This road sign is off of US Hwy-95 in California.

The road sign says...

+--------------------------+ | <- Searchlight 36 | | <- Las Vegas 91 | | Needles 17 -> | +--------------------------+the numbers are: 36 91 17 the math is: 91 % 17 = sqrt(36) BARSfunc rsStateEval: reverse(spf(36) + spf(91) - 17) = 31 * California was the 31st state admitted to the Union. * spf(n) = the sum of the prime factors of n * spf(36) = 2+2+3+3 = 10 * spf(91) = 7+13 = 20 * reverse_digits(n) = the digits of n reversed domain: n must be a prime number note: 91 is not prime and the reverse_digits(n) BARS function is defined for prime numbers only; however, 91 is semi-prime (i.e. it has only two prime factors) and an exception is being made for the following equation. BARSfunc math: 17 + reverse_digits(91) = 36
