Conceptual videos and worked examples from basic algebra through algebra 2. Includes videos from the former algebra worked examples playlists.
Introduction to algebra
Videos exploring why algebra was developed and how it helps us explain our world.
- Linear equations (85 videos)
Exploring a world where both sides aren't equal anymore!
Graphing linear functions
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
Solving a system of equations or inequalities in two variables by elimination, substitution, and graphing.
Multiplying and factoring expressions
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.
Quadratics functions and equations
In this topic, we'll analyze, graph and solve quadratic equations.
Exponent expressions and equations
Solving exponential and radical expressions and equations. Using scientific notation and significant figures.
Identifying, solving, and graphing various types of functions.
Ratios and rational expressions
You have probably been wondering whether our powers of algebraic problem solving break down if we divide by the variable or we have entire expressions in denominator of a fraction. Well, they don't! In this topic, you'll learn how to interpret and manipulate algebraic ratios and rational expressions (when you have one algebraic expression divided by another)!
Log-a-what? No, this tutorial is about neither chopped wood nor music (actually logarithms do have applications in music), but it is fascinating nonetheless. You know how to take an exponent. Now you can think about what exponent you have to raise a number to to get another number. Yes, I agree--unstoppable fun for the whole family. No, seriously, logarithms are used everywhere (including to measure earthquakes and sound).
Identifying and graphing circles, ellipses, parabolas, and hyperbolas.
Understanding and solving matrices.
Imaginary and complex numbers
Understanding and solving equations with imaginary numbers.
