Text Lessons:

• Absolute Value - An absolute value is a number's distance from the origin.
• Addition and Subtraction of Rational Functions - Explains how to add or subtract rational functions, which involve complicated fractions.
• Asymptotes - Defines asymptotes and then shows how to find them visually and algebraically.
• Combining Like Terms - A method to help simplify an algebraic expression to combining terms wherever possible.
• Completing the Square In Circle Equations - The equations for circles can often be complicated, so completing the square offers one method to simplify such equations.
• Direct Variation - Two variables that are related such that when one increases the other increases in the same proportion are said to directly vary.
• Distributive Property - This property allows you to simplify expressions with parenthesis multiplication.
• Division of Rational Functions - Very brief example of dividing complicated rational functions.
• Domain and Range - Domain and range are basically the values that can be plugged into a function and the possible outcomes.
• Exponential Functions - Covers functions with exponential terms, including exponential growth.
• Factoring Numbers - Learn how to find the factors of a number. Factors are numbers which evenly divide a certain larger value.
• Finding Asymptotes - Quick lesson on factoring a function to reveal its asymptotes.
• Finding Horizontal Asymptotes - A short discussion of finding horizontal asymptotes created when the domain goes towards infinity.
• Finding Limits - A limit is a certain value that a function approaches.
• Finding Roots - Find the roots of an equation (points where the function equals zero).
• Functions - Definition and brief introduction to functions.
• Greatest Common Factor - Learn how to find the largest number that evenly divides another number.
• Imaginary Numbers - Imaginary numbers help us solve problems when square roots of negative numbers are involved.
• Introduction to Algebra - A very basic overview of some of the concepts to be learned in algebra.
• Length of a Line Segment - Calculate the length of a line segment by using the distance formula.

• Multiplication of Rational Functions - Covers the multiplication of rational functions.
• Multiplying Polynomials - Lesson covers the basics of multiplying polynomials using the foil method.
• Negative Exponents - Learn how to solve problems involving negative exponents.
• Order of Operations - Lesson on the order of operations, which determines whether you add, subtract, multiply, divide, etc. first in an expression.
• Point Slope Form - The point slope form is a standard way of defining a line algebraically.
• Proportions and Ratios - Proportions and ratios are helpful in solving simple problems with fractions.
• Rational Functions - These are functions written in complicated fractional form.
• Real Numbers - Real numbers are most usual numbers. This lesson covers basic types, including rational and irrational numbers.
• Scientific Notation - Scientific notation is a method for writing really large or really small numbers in an easy to understand notation.
• Solving Systems of Inequalities - Lesson on solving more than one inequality at the same time.
• Substitution - Learn to substitute values for variables, and also simplify expressions by substituting variables for complex expressions.
• Systems of Equations With More Than Two Variables - Solve a system of linear equations that includes three or more variables.
• Systems of Linear Equations - Solve multiple equations with multiple variables.
• Using FOIL - Learn to expand parenthesis by using foil to multiply two binomials.
