Simple One Line Calculator
I've seen other people posting their calculators recently, and I decided to share one I made.
What makes it special
Obviously, It's made with only one line of code, but it's also done pretty well, in my opinion(Because you can just merge lines together with a semicolon, and I didn't do that).
However, it can only do one operation. It's set for addition right now, but that can be easily changed.
