This app allows you to learn or practise arithmetic while playing a game where you compete against the clock to beat your own high scores. There are 2 game formats. The traditional way - one table at a time and one line at a time and the multi choice way - one line at a time with a choice of 3 possible answers to choose from. You can select any combination of addition, subtraction, multiplication and division. The R3Tutor app will add fun to learning.
