Writing algebraic expressions can be confusing for some. Use this lesson on writing algebraic equations to help you better understand them.

### Introduction

If you're learning algebra in school or are studying for a test, you've probably notice that many problems ask you to translate **written words** into **algebraic expressions**. In other words, there are plenty of **word problems**.

Some word problems have real-life details—almost like a short story. Others are simple, like descriptions of a math problem. We'll start with simple word problems, then move on to slightly more complex ones.

#### Writing simple expressions

Before you can tackle complex word problems, you need to learn how to translate simple problems into algebra. Watch this video from Khan Academy to learn how:

As you can see in the video, you can translate word problems into math problems by replacing the words with **operators** that mean the same thing. So for instance, **four divided by ***x* could be 4 ÷ *x*. **÷ **and **/ **are just two ways of writing **divided**.

#### Words commonly used in algebra problems

Here are some of the most common math words you'll see:

Many of these are probably familiar to you in everyday conversation. For instance:

**3 more than 2** is equal to **3 + 2**.**Twice as much** could be written as **2 ⋅ ****x**, or **2***x*.- Have you ever
**split** a check among three people? You could represent the amount of the check with the variable *c*, and write out that situation as *c* / **3**.
