(8) * (15 - 11)) = 10

rsPhiEval:  (11 % cuberoot(8) + sqrt(15 - 10)) / cuberoot(8) = Phi
* Phi is the golden ratio and it approximates 1.61803399

rsPiEval:  (11 * cuberoot(8)) / ((15 - 8) * log(10)) = Pi
* 22/7 approximates Pi (3.14) rounded to nearest hundredth

rs42Eval:  10 * 8 / cuberoot(8) + sqrt(15 - 11) = 42
* 42 is the "Answer to Life, the Universe, and Everything"
