Franklin the fly starts at the point (0,0) in the coordinate plane. At each point, Franklin takes a step to the right, left, up, or down. After 10 steps, how many different points could Franklin end up at?

There are four possible directions at each step, so the number of possible endpoints is 4*2*10 = 80.
