### Q & A

### What is the best way to learn math according to Grant Sanderson?

-The best way to learn math, according to Grant Sanderson, is to spend more time solving specific problems rather than just watching lectures or reading. He suggests focusing on problem-solving and using well-curated lists of problems from textbooks.

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

-Sanderson recommends this approach because it helps learners identify which problems they can solve and which ones they need to understand better. This method encourages active problem-solving and deeper understanding of the material.

### What does Sanderson admit about his own videos in the learning process?

-Sanderson admits that his videos are only a partial part of the learning process since they usually do not have associated exercises. He views his videos as a different part of the educational ecosystem.

### What online resource does Sanderson recommend for beginners in math?

-Sanderson recommends Khan Academy for beginners because it offers a large set of questions to work through and covers fundamental topics like basic linear algebra and calculus.

### How does Sanderson suggest using programming to learn math?

-Sanderson suggests learning to program and using the motivation from programming to push through math concepts. He notes that many people who were initially disinterested in math found a passion for it through programming.

### What does Sanderson say about the retention rates of different learning activities?

-Sanderson mentions a common anecdote that people remember about 10% of what they read, 20% of what they listen to, 70% of what they actively interact with, and 90% of what they teach. Although he acknowledges these numbers might not be accurate, they resonate with his experience.

### Why does Sanderson believe teaching or explaining concepts is beneficial for learning?

-Sanderson believes that teaching or actively explaining concepts helps in consolidating knowledge much more effectively than passive learning methods.

### Does Sanderson think creating educational videos like his own is beneficial for learners?

-Yes, Sanderson suggests that creating educational videos or trying to explain concepts can be a powerful way to learn, as it forces the learner to understand the material deeply enough to teach it.

### What role does active problem-solving play in learning math according to Sanderson?

-Active problem-solving is crucial in learning math according to Sanderson because it engages the learner more deeply with the material and helps in applying theoretical concepts practically.

### How can someone incorporate Sanderson's advice into their math study routine?

-Someone can incorporate Sanderson's advice by focusing more on solving problems, using resources like Khan Academy, integrating programming with math learning, and engaging in teaching or explaining concepts to others.

### Outlines

### π Embracing Active Learning in Mathematics

The paragraph emphasizes the importance of active learning for those beginning their journey in mathematics or even for those further along in their studies. It suggests that instead of passively watching lectures or reading, individuals should focus on solving problems. The speaker recommends seeking out textbooks with well-curated problems and engaging with them before and after reading the chapters. The advice is to not move on until exercises are attempted, highlighting the speaker's own hypocrisy for creating video content without associated exercises, suggesting that videos are only a part of the learning process. For beginners, resources like Khan Academy are recommended for their extensive question sets and basic introductions to subjects like linear algebra and calculus.

### π» The Intersection of Programming and Math

This section discusses the connection between programming and math, suggesting that learning to program can motivate an understanding of mathematical concepts. The speaker shares personal observations of individuals who developed an interest in math through programming, possibly due to the practical applications and real-world problems that programming presents. The paragraph also touches on the speaker's own approach to creating educational videos, using programming to illustrate mathematical ideas, and suggests that others might benefit from a similar method of teaching or explaining concepts to solidify their understanding.

### π£οΈ Teaching as a Powerful Learning Tool

The final paragraph delves into the concept that teaching is one of the most effective ways to learn, referencing a set of percentages that suggest retention rates for different types of engagement. While acknowledging the anecdotal nature of these percentages, the speaker believes in the truth behind the idea that actively teaching or explaining concepts significantly improves knowledge retention. The speaker encourages the practice of teaching as a method to consolidate learning, suggesting that it might even be more effective than reading or listening to lectures.
