Algebra is a branch of mathematics that consists of rules and procedures for manipulating numbers. The first person to use the symbol x to represent an unknown number was Rene Descartes in 1637. He also wrote that “to find the value of ‘x’ for any given starting point. “Algebra has changed over time.

Are you wondering about the types of algebra and their functionalities? So, this article is for you as it will discuss 23 different types of algebra.

**23 Types Of Algebra That You Might Not Know**

Algebra is used across many disciplines including science, engineering, business, economics, etc. Babylonians made arithmetic and algebraic notation very popular and widely used. Today, many types of algebra focus on different concepts depending on the intended applications.

For example, linear algebra deals with the study of vector spaces while abstract algebra is more theoretical. Following are the 23 types of algebra.

### 1. Abstract Algebra

Abstract algebra is the study of algebraic structures. In particular, it studies groups, rings, fields, and vector spaces intending to find general methods for solving equations. Abstract algebra provides a powerful toolset to study real-world problems. For example, abstract algebras have been used in physics to solve difficult problems such as classifying all possible symmetries of a particle.

### Fields

Abstract algebra has many subdisciplines. Two of the most popular are ring theory and field theory. They are considered different areas because they focus on different concepts.

- Ring
- Group
- Vector Space

### 2. Linear Algebra

Linear algebra is the study of vector spaces and linear transformations. Vector spaces are mathematical structures in which you can add or subtract two vectors. Linear transformations are differentiable maps that send a vector in one vector space to another vector space, these maps must be additive inverses or have an inverse that is also a linear transformation. The first person to use the term “linear algebra” was Peano in 1888.

### Fields

Linear algebra has many fields, for example

- Differential Linear Algebra
- Matrix Algebra
- Group Linear Algebra
- Finite-Dimensional Vector Spaces
- Geometric Linear Algebra
- Tensor Analysis With Applications In Mechanics And Physics
- Linear Transformations in a vector space

### 3. Geometry Algebra

The main purpose of geometry is to answer the question “How are points, lines, and planes related in space?” Geometry has many different branches including Euclidean geometry, projective geometry, and finite geometry.

They all have different approaches but all of them attempt to get a better understanding of space.

### Fields

Geometry algebra is a branch that focuses on spatial objects and their properties. It makes use of both Euclidean geometry and coordinate geometry giving it an advantage over other branches, for example, the ability to represent the location of an object in space using coordinates. Some of the most important fields of geometry algebra are

- Affine Geometry
- Differential Geometry
- Differential Forms In Algebraic Topology
- Elementary Differential Geometry
- The Clifford Algebra-Applications And Examples Volume 1

### 4. Boolean Algebra

The purpose of Boolean algebra is to develop a system that has the properties of set theory and logic. It was derived from propositional calculus which is used in mathematics, philosophy, linguistics, and computer science.

This branch discusses how variables can be combined to form expressions. For example, the expression (a+b)∨(a-b) would be considered to be equivalent to (a+b)∧(a-b). The first person who used Boolean algebra was George Boole, an English mathematician.

### Fields

Boolean algebra has many fields including

- Combinatory Logic
- Logic Algebra

### 5. Topology Algebra

Topology is the study of properties that are preserved under continuous deformations of objects. This is a branch of math that uses algebra to study topological spaces. A very big part of topology is a thing called homotopy, which is a way of measuring the “distance” between two continuous functions from one space to another.

In topology, we can take some data and send it on a roller coaster ride, which will impact it in a way that we can’t imagine. This is a huge field of abstract mathematics with applications to computer science and economics. It’s an important part of modern physics too, especially quantum computing.

It can be used to represent data that has multiple states, such as the speed of a car being slightly over the speed limit.

This type of algebra uses fuzzy sets which are multisets that have a membership grade between 0 and 1. The first person to use these types of concepts was Lotfi Zadeh, who is best known for creating fuzzy logic.

This branch of abstract algebra is mostly used in mathematics, physics, and engineering. It studies rings, modules over a ring, vector spaces, associative algebras, and Lie algebras. A ring is an additive group with unity for which you can multiply elements together to get other elements in the group.

A module is a ring that has some direct summand or factor that can be considered to be its subring. An associative algebra is a vector space with an additional multiplication operation that makes it into a ring, which allows you to do matrix operations without changing the result of the calculation. Vector spaces have infinite dimensions, which means they, abstract groups. To do so, you must use an associative algebra that is also unital.

### Fields

These fields all relate to advanced algebra. They include

- Lie Theory And Lie Algebras

## Types Of Algebra – Conclusion

As you can see, there are many types of algebra, and they’re used in different areas. However, these branches tend to overlap and influence each other at the same time. This makes it difficult to study them separately.

What we can say for sure is that algebra allows us to solve problems that we wouldn’t be able to do otherwise, and its importance is increasing in modern sciences. This makes studying the different branches of algebra very important for students who want to be able to understand discoveries and theories, or even contribute new ones.
