Algebra is the language through which we describe patterns and gives a simple way to express a repetitive process. These videos demonstrate and teach many algebra topics, including linear equations, linear inequalities, linear functions, systems of equations, factoring expressions, quadratic expressions, exponents, functions, and ratios.

Algebra Topics Covered By These Videos:
Introduction to Algebra – 61 videos
Videos exploring why algebra was developed and how it helps us explain our world.
Linear Equations – 86 videos
We will now equate two algebraic expressions and think about how it might constrain what value the variables can take on. The algebraic manipulation you learn here really is the heart of algebra.
Linear Inequalities – 26 videos
Exploring a world where both sides aren’t equal anymore!
Graphing and Analyzing Linear Functions – 97 videos
Use the power of algebra to understand and interpret points and lines (something we typically do in geometry). This will include slope and the equation of a line.
Systems of Equations and Inequalities – 70 videos
Solving a system of equations or inequalities in two variables by elimination, substitution, and graphing.
Multiplying and Factoring Expressions – 61 videos
This topic will add a ton of tools to your algebraic toolbox. You’ll be able to multiply any expression and learn to factor a bunch a well. This will allow you to solve a broad array of problems in algebra.
Quadratic Equations – 45 videos
In this topic, we’ll analyze, graph and solve quadratic equations.
