Mathematics is the subject where the gap between good teaching and bad teaching is widest. A bad maths teacher produces students who memorise procedures without understanding why they work. A good one produces students who see structure, build intuition, and can solve problems they have never encountered before. YouTube has made the best maths teachers in the world freely available to anyone with an internet connection.
This guide covers the best mathematics YouTube channels in 2026, organised by level and subject, with honest assessments of what each does well and who it is for.
For Intuition and Wonder: 3Blue1Brown
3Blue1Brown (Grant Sanderson) is unlike any other mathematics channel. His "Essence of Linear Algebra" and "Essence of Calculus" series do not teach you to compute — they teach you to see. The animations make abstract geometric transformations visceral. After watching his linear algebra series, eigenvalues are no longer mysterious — they are the natural behaviour of transformations you can visualise.
The Essence of Linear Algebra playlist is essential viewing for anyone studying machine learning, computer graphics, or university-level mathematics: https://courseifier.com/course/PLZHQObOWTQDPD3MizzM2xVFitgF8hE_ab
3Blue1Brown's channel does not replace a course — it is not meant to. It is the intuition layer that makes a course learnable. Watch his series first, or watch it alongside a more procedure-focused course, and the difference in comprehension is dramatic.
For School and Foundations: Khan Academy
Khan Academy's mathematics curriculum covers arithmetic through multivariable calculus. The instruction style is methodical and patient, and the platform includes interactive exercises that let you practice immediately after watching. For anyone who has gaps in foundational maths — school concepts they never fully understood — Khan Academy is the most comprehensive free option.
The YouTube channel is a companion to the main platform. For structured practice with feedback, the full site (khanacademy.org) is superior to YouTube alone. For video content you can track and annotate, open the YouTube playlists on Courseifier at https://courseifier.com.
For University Calculus: Professor Leonard
Professor Leonard's full-semester Calculus 1, 2, and 3 courses on YouTube are the closest thing to attending a genuinely excellent university calculus class, for free. His lectures are long — two to three hours per session — but they are dense with explanation, worked examples, and the kind of thoroughness that textbooks assume you will fill in yourself.
Calculus 1 is split across three playlists. The first section: https://courseifier.com/course/PLF797E961509B4EB5
The second section: https://courseifier.com/course/PLDesaqWTN6EQ2J4vgsN1HyBeRADEh4Cw-
The third section: https://courseifier.com/course/PLDesaqWTN6ESk16YRmzuJ8f6-rnuy0Ry7
Professor Leonard is the standard recommendation in most online maths communities for anyone struggling with university calculus, and for good reason. His explanation density per lecture is higher than most textbooks.
For JEE and Competitive Maths: Vedantu and PW
For Indian students preparing for JEE or similar competitive exams, the mathematics content from Vedantu's YouTube channel — particularly Nishant Vora's coordinate geometry and calculus sessions — is strong and directly GATE/JEE-aligned. PhysicsWallah's mathematics faculty covers Algebra and Calculus in the same structured, intuition-first style as Alakh Pandey's Physics content. Both are free on YouTube.
Pair these with our post on best YouTube channels for JEE preparation for a full subject-wise study plan.
For Problem-Solving and Competitions: blackpenredpen
blackpenredpen (Steve Chow) solves calculus, integration, and competition problems live, with no editing. Watching him work through a hard integration by parts problem or a differential equation is useful not for the answer but for seeing how an expert thinks — the false starts, the substitution attempts, the pattern recognition. His "100 integrals" videos are a rite of passage in online maths communities.
blackpenredpen is not a structured curriculum. It is a supplement — the equivalent of watching a skilled practitioner work, which research on expertise development consistently shows is valuable.
For Graduate-Level Mathematics: MIT and Cambridge on YouTube
For real analysis, abstract algebra, topology, and other graduate-level subjects, MIT OpenCourseWare and Cambridge's YouTube uploads are the best free resources. These are not polished productions — they are recorded lectures from real courses, sometimes with a camera pointed at a blackboard from across the room. The content is what matters, and it is exceptional.
For anyone building toward mathematics at this level, the combination of 3Blue1Brown (intuition) + Professor Leonard (computation) + MIT OCW (rigour) covers the full spectrum from visual understanding through formal proof.
How to Study Maths From YouTube Effectively
Mathematics is the subject where passive watching fails most completely. You can watch a calculus lecture and feel like you followed every step, then sit down with a problem and be immediately stuck. The issue is that following someone else's reasoning and producing your own reasoning are completely different skills.
The effective approach: pause after every worked example and attempt to solve a similar problem before watching the next one. Cover your notes and rederive each result from scratch. Take notes in a way that captures the why, not just the how. Our post on how to take notes from YouTube lectures covers the method in detail.
Courseifier's Markdown note editor supports KaTeX, so you can write mathematical notation — integrals, summations, fractions — directly in your notes alongside the lecture. For maths study specifically this matters: notes you cannot write formulae in are incomplete. Open any maths playlist on Courseifier to get started: https://courseifier.com
