Online Math Courses for Credit

Free math courses are available online and don't require students to register or pay tuition, but most of these courses also don't lead to college credit. Students who prefer to earn credit for the courses they take online might consider seeking out courses that charge a fee in exchange for access to online lessons. Fee-based classes can prepare students to earn alternative forms of credit. offers this form of online learning with short, engaging video lessons and self-assessment quizzes available to registered members. also offers free transcripts for its video lessons. Both of these options can lead to college credit. Students interested in math can check out the Math 102: College Math course and find lessons on these topics and more:

  • Linear Equations - Examine standard form, slope and the system of equations and learn how to graph and write an equation.
  • Complex and Imaginary Numbers - Learn how to add, subtract, multiply and divide complex numbers.
  • Properties of Functions - Find out about conditions for a function, transformations, domain and range and inverse functions.
  • Probability and Statistics - Learn how to calculate percent increase, mean, median and range while learning about standard deviation, probability of complementary events and permutations.

Another option for math students is's Math 101: College Algebra course, which includes such topics as:

  • Matrices and Absolute Values - Learn how to evaluate absolute value expressions and solve and graph absolute value equations.
  • Exponents and Polynomials - Get details on the five main exponent properties, rational exponents and using synthetic division to divide polynomials.
  • Exponentials and Logarithms - Find out about exponential functions and logarithmic properties and practice with the sample problems in this chapter. also offers Math 104: Calculus. Some of the lessons in this course include:

  • Continuity - Learn about continuity in a function, discontinuities and intermediate value theorem.
  • Rate of Change - Examine velocity, slopes, the mean value theorem and derivatives.
  • Integration Applications - See methods for finding simple areas and areas between functions and calculating volumes using single intervals.

Maths Everywhere at The Open University

The UK's Open University offers a wide variety of mathematics and statistics courses online. The courses are free to everyone regardless of location. Maths Everywhere is an introductory math course that's divided into three segments with various tasks, illustrations and assignments. The course follows content in the Tapping into Mathematics textbook and practices math using a Texas Instruments TI-83 graphics calculator.

Algebra I at Massachusetts Institute of Technology (MIT)

There are nearly 100 free general mathematics courses available through MIT's OpenCourseWare (OCW) project. Most of the courses consist of lectures, slides, problem sets, assignments and other resources to assist in self-study. Registration is not required. This OCW course covers basic topics in algebra such as groups (including linear and symmetry groups) vector spaces, linear transformations and bilinear forms.

xyAlgebra 7.0 and xySolver 7.0 at xyAlgebra

John Miller, a professor emeritus of the City College of New York (which is part of the City University of New York, or CUNY) is the creator of xyAlgebra software. The copyrighted software, which allows students to practice and learn algebra, can be downloaded for free. Features include interactive instruction and practice problems. This software is ideal for students who'd like to improve their algebra knowledge and for math teachers looking for additional resources to help their students.

Calculus I at University of Massachusetts, Boston

Through the OpenCourseWare project, UMass offers a series of three calculus courses, each providing comprehensive instruction in the subject. The downloadable courses include multiple lessons, suggested problems, reading assignments and much more. Registration is not required.

Calculus on the Web (COW) at Temple University

Members of the mathematics department at Temple University designed a library system that they coined Calculus on the Web (or COW) to help students learn and practice calculus. The COW system is composed of interactive modules that students can use to learn about calculus and related math topics, such as precalculus, calculus, linear and abstract algebra, and number theory. The modules include assignments that are graded automatically so students can check to see if they solved problems correctly.

Trigonometry at Whatcom Community College

Whatcom Community College offers a PDF version of their Trigonometry Unit lesson online. The 20-page PDF aimed at beginners includes an introduction to trigonometry, explanatory text and problem sets with answers. A free version of Acrobat Reader is required to view the document.

Solving Cubic Equations at Harvard University

This 45-minute video lecture from Harvard professors Benedict H. Gross and William A. Stein explores various mathematical theorems and cubic equations. The seven segments include slides, illustrative equations and a glossary of terms. The videos can be viewed using free versions of Real Player, QuickTime or Windows Media.
