Algebra

Introduction to algebra

Videos exploring why algebra was developed and how it helps us explain our world.

Linear inequalities

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.

Functions

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)!

Logarithms

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).

Conic sections

Identifying and graphing circles, ellipses, parabolas, and hyperbolas.

Matrices

Understanding and solving matrices.

Imaginary and complex numbers

Understanding and solving equations with imaginary numbers.
