```   the numbers are:  2  81  4

the math is:  2 + 4 = sqrt(sqrt(81))!
more math:  avg(2, 4) = sqrt(sqrt(81))

rsCardinalityEval:  4 - 81 % 2 = 3
rsCardinalityEval:  2 + 81 % 4 = 3
rsCardinalityEval:  sqrt(4 * sqrt(81)) / 2 = 3
* There are three numbers is this road sign.

rs42Eval:  2 + floor(81 / 4) = 42
rs42Eval:  floor(81 / 2) + sqrt(4) = 42
* 42 is the "Answer to Life, the Universe, and Everything"

off-by-one math:  2 * 4 = sqrt(81)-1

off-by-one rsStateEval:  ceil(81 / 2) + 4 = 46-1
* Oklahoma was the 46th state admitted to the Union.

off-by-one rs37Eval:  2 + 4 * sqrt(81) = 37+1
* Why rs37Eval? 37 Heaven @ http://thirty-seven.org
