The topic summary outlines matrix algebra. Some topics reviewed are operations with matrices, matrix inverse, and algebra of matrices. The resource consists of definitions, notes, and examples.

Hotmath provides 21 practice problems dealing with systems of equations and inequalities. Each of the practice problems include a step-by-step guide for solving their algebraic problem.

Represent systems of two linear equations with matrix equations by determining A and b in the matrix equation A*x=b. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video, or receive hints.

Students explore the inverse of a square matrix. Topics examined are the inverse of a real number, using inverses to solve systems, and the determinant of a 2 x 2 matrix. Class notes and examples are included.

This site from the Richland Community College provides the detailed lecture notes to a college algebra course, complete with equations and definitions. Content ranges from "functions and their graphs" to "conics and parametric equations."

Dozens of statistical terms are defined and illustrated in this glossary.
