Little White Sign II

David Slauenwhite makes a return with another mathematically significant road sign from Pennsylvania (see Little White Sign). These signs have the potential to bring very intersting math to the game.



The math here is a little deceptive. It's clear to even the casual observer that 2005 - 2002 results in 3, but how to get 3 out of the rest of the numbers!

$${2005 - 2002} = { {50-20} \over {10} }$$

This sign is found on the south-side of Liberty, Pennsylvania, on the old US 15 that was renamed to SR 2005 in the 1990's.
