I am Julian and use my Youtube channel "The Bright Side of Mathematics" to explain students and pupils Maths problems. I make English and German videos to different topics. Also, I am always open for suggestions for a new video series.
With your support, I am able to create new videos to different topics such that everyone can learn Maths! :)
