Provides plain-language tutorials for college level algebra. It also has mini-tests with answer keys that can be used to test your comprehension.

Algebraic Combinatorics (ALCO) is a mathematics journal that published its first issue in January 2018. It is committed to non-APC Open Access publishing, with no fees for authors or readers. ALCO was founded in 2017 when the full editorial board of the SpringerNature-owned Journal of Algebraic Combinatorics resigned. URI supports the journal's production costs through the Lyrasis Open Access Community Investment Program.

Highlights applications of geometry in the real world and in programming.

Provides a list of links on computational geometry and is recommended by the math department.

Provides online help for some calculus problems and algebra work; requires an account for more advanced calculations, but is good for basic work.

Contains several links, example tests, and formulae. Calculus.org is useful as a general resource center for studying calculus.

Provides a brief review of several common calculus topics.

This is an online textbook for multivariable calculus recommended by the Math Dept.
