Math Challenge is an educational and reference app available on Android that offers a fun and interactive way to learn math. The app contains a library of game-like math challenges and tricks, which are illustrated simply and with beautiful colors to make learning math an awesome experience. The app includes step-by-step tutorials that teach you useful math tricks and tips, and test your skills with unlimited questions for as much workout as you’d like. The challenge section is divided into three difficulty levels: easy, medium, and advanced, each covering a number of tricks you learned in the tutorial section. This app is most useful for kids, students, and professionals who do a lot of math on a daily basis, as it helps to save valuable time during tests that do not allow calculator use, such as GMAT, GRE, and other tests including GCSE, ACT, and SAT.
