【實用解謎app】Simple Math Workout|最夯免費app-綠色工廠好玩App

Give your brain a little workout in your spare time. Exercise by selecting the greater value of randomly generated addition, subtraction, multiplication, and division problems. As you get them correct, the selection of number sizes increases, and the problems a little more difficult. Get them incorrect, and the selection reduces (and the level marker turns red), and the problems get a little easier.
