If you wanted to improve your knowledge of a foreign language you learned at school, or if you wanted to learn the basics of an exotic language, you probably reached for the very popular Duolingo application. This service offers excellent tools for learning foreign languages at many levels, and it can be useful even in the basic, i.e. free, version.
In order to expand its horizons, as well as yours, the Duolingo company has announced the introduction of new subjects in its digital classrooms, and the first to join them is mathematics. So soon, with the help of this application, you will be able to learn the basics of mathematics from elementary school, which you probably forgot. For example, how to retroactively remove VAT from the price.
Those who will particularly like this possibility could be elementary school students, because in this way they will definitely be able to master the material that their teachers do not explain well enough. Of course, this is not advice not to go to school, but to determine the material in a simple way.
In addition to the above, there will also be various brain teasers, puzzles for fun and training of mental abilities.
