This is one of those mind blowing, fantastic applications that is well worth the money. It is, no joke, a full-on classroom in your iPhone. It covers math from the simplicity of addition all the way to the complications of probabilities and statistics. Basically, a full Junior High and High School curriculum in the palm of your hand, or on your iPad.
The application is broken down into chapters and the chapters have lessons and problems to work on. Each chapter and sub-chapter and every problem contained therein has a video presentation of a math teacher showing you, step by step, how to do the math, explaining every move, every step of the way. It's actually better and easier to use this application than I remember High School being in a classroom.
Each section is followed up by a quiz which has basic math problems, and challenges which actually give examples of real life problems and asks you to use what you just learned to figure out the answer, and goes like that every step of the way. It's full High School math education, made simple and easy, all terms defined and explained and all procedures broken down into easy to duplicate and understand exact steps.
The app is designed to get someone up to the level of passing the math test of the GRE (Graduate Record Examinations) which are standardized tests for getting into graduate school. But this application has so many obvious uses for students of all ages and ability.
If you are home schooling a tween or teen, tutoring, or just need help in mathematics, this is the application for you ALL THE WAY!
Compatible with iPhone, iPod touch, and iPad. Requires iOS 4.3 or later.
