Onion mathematics is based on the in-depth study of the mathematical knowledge system, and all the knowledge points of junior high school mathematics are divided in detail. It only takes about 5 minutes for each video to talk about a knowledge point. Incorporate more humorous plots, interesting animations and rich extended knowledge, and use multimedia interactive technology to improve learning efficiency. Onion Mathematics will also try its best to inspire students when watching video content-for example, the whole knowledge of science has a logical system, so students should try their best to understand the complete logical system rather than a single concept.
