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)

Update::2009.02.20

This BARS was selected to be one of the BARS of the Week for week #6 of the spring 2009 semester.

   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
