**GeoGebra** is an excellent multifunctional cross-platform math application that will be a good helper to anyone who is somehow connected in school or work with the need to conduct various mathematical operations. This program combines such sections as geometry and algebra, table construction, statistical and arithmetic operations, and much more. At the same time, all these sections are dynamically interconnected in one package and are fully synchronized. It is possible to use equations, coordinate grid control, build graphs in 2D or 3D modes, etc.

Conveniently, with the help of the program, you can not only carry out the necessary mathematical operations, but also create interactive videos for placement on websites and video hosting sites, which can be necessary when preparing teaching aids.

In this case, everything is decorated in an excellent intuitive interface, which even an ordinary student can master. So with GeoGebra, the study of mathematics and its derivatives is transformed into an easy and interesting process, allowing you to easily understand the principles of basic operations.

Key features of the application:

- Plotting a given function,
- Construction of various 2D and 3D shapes (circle, ellipse, parabola, torus, cone, etc.)
- A huge number of computational actions: addition, multiplication, subtraction, division, transposition, invert, finding the determinant, etc.
- Finding the intersection points of the curves
- Calculating expectation, variance,
- Work with tables and animations and much more.
