Anti-Core teaches traditional math, not common core math. The app has multiple levels of addition, subtraction, multiplication and division to teach the basics to higher levels of each operation. Each level has an embedded YouTube video that shows how to do the math and use the app to master each level. It shows carrying the one in addition, borrowing in subtraction, multiplication times tables, and long multiplication and division. The upper levels of multiplication and division will also show where arithmetic mistakes were made and allow corrections of these mistakes to help the user master these levels.
