Welcome to the only game show where you test your math skills against... NOBODY! Anyway, here is how this game works: If you get it right, you get a point, if you get it wrong, you will lose a point. To move on to the next question, press the space key. In terms of overall score, just see how many points you got and you can figure it out from there. (By the way, calculators can be used if needed)
