+------------------+ | Rice 49 | | CA-Hwy 177 | | Parker 87 | | Kaiser Mine 11 | | <- Lake Tamarisk | +------------------+the numbers are: 49 177 87 11 rsStateEval: 177 % 49 + log(87 % 11) = 31 * California was the 31st state admitted to the Union. rsAgeEval: 49 + 11 - (177 % 87)! = 54 * MathBabbler was 54 years young when he found this equation. * RoadHacker was 44 years young when he found this road sign. off-by-one math: 177 % 87 = 11 - sqrt(49) - 1 ... spf(n) = the sum of the prime factors of n, where n is a composite number ... 49, 87, 177 are composite numbers; 11 is a prime number ... sum prime factors until we have four prime numbers spf(87) = 32; spf(32) = 10; spf(10) = 7 spf(49) = 14; spf(14) = 9; spf(9) = 6; spf(6) = 5 spf(177) = 62; spf(62) = 33; spf(33) = 14; spf(14) hits 5 the numbers become: 5 5 7 11 BARSfunc math: sqrt(sqrt(11 + 5)) = 7 - 5 BARSfunc rsCardinalityEval: log(5 + 5) * 11 - 7 = 4 * There are four numbers in this road sign. BARSfunc rs42Eval: sqrt(5 * 5 + 11) * 7 = 42 * 42 is the "Answer to Life, the Universe, and Everything" BARSfunc rs42Eval: 5! / 5 + 7 + 11 = 42 * 42 is the "Answer to Life, the Universe, and Everything" BARSfunc off-by-one rsAgeEval: 5 * 11 - 7 + 5 = 53+1 * MathBabbler was 54 years young when he found this equation. * MathBabbler was two weeks shy of 55 when he found this equation. BARSfunc off-by-one rsAgeEval: summation(7, 11) + 5 + 5 = 54+1 * MathBabbler was 54 years young when he found this equation. * MathBabbler was two weeks shy of 55 when he found this equation.
