### 1. 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.

### 2. How to Use Newton's Method to Find Roots of Equations

Finding the roots of equations usually requires the use of a calculator. However, in this lesson you'll use Newton's Method to find the root of any equation, even when you can't solve for it explicitly.

### 3. 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.

### 4. 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.

### 5. 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.

### 6. 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.

### 7. 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.

### 8. 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.
