# Evaluating Algebraic Expressions Worksheet Answer Key

## Get to Know the Basics of Evaluating Algebraic Expressions

Algebra is a subject that requires students to develop and practice their problem-solving skills. One of the most important topics in algebra is evaluating algebraic expressions. To evaluate an algebraic expression, you must substitute a given value for the variable in the expression, then simplify the expression. This process is often referred to as “plugging in” a value for the variable. Evaluating algebraic expressions worksheet answer key is an important resource that can help students understand the concept better.

## Identify the Variables in an Algebraic Expression

Before you can evaluate an algebraic expression, you must first identify the variables in the expression. Variables are symbols that represent values that are not known yet. For example, in the expression x + 5, x is the variable. Once you know what the variables are, you can substitute any value for the variable and simplify the expression to get the answer.

## The Simplifying Process

Once you have identified the variables in an expression and substituted a value for the variable, the next step is to simplify the expression. This means you will use the Order of Operations to work through the expression and get the answer. The Order of Operations tells you the order in which you should simplify an expression. First, you should simplify any expressions within parentheses. Then, you should simplify any exponents. Next, you should multiply and divide from left to right and finally, you should add and subtract from left to right.
