 Hi, I'm Zor. Welcome to Unizor Education. I would like to introduce you in just a few words what actually Unizor is about. Well, first of all, it's a website, Unizor.com, where I have decided to put a lot of educational material for advanced studies of mathematics for high school students. It's significantly more complex and more rigorous than what usually is explained and presented in most of the high schools. So I have decided to put it as an advanced introduction to mathematics for those students who are interested in challenges, in solving complicated problems, who are interested in more rigorous, more logical foundation of mathematics. Basically, my intention is to use this particular website not only as an educational tool, but as a tool to develop students' creativity, analytical thinking, logic, intelligence, if you wish. Arguably, mathematics presents an extremely broad spectrum of different approaches to achieve these goals. Primarily, I'm concentrating on presenting axiomatic foundation for things which we basically deal every day in school mathematics and complement it with a significantly large number of problems. Some of them are complicated, I would say. And again, the purpose is to develop the students' creativity, not to present them with certain number of skills which they have to memorize. Most of these formulas and properties are forgotten immediately after passing exam. My purpose is to teach students how to think logically, how to approach creatively to solving problems. And I hope that these abilities to solve problems in mathematics would be very handy in the real life where the problems are completely different. It's the analytical approach which I'm trying to develop in students. And basically, I'm trying to use this particular tool, Unisor.com, as a tool to develop minds in as much as, let's say, exercises in gym are the tools to develop the muscles. Students can basically access annual lecture. The site is completely free, it has no advertising. However, the site has certain educational functionality. It introduces the process where a student can be registered and he can have a supervisor or parent actually who enrolls this particular student into courses. And after enrollment, the student not only can listen to lectures but also take exams which supervisor or parent can check the results of and basically mark the topic or course as completed. Also, the site is open with proper authorization to completely new subjects, new lectures, new topics. Everything is possible. Software has been written by me personally, so it all can be arranged. So anyway, this is a tool for high school students who would love to have a challenge and can use the mathematics as a tool to develop their minds. Thank you.
