Free Mathematics Courses | Algebra Through Differential Equations

Algebra

Master the foundational language of mathematics — variables, equations, functions, and graphs — so future math finally makes sense.

Build a strong understanding of trigonometry through structured video lessons, clear examples, and step-by-step problem-solving.

Build a strong precalculus foundation through functions, transformations, and the key concepts that prepare you for calculus.

Understand why calculus works — not just how to apply the rules for limits, derivatives, and integrals

See the geometry behind the algebra through vectors, matrices, and transformations that finally feel intuitive.

Understand what differential equations model, why the methods work, and how mathematics describes change.
