Finally! I've been working hard to make a proper calculator. It can add, subtract, multiply, and divide any two numbers, and show you the result as long as it's not too long. If it has more than eight digits, it will show an E. Same thing if your number is less than -99999999. And if you divide, and your result has too many decimal digits, it'll will show another E. (Don't be afraid to try big numbers!) Hope you enjoy this, prince1985
