# Algebra - Functions, Expressions and Equations

## Learn more about Algebra calculations, including expressions, equations, and variables, in a clear and simple manner.

## Description

An algebraic expression is a mathematical phrase that can contains ordinary numbers, variables such as x or y, and operators such as add, subtract, multiply, and divide. This course begins by discussing expressions and variables. You will learn how to compose expressions, equations, and inequalities. You will then study distributive properties and learn how to solve ratios and proportions. You will also study how to calculate with percentages. This course will also discuss linear equations in the coordinate plane and the slope-intercept form of a linear equation.

You will then study parallel and perpendicular lines, scatter plots, and linear models. You will learn how to solve linear inequalities, compound inequalities, and absolute value equations and inequalities. This course will also teach you about graphing linear systems, the elimination method for solving linear systems, and the substitution method for solving linear systems. You will also look into the properties of exponents and exponential growth. You will then look into monomials, polynomials, special factors of polynomials, and the polynomial equation in factored form.

Algebra is an important life skill since it moves us beyond basic math and prepares us for statistics and calculus. Upon the completion of this course, you will be able to use graphing to solve quadratic equations, simplify radical equations, simplify and multiply rational expressions, add and subtract rational expressions, and solve rational expressions. So, check out the course today, and start making algebra a lot easier!
