Roots is an educational app developed by Francesco Grassi that focuses on teaching and practicing techniques involving square roots and roots of a higher order. It is an ideal tool for students preparing for algebra or mathematics exams, as well as for teachers who need to prepare homework or examinations for their students.

The app offers six different exercise types, each designed to help users master a specific skill. In Level 1, users learn the basics of simplifying roots, including square root extraction and calculation rules. Level 2 focuses on rationalizing roots, which involves eliminating the root from the denominator. Level 3 introduces expressions with roots, while Level 4 covers the basics of solving equations with roots, starting with simple equations that require only a few steps to be resolved.

For more advanced users, Levels 5 and 6 present equations that become progressively more complicated and require more steps to be resolved. Level 6 specifically focuses on equations that need to be squared twice, often leading to quadratic equations.

With Roots, users can generate equations and exercises that are always different, providing complete solutions. The app is available for iPhone and is free to download, making it easily accessible for anyone seeking to improve their root-solving skills.
