This road sign was on eastbound I-10 in Louisiana.

The road sign says...

+--------------------+ | US 61 3 | | New Orleans 47 | +--------------------+the numbers are: 61 3 47 AllPrimesRS: 61, 3, 47 are all prime numbers * BARS functions such as reverse_digits(n), sum_digits(n), multi_digits(n) can be used when 'n' is a prime number. rs42Eval: (61 - 47) * 3 = 42 * 42 is the "Answer to Life, the Universe, and Everything" off-by-one rsHwyEval: 61 - 47 - 3 = 10 + 1 * This road sign was found along I-10. BARSfunc math: 47 % 3 = sqrt(sqrt(reverse_digits(61))) BARSfunc rsHwyEval: reverse_digits(47) - 61 - 3 = 10 * This road sign was found along I-10. BARSfunc rsAgeEval: reverse_digis(47) - reverse_digits(16) - 3! = 52 * RoadHacker was 52 years young when he found this road sign. BARSfunc rsHwyEval: sum_digits(47) - 3! / multiply_digits(61) = 10 * This road sign was found along I-10. BARSfunc rsHwyEval: sum_digits(47) - 61 % 3 = 10 * This road sign was found along I-10. BARSfunc off-by-one rsAgeEval: cuberoot(61 + 3) + 47 = 52 - 1 * RoadHacker was 52 years young when he found this road sign. BARSfunc math: sqrt(spf(61 - 47)) = 3 * spf(n) = the sum of the prime factors of n * spf(61 - 47) = 14; spf(14) = 2+7 = 9; sqrt(9) = 3 BARSfunc rs42Eval: 47 - sqrt(sqrt(reverse_digits(61))) - 3 = 42 * 42 is the "Answer to Life, the Universe, and Everything" * Louisiana was the 18th state admitted to the Union (1812).
