# Grant Sanderson (3Blue1Brown): Best Way to Learn Math | AI Podcast Clips

TLDRGrant Sanderson, known for his educational channel 3Blue1Brown, shares his insights on the best approach to learning mathematics. He emphasizes the importance of actively engaging with problems rather than passively consuming lectures or reading materials. Sanderson suggests looking at textbook problems before reading the chapters to identify which areas will be challenging. He also recommends using resources like Khan Academy for beginners and leveraging programming to understand mathematical concepts from a practical perspective. Sanderson highlights the effectiveness of teaching others as a method to solidify one's own understanding, referencing a common belief that one retains 90% of what they teach. His advice is aimed at fostering a deep and practical grasp of math, rather than just theoretical knowledge.

### Takeaways

- π The best way to learn math is by focusing on solving specific problems rather than just watching lectures or reading.
- π Seek out resources with well-curated lists of problems, such as textbooks with exercises at the end of each chapter.
- π Before reading a chapter, quickly glance at the questions at the end to identify which ones make sense and which ones don't.
- π€ Engage with the material by reading a bit, then revisiting the questions to see if new insights emerge.
- ποΈββοΈ Persist with the chapter until you've worked through a few exercises, reinforcing the learning process.
- π₯ Grant Sanderson admits that his videos are a part of the learning ecosystem but not a complete learning experience on their own.
- πΆ For beginners, Khan Academy is recommended for its comprehensive set of questions and basic introduction to subjects like linear algebra and calculus.
- π» Learning to program can be a motivating way to explore math, especially for those who may not have been initially interested in the subject.
- π€ Sanderson suggests that creating videos or actively explaining concepts, as he does, can significantly enhance learning.
- π The principle that we remember more of what we actively engage with and teach to others is highlighted as a powerful learning strategy.
- π The anecdote about remembering percentages of what we read, listen to, interact with, and teach is brought up to emphasize the importance of active learning.

### Q & A

### What does Grant Sanderson suggest as the best way to learn math for beginners?

-Grant Sanderson suggests that beginners should focus on solving specific problems and seek out resources with well-curated lists of problems, such as textbooks with exercises at the end of chapters.

### Why does Sanderson recommend looking at the problems at the end of a chapter before reading it?

-He recommends this approach because it allows learners to identify which problems make sense to them, and those that don't, which are the best ones to think about and engage with as they read through the chapter.

### What is Sanderson's opinion on the role of video content in the learning process?

-Sanderson views video content, including his own, as a part of the learning ecosystem but not the complete learning process. He believes that actively working through exercises is crucial for true understanding.

### How does Sanderson feel about Khan Academy for someone just starting out in math?

-Sanderson believes that Khan Academy does a good job for beginners, offering a large set of questions to work through and get comfortable with basic linear algebra and calculus.

### What role does programming play in learning math according to Sanderson?

-Sanderson suggests that learning to program can be a great motivator for math, as it provides a practical application for mathematical concepts and can spark interest in those who may not have previously enjoyed math.

### What is Sanderson's advice for someone who wants to deepen their understanding of a mathematical concept?

-Sanderson recommends creating videos or actively trying to explain the concept to others, as teaching or actively interacting with the material can significantly enhance knowledge retention and understanding.

### What is the significance of actively engaging with math problems rather than just watching lectures?

-Actively engaging with math problems helps to consolidate knowledge and is more effective for learning than passive activities like watching lectures or reading.

### How does Sanderson describe the learning process when one is watching educational videos without associated exercises?

-He describes it as a partial part of the learning process, implying that additional active engagement with problems is necessary for comprehensive understanding.

### What is the generalizable path that Sanderson speculates might lead people who didn't like math to get into programming?

-Sanderson speculates that getting into programming can turn people on to math, especially if they find a practical application or motivation for the mathematical concepts through programming.

### What is the percentage of knowledge retention associated with teaching according to the numbers Sanderson mentions?

-According to the numbers Sanderson mentions, teaching retains about 90% of the knowledge.

### Why does Sanderson think that actively explaining or teaching a concept is beneficial for learning?

-Sanderson believes that actively explaining or teaching a concept is beneficial because it helps to consolidate the knowledge, leading to a deeper understanding and better retention of the material.

### What is the importance of working through exercises at the end of a textbook chapter?

-Working through exercises at the end of a textbook chapter is important because it allows learners to apply what they have read, test their understanding, and identify areas where they may need further study or clarification.

### Outlines

### π Effective Math Learning Strategies

The paragraph discusses the best methods for learning math, especially for beginners.
