This road sign was found on eastbound I-40 on Pi Day 2007 in Albuquerque, New Mexico.

The road sign says...

+-----------------------+ | 8th-6th St 1 1/2 | | 4th-2nd St 1 3/4 | | University Blvd | +-----------------------+the numbers are: 2 4 6 8 (1 1/2) (1 3/4) the math is: (1 3/4 - 1 1/2) * 4 * (6 + 2) = 8 observe... 1 3/4 - 1 1/2 = 1/4 1/4 * 4 = 1 1 * (6 + 2) = 1 * 8 = 8 [solve for 'n'] (1 3/4 - 1 1/2) * 4 * (n + 2) = 8## Update::2009.10.09

This BARS was selected to be one of the BARS of the Week for week #8 of the fall 2009 semester.

the numbers are: 2 4 6 8 (1 1/2) (1 3/4) combine the two mixed numbers: 1 3/4 - 1 1/2 = 1/4 the numbers are: 2 4 6 8 1/4 rsAgeEval: 8 * 6 + 4 * sqrt(1/4) + 2 = 52 * MathBabbler was 52 years young when he found this equation. rsAgeEval: 8 * 6 + 2 - 1/4 * 4 = 49 * RoadHacker was 49 years young when he found this road sign. rsStateEval: 8 * 6 - 2 / sqrt(1/4) / 4 = 47 * New Mexico was the 47th state admitted to the Union. rs42Eval: 8 * 6 - sqrt(4 / (1/4)) - 2 = 42 * 42 is the "Answer to Life, the Universe, and Everything" rsHwyEval: 8 * 6 - 4 - 2 / sqrt(1/4) = 40 * This road sign is on I-40. rsPhiEval: sqrt(1/4) + (sqrt((cuberoot(8) + 6 / sqrt(4))) / 2) = Phi * Phi is the golden ratio and it approximates 1.61803399 rsPiEval: (4! - cuberoot(8)) / (6 + 2 * sqrt(1/4)) = Pi * 22/7 approximates Pi (3.14) rounded to nearest hundredth rsPiEval: (4! - sqrt(2 / sqrt(1/4))) / avg(6, 8) = Pi * 22/7 approximates Pi (3.14) rounded to nearest hundredth rsPiEval: (8 + 2) * (4! - (6 * sqrt(1/4))!) degrees = Pi radians * 180 degrees equals Pi radians Note: These are special rsPiEvals because this road sign was found in Pi Day 2007.
