### 1. How to Solve Exponential Equations

Read this lesson to learn the steps you need to take to solve exponential equations. You'll see that it's not too difficult; you just need to make use of one other mathematical operation in order to solve your problems.

### 2. Calculating Rate and Exponential Growth: The Population Dynamics Problem

You know how the world population keeps increasing? It's increasing faster now than it was 100 or 1,000 years ago. In this lesson, learn how differential equations predict this type of exponential growth.

### 3. Lead Coefficients of Completing the Square

Quadratic equations are used in many areas. This lesson will teach you how to solve them by completing the square, using real-world examples where the lead coefficient is not one.

### 4. Complex & Irrational Roots: Definitions & Examples

This lesson defines complex roots, irrational roots and quadratic equations. Examples of how to solve quadratic equations with complex and irrational solutions are provided.

### 5. How to Use the Quadratic Formula to Find Roots of Equations

In this lesson, we'll look at quadratic equations and learn how to find the roots of these equations using the quadratic formula. We'll use the definition and some example to become comfortable using this invaluable tool.

### 6. How to Solve Quadratics That Are Not in Standard Form

It isn't always the case that your equation will be set up nicely for you to solve. In this lesson, learn how to factor or use the quadratic formula to solve quadratic equations, even when they are not in standard form.

### 7. How to Find Simple Interest Rate: Definition, Formula & Examples

When we borrow a certain sum of money over a period of time, we agree that we will pay it back, along with a fee, known as the interest owed. Similarly, when we invest a sum of money in a savings account, the account earns us interest. This lesson will show you how to calculate a certain type of interest called simple interest.

### 8. Compounding Interest Formulas: Calculations & Examples

Compound interest is a great way to have your money work for you. In this lesson, find out the formula for calculating compound interest and practice using the formula with several examples.

### 9. Finding Compound Interest With a Calculator

Compound interest is a type of interest many of us will encounter in our lives. This lesson will show formulas for different types of compound interest, and explain how to break the formulas down so we can use a calculator to find compound interest.

### 10. Markup & Markdown: Calculation & Examples

After watching this video lesson, you will become familiar with how stores price their products to make a profit. Learn about how they increase their prices, markup, and how they decrease their prices, markdown.

### 11. How to Solve Problems with Money

Money matters, and knowing how much things cost will be useful no matter where you go. In this lesson, we'll learn the steps for solving word problems involving money.

### 12. Using Equations to Solve Age Problems in Math

Word problems can be overwhelming because they contain lots of information. In this lesson, you will learn how to use equations to solve word problems.

### 13. Using Equations to Solve Chemical Mixture Problems

Science and math are like siblings. Where you find one, you may find the other. When solving chemical mixture problems knowing about percent concentration and systems of equations is a must. This lesson will show the mathematical applications for determining the amount of acid in a mixture.

### 14. Parabolas in Standard, Intercept, and Vertex Form

By rearranging a quadratic equation, you can end up with an infinite number of ways to express the same thing. Learn about the three main forms of a quadratic and the pros and cons of each.
