How to Become Good at Math: A Personal Journey

Introduction

• Speaker: Han, a graduate of Columbia University in Math and Operations Research.
• Common perception: Math is for those with high IQ and natural talent.
• Reality: Anyone can become good at math through practice, regardless of past experiences.

Personal Story

• Initially struggled with math in high school.
• Experienced math anxiety and frustration in classes.
• Assumed to be "stupid" due to poor performance, but later realized the importance of practice.

Understanding Learning Methods

Passive Learning vs Active Learning

• Passive Learning: Involves receiving information without engagement (e.g., listening to lectures, reading).
• Active Learning: Engaging with the material through practice, discussion, and teaching others.
• Research shows active learning is more effective in math and science.

Importance of Practice

• Real-life math application: solving problems like calculating tips.
• Understanding concepts through practice rather than just reading.

Effective Practice Strategies

1. Mental Walkthrough: Before solving, visualize the steps needed to solve the problem.
2. Understanding Answers: If stuck, look at the answer first to understand the solution process.
3. Independent Practice: After reviewing the answer, attempt to solve the problem independently.
4. Repeat as Necessary: If incorrect, review the answer again and try until correct.

Study Tools and Techniques

• iPad for Study: Uses for note-taking and problem-solving.
• Paperlike Screen Protector: Mimics the feel of paper for a better writing experience.

Efficiency in Practice

• Saves time by understanding answers instead of struggling with confusion.
• Emphasis on understanding rather than just memorization.

The Feynman Technique

• Explain concepts to someone else (preferably someone without prior knowledge) to test understanding.
• Simplifying explanations indicates a strong grasp of the material.

Overcoming Math Anxiety

• Belief in one's ability to improve is crucial.
• Math anxiety is common; understanding builds confidence.

Building a Strong Foundation

• Math concepts build on each other; prerequisites are important.
• If confused, likely due to missing fundamental knowledge.

Processing Information

• Slow Brain vs Fast Brain:
  • Slow brain focuses on reasoning and problem-solving.
  • Fast brain relies on intuition and pattern recognition.
• Familiarity through practice helps quick recognition and solving of math problems.

Conclusion

• Becoming good at math requires practice and belief in oneself.
• Recommendations: Engage actively, practice regularly, and use effective learning techniques.
