Abstract
This article shows the effectiveness of teaching mathematics using Hi-tech and through application GeoGebra, which are of particular importance for the future development of e-learning of maths. GeoGebra is an interactive application for geometry, algebra, statistics and calculus, a special software environment that allows you to learn and teach mathematics and natural science from elementary school to university. It can be used for mathematical experiments and innovations both in the classroom and at home for active and problem- oriented learning. In this article, we show a sketch of the using of the above- mentioned software for creating, solving and illustrating mathematical problems, drawing plots and graphs. An algorithm for solving a system of linear equations with two variables using the GeoGebra environment is also described.
