This road sign in on northbound AZ Hwy-87 in Arizona.

The road sign says...

+---------------+ | Jct 188 19 | | Rye 23 | | Payson 34 | +---------------+the numbers are: 188 19 23 34 the base-8 math is: (sqrt(188 - 19))_{8}+ 23 = 34 observe... 188 - 19 = 169 sqrt(169) = 13 13_{8}= 1 * 8 + 3 * 1 = 11MathBabbler has had a difficult time finding math given the numbers in this road sign; therefore, he looked for math using his BARS functions.

str_to_nbr(s) converts string 's' into the digits MathBabbler must press on his cell phone in order to send 's' as a text message; the function outputs the sum of the digits sum_prime_factors(n) outputs the sum of the prime factors for 'n'str_to_nbr("jct") = 52228 (sum = 19) str_to_nbr("rye") = 77799933 (sum = 54) str_to_nbr("payson") = 72999777766666 (sum = 115) 19 - str_to_nbr("jct") = 19 - 19 = 0 str_to_nbr("rye") - 23 = 54 - 23 = 31 str_to_nbr("payson") - 34 = 115 - 34 = 81 sum_prime_factors(188) = 51 the math numbers become: 51 0 31 81 the math is: 81 - 31 + 0! = 51 rsAgeEval: 81 - 31 + 0 = 50 * RoadHacker was 50 years young when he found this sign. observe... the prime factors for 188 are 2 * 2 * 47 0! = 1
