RE:   Are Calculators Allowed?

Your math so bad? Don't tell me you can't count yourself or you play cards like exeggutor FRLG with max attack has to count with calculator?

My math is not bad. I can do the YGO math in my head. I never used a calculator to do the YGO math. Not even a pencil and a paper.

Then just caunt yourself, no need to use calculator. You can, do you?
