Algebra I Conceptual videos and worked examples from basic algebra. Community Questions Get a personal path through Algebra I 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.
