Solving a system of 2 equations in 2 unknowns app for iPhone and iPad

"Solving a system of 2 equations in 2 unknowns" is the easiest way to learn and practice methods for solving systems of equations.

The first part - I UNDERSTAND ! - shows the three main methods to solve systems: comparison, substitution and elimination. Just set the system, the app solves it for you !

The second part - I TEST MYSELF ! - lets you solve systems by using these methods.

Exercises are randomly generated, so every time you run the app, the systems of equations you have to solve are entirely new !

The app is also linked to Game center, so you can share your results and challenge your friends!
