I am to do a simple calculator in C# windows forum. This is my first time doing C# and I've scoured what I could to figure this out. I'm not looking to copy and paste, I want to understand what I'm doing. My biggest issue at this moment is figuring out how to have the calculator solve a line of numbers. My calculator you can hit the buttons to enter numbers and the expression or whatever, but I can only figure out how to do it with two numbers. Any Ideas?
