## 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.

- 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.
