## What is Khan Academy Matematik?

### A brief introduction to Khan Academy and its mission

Khan Academy is a nonprofit organization that aims to provide a free, world-class education for anyone, anywhere. It was founded in 2008 by Salman Khan, a former hedge fund analyst who started making math videos for his cousins and then uploaded them on YouTube. Since then, Khan Academy has grown into a global platform that offers thousands of videos, exercises, quizzes, articles, and interactive lessons on various subjects, such as math, science, history, art, and more.
