EcSubtract - A Subtraction Learning System Game app for iPhone and iPad

Its not true that some students dont do well in math, because they are not smart enough to understand it... The real reason is that they dont take the time to study and practice math. To put it in more common and simple words, students are lazy, thats the real problem. Practice will not make you perfect, because theres nothing perfect in this universe… Practice will help you to improve your math skills, for that reason I created this app, to help any student that has the will to learn and by the use of this app, to get better grades in math. If you are a student, I suggest to invest a little time in you, make some time to practice math. You are the future and technology has a lot to do with math.

This app consists in 4 modules:
1-Beginner
2-Intermediate
3-Advanced
4-Master

To benefit and achieve success by the use of this app, the student MUST do each module in sequence. NO EXCEPTIONS!!!

Each module has a higher grade of difficulty. Each module has 12 tables. Each table is locked and the only way to unlock the next table is by scoring 100 percent in the previous table. This is math! not history.

Each exercise that the student fails will be accumulated in the FOCUS section. The purpose of this section is to accumulate those exercises that the student is having difficulty. The student responsibility is to keep this section empty by doing the exercises in the section FOCUS. Each exercise that the student answers correctly in the section FOCUS, will be removed from that section.

I sincerely wish and hope that this tool will help you in math.
