This road sign was found in East Troy, Wisconsin.

The road sign says...

+-----------+ | West | | WI Hwy-20 | +-----------+ +--------------------+ | Hwys 12 - 67 8 | | Whitewater 17 | +--------------------+the numbers are: 20 12 67 8 17 the math is: 12 + sqrt(67 - sqrt(17 - 8)) = 20 observe... 17 - 8 = 9 sqrt(9) = 3 67 - 3 = 64 sqrt(64) = 8 12 + 8 = 20 rs42Eval: (67 - 17) - sqrt((20 - 12) * 8) = 42 * the "Answer to Life, the Universe, and Everything" rsAgeEval: (67 - 17) - (20 - 12) / 8 = 49 * RoadHacker was 49 years young when he found this sign. [solve for 'n'] n + sqrt(67 - sqrt(17 - 8)) = 20## Update::2009.05.01

The following math was discovered on 1 May 2009 after this BARS was selected as one of the BARS of the Week for Week #15 of the spring 2009 semester.

the numbers are: 20 12 67 8 17 rsAgeEval: 67 - 17 + 20 / (12 + 8) = 51 * MathBabbler was 51 years young when he found this equation more math: sqrt(sqrt(67 + cuberoot(8) + 12)) + 17 = 20 rsHwyEval: sqrt((sqrt(sqrt(67 + cuberoot(8) + 12)) + 17) * 20) = 20 * This road sign was found on WI Hwy-20 rsStateEval: 67 - 12 - sqrt(8 + 17) - 20 = 30 * This road sign was found in Wisconsin (state #30) This BARS was the first BARS to use a rsStateEval. The rsStateEval was added to the BARS system on 3 May 2009 and this equation was inserted into this BARS on 4 May 2009.
