### 1. Simplifying Complex Rational Expressions

When it comes to fractions, things may seem to get really complicated and scary when you have a fraction on top of a fraction. But never fear, after watching this video lesson, you will be able to simplify these expressions like a pro.

### 2. How to Add and Subtract Rational Expressions

Adding and subtracting rational expressions brings everything you learned about fractions into the world of algebra. We will mix common denominators with factoring and FOILing.

### 3. Practice Adding and Subtracting Rational Expressions

Adding and subtracting rational expressions can feel daunting, especially when trying to find a common denominator. Let me show you the process I like to use. I think it will make adding and subtracting rational expressions more enjoyable!

### 4. How to Multiply and Divide Rational Expressions

Multiplying and dividing rational polynomial expressions is exactly like multiplying and dividing fractions. Like fractions, we will reduce. With polynomial expressions we use factoring and canceling. I also give you a little mnemonic to help you remember when you need a common denominator and when you don't.

### 5. Multiplying and Dividing Rational Expressions: Practice Problems

Let's continue looking at multiplying and dividing rational polynomials. In this lesson, we will look at a couple longer problems, while giving you some practice multiplying and dividing.

### 6. Simplifying Rational Expressions With Factoring

In this lesson, we will review rational expressions and factoring. Then, we will see how to use factoring to simplify rational expressions and actually put the process to use in an example.

### 7. Rationalizing Denominators in Radical Expressions

Radical expressions containing denominators are not simplified completely unless the denominator is free of radical symbols. This lesson will teach you how to remove a radical from the denominator of a fraction through a process called rationalizing the denominator.

### 8. How to Simplify Complex Fractions

When fractions are inside other fractions, it can get really confusing. In this lesson, we'll learn how to tackle complex fractions, using the tools math gives us to simplify and resolve the toughest ones.

### 9. Simplifying Complex Numbers: Addition of Like Terms

We will talk about complex numbers - their uses and their parts. Then, we will look at simplifying these types of numbers by adding like terms. Lastly, we will practice this process through various examples.

### 10. Simplifying Complex Numbers: Euler's Notation

Sometimes things in math get a little complex, especially when you're dealing with complex numbers. In this lesson, you'll learn how to simplify things using a nice way to represent complex numbers: Euler's Notation.

### 11. Simplifying Complex Numbers: Conjugate of the Denominator

Calculations with complex numbers sometimes produce a complex number in the denominator. In this lesson, we show how to simplify these results by using the complex conjugate.

### 12. Simplifying Complex Numbers With Multiple Steps

Performing the basic operations with complex numbers isn't much different than doing so with polynomials. In this lesson, we'll go over what exactly you must know about complex numbers, including some key facts that'll help you perform these operations.

### 13. Simplifying Complex Numbers With Multiplication & Division

In this lesson, we'll review the definition of complex numbers. With the aid of illustrations, we'll also look at the steps involved in simplifying complex numbers with multiplication and division.
