Three Types

The inaugural sign for Road Sign Math! This sign is interesting because it takes three numbers from three different sources. The exit number, the road number and the distance.



The math is very simple. (Remember the Rules, in signs like this we can omit the "W" on the road number 36!)

$$36 - 35 = 1$$

This sign was found off of Highway 280 in Iowa, Northbound past Cedar Rapids at exit (you guessed it) 35!
