When I try to create a dictionary the way explained by you guys, I get a few errors. One error is with Console.WriteLine, I get an error under WriteLine that says "System.Console.WriteLine(string, params object[]) is a 'method' but is used like a 'type'". Another problem I am having is calling my sum. I get an error and the options to either create a new type or a new method. I am sure that it this is due to mistakes that I am making by not fully understanding how to code, but I am having trouble figuring out how I am suppose to properly do this.
