This road sign is on southbound NM Hwy-52 in New Mexico.

The road sign says...

+----------------+ | NM-163 19 | | Winston 57 | +----------------+the numbers are: 163 19 57 BARS functions reverse_digits(n), sum_digits(n), mult_digits(n) can be used if 'n' is a prime number. BARS function spf(n) can be used if 'n' is a composite number. observe... 163 is prime; reverse_digits(163) = 361; sqrt(361) = 19 sum_digits(163) = 10; mult_digits(163) = 18 19 is prime; reverse_digits(19) = 91; spf(91) = 20 sum_digits(19) = 10; mult_digits(19) = 9 163 % 19 = 11; 163 % 57 = 49; spf(57) = 22 BARS functions were created to help make every road sign a BARS. rsAgeEval and rsHwyEval: 163 % 57 + sqrt(mult_digits(19)) = 52 * RoadHacker was 52 years young when he found this road sign. * This road sign was found on NM Hwy-52. rs42Eval: sqrt(reverse_digits(163)) + spf(57) + log(sum_digits(19)) = 42 * 42 is the "Answer to Life, the Universe, and Everything" rsStateEval: sqrt(reverse_digits(163)) + sqrt(mult_digits(19))! + spf(57) = 47 * New Mexico was the 47th state admitted to the Union. rsPiEval: spf(57) / (sum_digits(163) - sqrt(mult_digits(19))) ~= Pi * 22/7 approximates Pi (3.14) rounded to nearest hundredth observe... The two square numbers nearest to 163 are 144 and 169. 163 - 19 = 144 ... 163 + (57 / 19)! = 169
