The road sign says...

+---------------------------+ | Jct CA-14 to Mojave 9 | | Boron 38 | | Jct I-15 Barstow 77 | +---------------------------+the numbers are: 14 9 38 15 77 classic off-by-one math: 77 - 38 - 9 = 14 + 15 + 1 more off-by-one math: sqrt(77 + 38 - 15) = 14 - sqrt(9) - 1 rsAgeEval: 77 - 38 + 15! / 14! - sqrt(9) = 51 * RoadHacker was 51 years young when he found this sign. rs42Eval: 77 - 38 + sqrt(9) * (15 - 14) = 42 * 42 is the "Answer to Life, the Universe, and Everything" rs42Eval: 77 - 38 + sqrt((14 - 15 / sqrt(9))) = 42 * 42 is the "Answer to Life, the Universe, and Everything" rsPiEval: sqrt(9) + 14 / (77 + 38 - 15) ~= Pi * Pi is 3.14 rounded to the nearest hundredth off-by-one rsPiEval: (38 - 15 - 1) / sqrt((14 * 9 - 77)) ~= Pi * 22/7 approximates Pi (3.14) rounded to nearest hundredth off-by-one rsHwyEval: 77 - 38 - 9 + 14 + 15 = 59 - 1 * This road sign was found on CA Hwy-58This road sign was originally used because it is off-by-one from being a "classic" BARS, but it ended up providing a bunch of equations thanks to various and sundry road sign evaluations (rsEvals).
