I completed the challenge: 5
I feel good about my code: 4
I would just like to know what I can do to make my code better. One of the the things I know for sure is not using the eval method(read that it's a security risk and is just not a good idea to use it in a user input). I'm open to your overall impression of my code.
note: I started out with a lot of sudo code but most of it got erased by mistake during moving things around.
