WORK IN PROGRESS Inspired by my friend @KSanime3dot14, he's in my coding class (see my school account), and we decided to do this as a challenge. >:D Do calculator stuff. MATHEMATICS. Type your expression into the display using the keys, and press "=" to get a result. Use backspace to erase the last thing you typed. I just explained a calculator to you lol Also, you can't use more than one expression at once, or have the number too large. So you can't do something like 5*3+9-2, or 1111111111111111111111111 111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111, or whatever.
