A calculator is a device that you use to do math.
How to useEdit
Press the buttons to get an equation. Solve it. Done. So easy. Except learn all about your calculator and get in sync with it.
NB: Not really. A calculator is a magical device that means Maths doesn't need to be done by you! It does it for you. Also, if you type 69 and 42 in, it teleports you to magic numberland, and you get fifteen million dollars. Honest. NAWT REALLY.
