I am Julian and use my Youtube channel "The Bright Side of Mathematics (Si apre in una nuova finestra)" to explain a lot of different Maths problems to students. I primarily create whole video courses that cover a huge topic but are presented in short video clips. These can be found on YouTube and with your Steady membership you get additional content. Most videos are in English but I also have some translated videos in German as well.
With your support, I am able to create new videos to different topics such that everyone can learn Maths! :)
Go to https://thebrightsideofmathematics.com/ (Si apre in una nuova finestra) to find an overview of all videos.
