Did you run this program? What results did you get? How did they differ 
from what you expected?

What does being "horrible at mat" have to do with this?

What do you know about defining functions?

Did you write this program yourself?

If you are taking a Python class and don't know what to do either the 
class is poorly designed or you are in the wrong class.

Please say more about this.

We are glad to help, but won't write your homework for you.
