Abstract Algebra


If you are studying mathematics at the university level, chances are that you have come across abstract algebra and linear algebra. These two fields of mathematics may seem similar, but they have some fundamental differences that students frequently ask about. One of the most popular questions regarding these two fields is whether abstract algebra is harder than linear algebra. In this article, we will explore both fields and compare them to help you decide which one is more challenging.

Abstract Algebra vs Linear Algebra

Abstract algebra is a branch of mathematics that studies algebraic structures such as groups, rings, and fields. It is an advanced level course that requires students to have a solid foundation in other fields such as calculus and linear algebra. Linear algebra, on the other hand, is a branch of mathematics that concerns itself with linear equations, matrices, and vector spaces.

Linear algebra is often considered to be part of abstract algebra since it deals with vector spaces, which are groups, rings or fields when restricted to the operations of addition and scalar multiplication, respectively. However, linear algebra is more concrete with matrices, hence less abstract and easier to learn than abstract algebra.

In summary, linear algebra is a more focussed field and deals with more tangible, accessible objects like matrices while abstract algebra is a broader field and deals with more abstract algebraic structures like groups and rings.


1. What makes abstract algebra harder than linear algebra?

The main reason why abstract algebra is considered harder than linear algebra is because of the abstract algebraic structures it deals with, like groups and rings. These structures can be difficult to visualize, unlike matrices and vectors that are used in linear algebra. In abstract algebra, the concepts are more theoretical, and students generally need to think more abstractly to understand them.

2. Is linear algebra necessary for abstract algebra?

Yes, linear algebra is a fundamental subject that is essential for studying abstract algebra. It lays a solid foundation in vectors, matrices, and vector spaces, which students can use to understand more complex algebraic structures such as groups and rings. Abstract algebra requires an understanding of linear algebra, and it is not advisable to study abstract algebra without a strong background in linear algebra.

3. Which one is more useful in physics and engineering?

Linear algebra is more useful in physics and engineering than abstract algebra. Many branches of physics and engineering use linear algebra concepts like matrices and vectors to describe physical phenomena and analyze data. For instance, linear algebra is used in computer graphics and machine learning pattern recognition in engineering. Abstract algebra, on the other hand, finds applications in pure mathematics research, cryptography and coding theory, which isn’t as useful in physics and engineering.

4. Is abstract algebra only for pure math students?

Abstract algebra is a field of study that is relevant for pure mathematicians, but it is also useful for students in other fields, including physics, engineering, and computer science. Abstract algebra gives students the ability to think abstractly, solve complex problems and develop logical reasoning skills. These skills can be useful in various career fields and life in general.


Abstract algebra and linear algebra are both fascinating fields of mathematics. They have unique features that make them different from each other. Linear algebra is a more concrete approach to mathematics, while abstract algebra is more theoretical and abstract. Therefore, it cannot be said one is easier than the other, but linear algebra is less abstract, dealing with matrices and vectors, while abstract algebra utilizes algebraic structures like groups and rings. All in all, it is essential to have a solid foundation in both fields to excel in mathematics, and depending on your area of interest or career path, you could choose one over the other.
