There is a staircase with 10 steps. A child runs up the steps, either 1 step or 2 steps with each stride. How many different ways can the stairs be climbed by him?

Either way, hh3 got it wrong with his answer. There was not one way as explained by him, but 2 ways.

Not only did I miss something, I missed a lot - combinations of the 2 step options! The actual ways would be much more.
