### 1. How to Add and Subtract Like Fractions and Mixed Numbers

When adding and subtracting fractions, you must be sure to have a common denominator. Once you have a common denominator, you just add or subtract your numerators and then your whole numbers. Learn how in this lesson.

### 2. How to Add and Subtract Unlike Fractions and Mixed Numbers

Simple fraction arithmetic gets a little more complicated when our denominators don't match. In this lesson, we'll learn how to add and subtract unlike fractions. Then, we'll do the same with mixed numbers.

### 3. How to Add & Subtract Fractions with Denominators of 10, 100 & 1,000

In this lesson, we will see how to add and subtract fractions with denominators of 10, 100, and 1000. After learning how to do this, we will look at a couple of real life examples and apply the process of solving to these problems.

### 4. Multiplying Fractions with Whole Numbers

After watching this video lesson, you will know how to multiply any fraction with any whole number. Learn the one simple rule that will tell you which numbers you need to multiply to get your answer.

### 5. Multiplying Fractions and Mixed Numbers

Multiplying fractions is much more straightforward than adding, subtracting or dividing fractions. In this lesson, learn how it works. We'll also learn how to multiply mixed numbers.

### 6. Dividing Fractions and Mixed Numbers

Dividing fractions and mixed numbers? It sounds daunting, but it's not as tricky as it sounds. In this lesson, we'll learn how to divide fractions and mixed numbers.

### 7. How to Solve Complex Fractions

Did you know fractions can nest within fractions? In this lesson, we'll learn about complex fractions and look at two different methods for solving them.

### 8. Addition, Subtraction, Multiplication, and Division with Decimal Notation

Performing operations such as addition, subtraction, multiplication and division has some differences when there are decimals involved. This lesson will explain how to perform these operations all while keeping the decimals straight.

### 9. Practice with Fraction and Mixed Number Arithmetic

Adding whole numbers is one thing. But adding fractions and mixed numbers? That's not so simple. Or is it? In this lesson, we'll practice arithmetic with both fractions and mixed numbers.

### 10. Estimation Problems using Fractions

When working with fractions, estimating can save time and effort while getting you very close to the correct answer. In this lesson, we'll learn how to use estimation to quickly solve problems involving fractions.

### 11. Solving Problems using Fractions and Mixed Numbers

Fractions don't just live in math problems. They're all around us, helping us through our lives. In this lesson, we'll look at real scenarios where your ability to work with fractions can save the day.

### 12. How to Add Three or More Fractions with Like & Unlike Denominators

Fractions are everywhere. You might use them when you cook or when you share items with friends and family, even if you don't realize it. In this video, we'll explore how to add three or more fractions with unlike denominators.

### 13. Finding a Missing Numerator or Denominator in Addition & Subtraction Sentences

Having trouble finding missing numerators and denominators in fraction addition and subtraction number sentences? Learn how to find that missing number and solve the equation in this lesson on fraction addition and subtraction number sentences.

### 14. Solving Inequalities with Addition & Subtraction of Fractions

In this lesson we will break down inequalities into their basic steps to help make them easier to understand. We'll talk about what each symbol means and how basic math skills work together to make inequalities easy to work through.
