EQSY app for iPhone and iPad

It is a single application to solve the most common equations for both students and teachers. They are forming the basis of mathematics and physics:

- This application solves systems of linear equations two and three equations with two and three unknowns respectively.

- This application solves quadratic equations step by step, showing the process of calculating the user.

- This application solves cubic equations (and shows factoring when at least one solution is whole).

Also, if the equation of fourth degree is solvable using method of secondary education level, the application will give real solutions.
