This road sign is on eastbound US Highway-136 in Illinois.

The road sign says...

+-------------+ | Adair 9 | | Havana 36 | +-------------+the numbers are: 9 36 the math is: sqrt(9)! = sqrt(36) rs42Eval: sqrt(9)! + 36 = 42 * 42 is the "Answer to Life, the Universe, and Everything" rsCardinalityEval: sqrt(36 / 9) = 2 * There are two numbers in this road sign. BARSfunc math: spf(9) = sqrt(36) * spf(n) = the sum of the prime factors of n domain: n must be a composite number * 9 is composite; spf(9) = 3+3 = 6 BARSfunc rsCardinalityEval: sqrt(spf(36) - spf(9)) = 2 BARSfunc rsCardinalityEval: sqrt(9) - log(spf(36)) = 2 * There are two numbers in this road sign. * 9 is composite; spf(9) = 3+3 = 6 * 36 is composite; spf(36) = 2+2+3+3 = 10
