This fun site calls attention to all the great math problems that work themselves out in our roadway signs. For instance, here's a sign found on Highway 85-ALT southbound out of Warm Springs, Georgia showing a simple multiplication problem, 3 x 12 = 36. Neat right? Well, consider the genius that figured this one out… LINK WOW. Just… wow.
