+-----------------+ | Coolidge 8 | | Florence 17 | | Picacho 27 | +-----------------+the numbers are: 8 17 27 the math is: sqrt(17 - 8) = cuberoot(27) rsCardinalityEval: log(27 - 17) + cuberoot(8) = 3 * There are 3 numbers in this road sign. rsCardinalityEval: 27 / (17 - 8) = 3 * There are 3 numbers in this road sign. rsCardinalityEval: cuberoot(27) * 17 % 8 = 3 * There are 3 numbers in this road sign. rs42Eval: 27 + 17 - cuberoot(8) = 42 * 42 is the "Answer to Life, the Universe, and Everything" number system rs42Eval: 17_{8}+ 27 = 42 * 42 is the "Answer to Life, the Universe, and Everything" BARSfunc rs42Eval: 27 + mult_digits(17) + 8 = 42 * mult_digits(n) = product of the digits of n domain: n must be a prime number * mult_digits(17) = 1*7 = 7 BARSfunc rs42Eval: reverse_digits(17) - 27 - cuberoot(8) = 42 * reverse_digits(n) = the digits of n reversed domain: n must be a prime number * reverse_digits(17) = 71 BARSfunc rsAgeEval: cuberoot(27)! * 8 + sum_digits(17) = 56 * RoadHacker was 56 years young when he found this road sign. * sum_digits(n) = sum the digits of n domain: n must be a prime number * sum_digits(17) = 1+7 = 8 off-by-one rs37Eval: 17 + 27 - 8 = 37-1 * Whyrs37Eval? 37 Heaven @ http://thirty-seven.org off-by-one rs42Eval: cuberoot(27) * 8 + 17 = 42-1
