Quadratic equations are basic to algebra and are the math behind parabolas, projectiles, satellite dishes and the golden ratio.

Microsoft says that the app can be used to help with a wide range of mathematical concepts-from elementary arithmetic and quadratic equations to calculus and statistics.

Solutions to the simplest polynomial equations — called “roots of unity” — have an elegant structure that mathematicians still use to study some of math’s greatest open questions.
