Online Math Courses for Credit
There are several free math courses available online that you can explore without worrying about registration or tuition. But if you're looking for something that can help you receive college credit, you'll have to look elsewhere. Study.com offers comparatively cheap math courses that give you the chance to earn credit in mathematics, with lessons conducted by professional instructors that include both a video and transcript of the material.
For college-level content, you can look into Math 102: College Mathematics, which covers material such as linear equations, navigating graphs, working with rational expressions, and more. Some of the other chapters within this course include:
- Properties of Exponents - Topics dealt with include simplifying expressions with exponents, working with rational exponents, defining zero and negative exponents, and more.
- Complex and Imaginary Numbers - Within this chapter you can learn the ins and outs of dividing complex numbers, solving quadratics with complex numbers as the solution, and related mathematical terms and operations.
- Sets - Learn to navigate two-way tables, venn diagrams, subsets, and more.
- Logic - Here you'll find subjects such as conditional statements, propositions, logical equivalence, and related mathematical language.
Where Can I Find Free Online Math Classes?
Free online math classes are available through college and university OpenCourseWare programs, which provide access to undergraduate and graduate-level classes via materials that can include lectures and online assignments. Students might also be able to download multimedia content, such as webcasts, MP3s, audio streams, online textbooks, and lecture notes. In some cases, students can take advantage of online math tutoring systems that provide assistance with coursework. However, these courses do not award academic credit.
Massachusetts Institute of Technology
MIT offers several free math classes, with subjects ranging from linear algebra and calculus to wave propagation and nonlinear dynamics. Some additional course topics are outlined below.
- Multivariable Calculus covers such topics as matrices, vector algebra in 3-space, and line integrals in the plane. Other topics include Green's theorem, Stokes' theorem and the divergence theorem.
- Mathematics for Computer Science deals with introductory discrete mathematics geared towards computer science and engineering. It focuses on key mathematical terminology, proofs, and approaches to applying them. You'll look over topics like formal logic notation, sets, elementary graph theory, integer congruences, and much more.
- Introduction to Probability and Statistics takes a look at the basic applications of probability and statistics within mathematics. You'll delve into topics such as basic combinatorics, probability distributions, Bayesian inference, and linear regression.
