Full description
Linear algebra, one short lesson at a time. Matty Math turns linear algebra into a course you can actually finish. Instead of working through a 400-page textbook, you get short, focused lessons you can do on the train, in a queue, or in the ten minutes before a lecture. WHAT YOU LEARN - Vectors: notation, addition, scaling, dot products - Matrices: multiplication, transpose, inverse, determinants - Systems of linear equations and Gaussian elimination - Vector spaces, span, basis and dimension - Linear transformations and change of basis - Eigenvalues and eigenvectors HOW IT WORKS - Bite-size lessons, each built around a single idea - Practice rather than passive reading: every lesson is questions you answer - Immediate feedback, with a worked explanation when you get something wrong - Your progress is tracked lesson by lesson, so you always know what is next - Streaks to help you keep the habit going WHO IT IS FOR Students taking a first course in linear algebra. People moving into machine learning, data science or engineering who need the mathematics underneath it. And anyone who once learned this and would like it back. The mathematics is genuinely demanding. The lessons are just short.
