I personally think this is too easy, anyone with an elementary school education can do addition/subtraction with ease, or at least I would hope. Try making one with more multiplication/division, or even a little algebra. I would love to see one like that.

¡¡¡PLEASE NUMPAD!!! don't numerical row
Good way to keep one's brain (among other things) active lol
Numpad doesn't work.
