I want the menu to repeat itself 7 times, but the way I have it set up, it only shows the menu repeatedly and does not allow me to input the formulas. I'll let you guys sleep after I figure this one out. Thanks :)
Re: One last question: How to get menu to repeat!
You have a loop. Why don't you use it?

With my current code setup, it repeats the menu 7 times, but does not allow me to input the formula any time after the first. Any help?
Re: One last question: How to get menu to repeat!
The idea is right but you're wrapping the while loop around only the menu() method, which just prints out the method and takes an input that doesn't do anything. I believe you just have to wrap it around the switch statement to loop it.

Thanks Actinistia, I'm finally on my way to understanding this!
