MathBabbler saw these road signs on Facebook.

The road signs say...

+---------------------+ +---------------------+ | South VA-28 to I-66 | | North VA-28 to VA-7 | | Centreville | | Dulles Airport | | Exit 1/4 Mile | +---------------------+ +---------------------+ +-------------+ | Exit 20 MPH | +-------------+the numbers are: 28 66 1/4 28 7 20 the math is: (66 * sqrt(1/4) - 28) * 28 / 7 = 20 more math: (20 / (1/4) - 66) * sqrt(28 / 7) = 28 rsAgeEval: 66 - 20 + 28 * (1/4) + sqrt(28 / 7) = 55 * MathBabbler was 55 years young when he saw these signs. rsAgeEval: 66 - ((1/4) * 20) - 7 + 28 / 28 = 55 * MathBabbler was 55 years young when he saw these signs.
