A good order to take math classes is typically: algebra, geometry, trigonometry, precalculus, and calculus. However, this may vary based on individual school curriculum and student goals.
For those who are interested in more details
When it comes to taking math classes, it is important to have a good order in which to take them. The most common order is algebra, geometry, trigonometry, precalculus, and calculus. However, the specific order may vary based on the school’s curriculum and the student’s goals.
“As someone who’s been through this curriculum, I can say from experience that everything builds on what you learned before. If you try to skip ahead, you’re likely to find the material too difficult to understand,” says math teacher, Dan Meyer.
Here are some interesting facts about the order of math classes:

Algebra is considered the foundation of higherlevel math courses and is required for many college majors.

Geometry helps students develop logical reasoning and analytical skills, as well as providing a strong foundation for calculus.

Trigonometry focuses on the study of angles and triangles, and is commonly used in engineering, physics, and navigation.

Precalculus is designed to prepare students for calculus and other advanced courses, and covers a wide range of topics such as functions, logarithms, and graphs.

Calculus is a branch of math that deals with the study of derivatives, integrals, and limits, and is used extensively in science, engineering, and economics.
Here is a table summarizing the order of math classes:
Class  Description 

Algebra  The study of mathematical symbols and the rules for manipulating these symbols 
Geometry  The study of points, lines, angles, and shapes 
Trigonometry  The study of triangles and their properties 
Precalculus  Preparation for calculus and advanced math courses 
Calculus  The study of derivatives, integrals, and limits 
In conclusion, taking math classes in a specific order is essential for academic and career success. It is important to follow a curriculum that builds upon each class and provides a strong foundation for higherlevel math courses. As Meyer says, “math is a continuous process, with each class building on the one before it.”
There are other opinions on the Internet
The typical order of math courses followed by most students in high school is:
 Algebra 1.
 Geometry.
 Algebra 2.
 Trigonometry.
 PreCalculus.
 Calculus.
 Advanced Placement Classes.
The typical order of math classes in high school is:
 Algebra 1
 Geometry
 Algebra 2/Trigonometry
 PreCalculus
 Calculus
Despite that every college has its own track, there is a general order (which is often switched around). Here it is:
Typically Precalculus is completed by the end of high school.
Calculus I (Called AP Calculus AB by the College Board)
Calculus II (Called AP Calculus BC by the College Board)
Calculus III (Often called Multivariate or Multivariable Calculus)
Linear Algebra
Ordinary Differential Equations
Partial Differential Equations
That’s all for undergraduate. If you’re going into a math, physics, or engineering major you’ll learn all of this (in no particular order):
Tensor Calculus
Combinatorics
Statistics (often taken during high school or undergraduate)
Machine Learning
Answer in video
The video provides a webpage that is a great resource for students who want to take math classes online. The webpage offers quick access to lectures, textbooks, and assignments for various math courses, and includes information on course prerequisites and which majors require them. The creator also emphasizes the importance of doing assignments and reading textbooks, instead of just watching the lectures, to fully understand the material. Overall, this resource is helpful for those seeking to learn math online or get ahead in their math courses.

For example, you’ll start with the basics like adding, subtracting, dividing, and multiplying. Then, as you build on your knowledge, you can master harder subjects in math like algebra, geometry, and calculus. If you have no idea how to divide or add, then algebra will certainly be confusing.
