Drawing some lines and a few numbers on a sheet of paper *looks* pretty 
easy. However, you try making it so that when you draw the lines, you 
actually get the *right* answer.

This is more difficult than it sounds...

Sure, the result might just be a few numbers on a page, but it took me 
ages to get it to produce the correct answers. (Do you know the 
mathematical properties of similar triangles? I had to look them up...)
