In this video, I introduced my memorization techniques for linear algebra, or in general, mathematics. I used to make up lots of stories to foster my memory. Here I selected 4 important topics in linear algebra and tried to use my perspective to tell the story.

In this video, I introduced the theory of coordinates, transformation matrices and B-matrices in linear algebra. This video focuses on presenting the notation I use, which I find it useful to parse in our mind. This aligns with the concept in computer science that we should name the variables such that it is easy to comprehend, instead of giving it a single letter name.

In this video, I introduced the subject of Linear Algebra. This video focuses on the motivation of learning linear algebra and my personal philosophy of learning maths at university level. No technical mathematical details are included. This video aims to motivate students to learn maths in a way such that examples and theories are emphasized over mundane calculations.

Since most of high school students have not received trainings for writing rigorous proofs, I decided to make this video so that students can understand the basic structures of proofs.
