#### Unizor - Welcome to Advanced Math for Teenagers

This presentation described why you need Unizor and who needs it.

#### Unizor - Introduction

Introducing an educational Web site of advanced mathematics for high school students.

#### Unizor - Advanced Math 4 Teens - Start

Unizor features a curriculum for advanced course of mathematics for high schools. The word "advanced" we mean in terms of depth of learning, rather than in terms of number of topics covered.
Most important characteristic that distinguishes this course from many other on-line math courses is its emphasis on problem solving, rigorousness of presentation and proof of theorems as the main methodology.
Unizor emphasizes "Knowledge" and "Why?" rather than "Skill" and "How?".
Unizor is a mind development tool inasmuch as gym is a tool to develop muscles and stamina.

#### Unizor - Advanced Math 4 Teens - Video Textbook

Video textbook on Advanced Mathematics for high school students.

#### Unizor - Advanced Math 4 Teens - Combinatorics

Combinatorics is extremely important subject of Mathematics.
Studying it and, especially, solving problems presented and analyzed in this course would prove to be extremely important to develop creativity, logic and analytical thinking in students.
This is one of the most useful math subjects in everyday life filled with necessities of making choices.

#### Unizor - Advanced Math 4 Teens - Probability

The subject of Probability is introduced on the elementary level with discussions about its meaning (measure of frequency of past event occurrences or amount of knowledge about event, or measure of prediction about its future occurrence).
Concepts of Conditional probability, random variables, distribution of probabilities and characteristics of these distributions (expected value and variance) are introduced and supplemented with numerous examples and problems.

#### Unizor - Advanced Math 4 Teens - Algebra

This document describes the composition of the Algebra subject of the advanced course of Mathematics for high school students and teachers presented on the Internet at www.unizor.com.
Click "Algebra" on the Unizor main page to get started.

#### Unizor - Advanced Math 4 Teens - Matrices

A relatively superficial introduction to matrices as linear transformations.
Most of the attention is dedicated to 2x2 and 3x3 matrices.
Rules of operation with matrices are discussed as well as their role in solving the systems of linear equations.

#### Math for Teens

I'd like to introduce you to my educational site Unizor, which is created with an idea to redirect studying mathematics from simple memorization of facts, usually forgotten immediately after passing an exam, towards development of intelligence, creativity and analytical thinking, which I consider the real purpose to study mathematics and important throughout the whole life, regardless of profession.
