R2_the_V – King of Math Review

This is a great App to get your mind in shape and to keep your mind sharp. I loaded it for a friend who recently had a stroke and decided to try it myself. I am really impressed by the variety of math problems and the amount of mental calculations & mental recall needed to solve the problems. It's a real challenge. Please enjoy, I enjoy it a lot.
