excellent for keeping you on your toes! – Mental Math - Arithmetic Quiz Review

this is an excellent app for practicing mental calculations. my only complaint, and the reason i didn't give this app a five star rating, is that it should include tutorials on how the calculations are made. it took me a few tries with some of these to figure out what i was supposed to do. other than that, great app!
