My mission is not just to create math tutorials, but also to inspire students to work hard and believe they can do difficult things. That’s why I created my 100-Problem math marathon videos to show them that dedication comes first.

My 4000+ math tutorials across my Youtube channels have helped millions of students worldwide to understand the subject better and I will continue to create content. If you would like to directly support my mission, consider becoming a paid member on my Patreon.
