About the application:

30 Second Challenge has been developed to improve numeracy skills in arithmetic and mental mathematics. These original brain training mini games, which create mathematics fun for all ages, increase powers of memory and speed. There are three levels to play at: BEGINNER, INTERMEDIATE and ADVANCED and there are three heroes to give you the challenges. As you take each challenge the timer records your progress. At the end of each one, you enter your reply and the APP tells you if your reply is correct and how long you took to complete it. Remember to concentrate on getting the right answers. Your speed will improve the more you practise.
