This week on Road Sign Math continues to be brought to you by Dave Oosterhuis and his wife Phoebe. This sign brings us closer to their final destination as they cross into Iowa's Year 'Round Playground!



This sign is elegant and understated in it's mathematical connection. It also has a unique quality in the ordering. Typically road signs progress in shortest distance on top to longest distance on the bottom. Here, order was thrown to the window and chaos ruled.

$$9 + 13 = 22$$

This sign was found in Iowa on highway 63 southbound as it connects with highway 9, just south of Lime Springs.
