These road signs are on eastbound US Hwy-50 (and prime numbered US Hwy-17) in Virginia.

The road signs say...

+-----------+-----------+ | East | South | +-----------+-----------+ | US Hwy-50 | US Hwy-17 | +-----------+-----------+ | Paris 10 | | Middleburg 21 | | Washington 62 | +---------------+the numbers are: 50 17 10 21 62 the math is: 50 + 10 + sqrt(21 - 17) = 62 [solve for 'n'] 50 + n = 62 - sqrt(21 - 17)These road signs were submitted to RoadSignMath.com on 11 April 2006.

the numbers are: 50 17 10 21 62 rs42Eval: 62 - 50 / 10 * (21 - 17) = 42 * 42 is the "Answer to Life, the Universe, and Everything" rsHwyEval: (62 - 50 + 21 + 17) * log(10) = 50 * This road sign was found on US Hwy-50. rsAgeEval: 62 - 50 + 21 + 17 + log(10) = 51 * MathBabbler was 51 years young when he inserted this equation. [solve for 'n'] 62 - 50 / n * (21 - 17) = 42 [solve for 'log(10)'] (62 - 50 + 21 + 17) * log(10) = 50
