Hey, I am tutoring this kid in java and he has to use TurtleGraphics and BreezySwing, neither of which I have used in a while. I am having trouble figuring out some of his problems. I will post both his code and how I altered his code. I am wondering about a couple of things, one is he uses the method addLabel(), which I cant get to work and am wondering if that is really a method?
Also, he need a main method and I'm not sure what to put in the main method to make it all run.
Here is his code, below this will be how I altered the code:
//"Math is our Game" - A math testing program for First through Fourth grade students

import BreezySwing.*;
import java.awt.*;
import java.util.Random;
