Here's what I have I think what we have for easy will work. I wrote some code for easy arithmetic with random numbers in a class called Easy. I also got the MemoryGame class to ask for the number of players, then ask for their names, it then welcomes the user and gives the user a description of the game and prompts the user for which level they want to play. 

Nothing is really connected yet, not sure how we are going to do that. 

I'm also not sure what the error in MemoryGame.java on line 42 means.
What I have so far...
