Now it's time to discover the power feature of using a method. This usually means sending data to the method, which you just learned to do. Then we have the method return a value. Previously, we used a void type method. I have mentioned before that this is a keyword for nothing, which means that the function isn't returning anything.

Don't worry if this sounds complicated; it isn't. I remember that, years ago, I had some issues getting my head around it. In practice, this is a very simple concept.
