# Algebra I

Algebra is the language through which we describe patterns. Think of it as a shorthand, of sorts. As opposed to having to do something over and over again, algebra gives you a simple way to express that repetitive process. It's also seen as a "gatekeeper" subject. Once you achieve an understanding of algebra, the higher-level math subjects become accessible to you. Without it, it's impossible to move forward. It's used by professionals of all kinds, not just college-bound ones. In these tutorials, we'll cover a lot of ground. Some of the topics include linear equations, linear inequalities, linear functions, systems of equations, factoring expressions, quadratic expressions, exponents, functions, and ratios.

#### Introduction to algebra

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

#### Linear equations

#### Linear inequalities

Exploring a world where both sides aren't equal anymore!

#### Graphing and analyzing 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.

#### Quadratic 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 proportions

What ratios and proportions are. Using them to solve problems in the real world.
