This road sign is along prime numbered AZ Hwy-73 in Arizona.

The road sign says...

+----------------+ | Ft Apache 1 | | Seven Mile 2 | | East Fork 4 | +----------------+the word "seven" converted into the number 7... the numbers are: 1 2 4 7 the math is: 1 + 2 + 4 = 7 if the number 7 is excluded... the numbers are: 1 2 4 the math is: 2 / sqrt(4) = 1This BARS was discovered on the Pi Day 2008 roadtrip.

## Update::2008.10.31

The following math was discovered on 31 October 2008 after this BARS was selected as one of the BARS of the Week for Week #11 of the fall 2008 semester.

the word "seven" converted into the number 7... the numbers are: 1 2 4 7 the math is: 4 * 2 - 1 = 7 rsPhiEval: (1 + sqrt(7 - 2)) / sqrt(4) = Phi * Phi is the golden ratio and it approximates 1.61803399 rsPiEval: (4! - 2) / (1 * 7) ~= Pi * 22/7 approximates Pi (3.14) rounded to nearest hundredth rs42Eval: 4! * 2 - 7 + 1 = 42 * 42 is the "Answer to Life, the Universe, and Everything" rs42Eval: 7 * (4 + 2) * 1 = 42 * 42 is the "Answer to Life, the Universe, and Everything" rsAgeEval: 7^2 + sqrt(4) - 1 = 50 * RoadHacker was 50 years young when he found this sign. rsAgeEval: 7^2 + (sqrt(4) * 1) = 51 * MathBabbler was 51 years young when he inserted this math. if the number 7 is excluded... the math is: 2^1 = sqrt(4)
