Here is a listing of all the material that is currently available online.
Preliminaries
Integer Exponents - In this section we will start looking at exponents and their properties.
Rational Exponents - We will define rational exponents in this section and extend the properties from the previous section to rational exponents.
Real Exponents - This is a short acknowledgment that the exponent properties form the previous two sections will hold for any exponent.
Radicals - Here we will define radical notation and relate radicals to rational exponents. We will also give the properties of radicals.
Polynomials - We will introduce the basics of polynomials in this section including adding, subtracting and multiplying polynomials.
Factoring Polynomials - This is the most important section of all the preliminaries. Factoring polynomials will appear in pretty much every chapter in this course. Without the ability to factor polynomials you will be unable to complete this course.
Rational Expressions - In this section we will define rational expressions and discuss adding, subtracting, multiplying and dividing them.
