RoadHacker saw a Pi road sign while driving on westbound I-40 in Arizona. He was not able to get a picture.

The road sign says...

+--------------------+ | AZ Highway-77 3 | | Holbrook 7 | | Flagstaff 102 | +--------------------+the numbers are: 77 3 7 102 the number system math is: 77 / 7 = 102_{3}rsPiEval: (102 - 77 - 3) / 7 ~= Pi * 22/7 approximates Pi rounded to nearest hundredth (3.14) * 3.1415926535897932384626 rs42Eval: 3!! / sqrt(102 - 77)! * 7 = 42 * 42 is the "Answer to Life, the Universe, and Everything" rsCardinalityEval: 102 - 77 - 3 * 7 = 4 * There are four numbers in this road sign. off-by-one rsStateEval: sqrt(102 - 77)! / 3 + 7 = 48-1 off-by-one rsStateEval: 102 - 77 + (7 - 3)! = 48+1 * Arizona was the 48th state admitted to the Union. off-by-one rs37Eval: 77 - 102 / 3 - 7 = 37-1 * Whyrs37Eval? 37 Heaven @ http://thirty-seven.org## Updated::2018.05.21

the numbers are: 77 3 7 102 more math: 77 % 3 = sqrt(102 % 7) more math: avg(3, 7) = sqrt(102 - 77) more math: summation(3, 7) + 77 = 102 * summation(3, 7) = 3+4+5+6+7 = 25 77 is composite; spf(77) = 7+11 = 18 102 is composite; spf(102) = 2+3+17 = 22 * spf(n) = the sum of the prime factors of n domain: n must be a composite number BARSfunc math: spf(102) - spf(77) + 3 = 7 BARSfunc rs42Eval: spf(102) + spf(77) + sqrt(7 - 3) = 42 * 42 is the "Answer to Life, the Universe, and Everything" off-by-one BARSfunc rsAgeEval: 77 - spf(102) + 7 - 3 = 60-1 * RoadHacker was 60 years young when he saw this road sign.
