While driving home from California on I-8, RoadHacker saw two road signs that were BARS, but he couldn't get a picture of them. He hopes to get a picture of them someday.

The first road sign said the following...

+---------------------+ | Winterhaven 31 | | Yuma 33 | +---------------------+the numbers are: 31 33 rsHwyEval: sqrt(31 + 33) = 8 * This road sign is on eastbound I-8. rsHwyEval: 33 - 31 = cuberoot(8) * This road sign is on eastbound I-8. rs42Eval: (31_{8}+ 33_{8})_{8}= 42 * 42 is the "Answer to Life, the Universe, and Everything" * Base-8 was used because this road sign was found on I-8.The second road sign said the following...

+---------------------+ | Winterhaven 26 | | Yuma 28 | +---------------------+the numbers are: 26 28 rsHwyEval: 28 - 26 = cuberoot(8) * This road sign is on eastbound I-8. rsAgeEval: 26 + 28 = 54 * RoadHacker was 54 years young when he saw this road sign. BARSfunc rsStateEval: reverse_digits(28 - spf(26)) = 31 * California was the 31st state admitted to the Union. * spf(n) = the sum of the prime factors of n domain: n must be a composite number * spf(26) = 2+13 = 15 * reverse_digits(n) = the digits of n reversed domain: n must be a prime number * reverse_digits(28 - 15) = reverse_digits(13) = 31
