### 1. How to Simplify Expressions with Integers

After watching this video lesson, you will be able to simplify any integer expression by following the order of operations. Learn what to watch for and in what order to do your operations.

### 2. Simplifying and Solving Exponential Expressions

What do we do with an exponent? In this lesson, we'll learn how to simplify and solve expressions containing exponents. We'll solve a variety of types of exponential expressions.

### 3. Negative Exponent: Definition & Rules

Negative exponents have caused problems for math students as long as they have been defined. This lesson will shed some light on the negative exponent: what it means and how to work with it in a math problem.

### 4. Negative Signs and Simplifying Algebraic Expressions

Don't let negative signs get you down. In this lesson, we'll stay positive as we practice simplifying algebraic expressions that have those tricky negative signs.

### 5. Practice Simplifying Algebraic Expressions

In this lesson, we'll practice simplifying a variety of algebraic expressions. We'll use two key concepts, combining like terms and the distributive property, to help us simplify.

### 6. How to Solve Fractional Exponents

Fractional exponents, or rational exponents, are a special breed of exponents. These exponents allow us to calculate radicals in a very simplistic way. Once we change radicals to fractional exponents we can use the exponent rules to simplify an expression.

### 7. How to Evaluate Expressions with Substitution

In this lesson, we will review the definition of an algebraic expression and order of operations. We will then look at how to evaluate algebraic expressions using substitution and practice the process on multiple examples.

### 8. The Distributive Property and Algebraic Expressions

The order of operations is great. But sometimes we need to bend the rules to simplify an equation. Fortunately, the distributive property gives us a scenario in which this is okay. Learn all about it in this lesson.

### 9. How to Simplify an Expression with Parentheses & Exponents

Watch this video lesson to learn how important it is to follow the order of operations. Learn what to do when you see parentheses and exponents in your math problems.

### 10. Combining Like Terms in Algebraic Expressions

When you have an algebraic expression that's much too long, it would be great if you could simplify it. That's when knowing how to combine like terms comes in. In this lesson, we'll learn the process of combining like terms and practice simplifying expressions.

### 11. How to Find the Least Common Multiple of Expressions

Would you like to learn an easy method for finding the least common multiple of expressions? In this lesson, we will look at sample problems with prime factorization (a product of prime numbers) to explain the steps.

### 12. How to Simplify Radical Expressions With Addition

Expressions involving radicals can look a bit daunting. In this lesson, we are going to look at how to simplify radical expressions using addition. We will look at some different examples and talk about the steps involved in this process.

### 13. Multiplying then Simplifying Radical Expressions

Multiplying 2 or more radical expressions uses the same principles as multiplying polynomials, with a few extra rules for dealing with the radicals. This lesson will teach you how to multiply and then simplify radical expressions.

### 14. Math Conjugates: Definition & Explanation

After completing this lesson, you will be able to describe the concept of math conjugates. You will also be able to write math conjugates and use them appropriately to solve problems.
