Higher algebra is an important branch of mathematics, which mainly studies the concepts of linear equations, matrices, vector spaces, groups, rings and fields. Abstract algebra is a sub-field of higher algebra, which mainly studies abstract structures, such as groups, rings and fields.

Learning advanced algebra and abstract algebra requires a certain mathematical foundation, including elementary algebra, analytic geometry and calculus. In the process of learning, you can adopt the following methods:

1. Reading textbooks: Choose a good textbook and study it systematically in the order of textbooks. For example, you can refer to Qiu's Advanced Algebra.

2. Doing problems: Doing problems is an important means to consolidate knowledge. You can choose exercises from textbooks to do, or you can download some problem sets from the Internet.

3. Participate in discussion classes or remedial classes: If possible, you can participate in some discussion classes or remedial classes to discuss problems with teachers and classmates and deepen your understanding of knowledge.

4. Use network resources: There are many learning resources about advanced algebra and abstract algebra on the network, which can be used to assist learning. For example, you can watch some teaching videos about Bili Bili.

5. Make more summaries: In the process of learning, you should always make some summaries and organize what you have learned into a frame diagram or mind map to help you better understand and remember.
