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 know how to translate simple problems into algebra.
Generally, you'll do this by replacing the words with operators that mean the same thing. 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.
Have you ever split a check among three people? Writing multi-part algebraic expressions Some expressions are slightly more complicated than the ones we looked at on the last page.
For instance, some expressions include more than one math operation. Take this one as an example: Your expression would look like this: This is because the order of operations would call for you to multiply 5 times 4 first, then add 2. However, our written expression asks us to multiply 5 by the sum of 4 and 2.
In other words, we need to add 4 and 2 first, then multiply that number by 5. If you're familiar with algebraic notation, you know that parentheses are useful in cases like this—they let you group part of an expression and solve it separately from the rest.
Here, we can use them to group 4 and 2—the numbers being added. Based on the order of operations, always solve operations in parentheses first. Assessment Want even more practice?

The expression 9 + x represents a value that can change. If x is 2, then the expression 9 + x has a value of If x is 6, then the expression has a value of So 9 + x is an algebraic expression.
In the next few examples, we will be working solely with algebraic expressions. Example 2: Write each phrase as an algebraic expression.
the expression. Evaluate the expression on the right side of the equation. Hourly wage = 12 ÷ 3 Write.
= 4 Evaluate.
So, your hourly wage is $4 per hour. 1 EXAMPLE: Reading and Re-Reading STATE STANDARDS MAA S Evaluating Algebraic Expressions 2 Chapter 1 Expressions and Number Properties How can you write and evaluate an expression.
