Writing and evaluating expressions pdf

On this page, you will find Algebra worksheets mostly for middle school students on algebra topics such as algebraic expressions, equations and graphing functions. This page starts off with some missing numbers worksheets for younger students. We then get right into algebra by helping students recognize and understand the basic language related to algebra. The rest of the page covers some of the main topics you'll encounter in algebra units. In the past, you've evaluated numerical expressions by using the order of operations. We are going to use these same rules to evaluate algebraic expressions. What is an Algebraic Expression? An Algebraic expression is an expression that you will see most often once you start Algebra.

In Algebra we work with variables and numerals. A variable is a symbol, usually a letter, that represents one or more numbers. Thus, an algebraic expression consists of numbers, variables, and operations. Examples of Algebraic Expressions An algebraic expression consists of numbers, variables, and operations. Here are a few examples: In order to evaluate an algebraic expression, you must know the exact values for each variable.

Then you will simply substitute and evaluate using the order of operations. Take a look at example 1. Example 1 - Evaluating Algebraic Expressions Now, lets evaluate algebraic expressions with more than one variable. Don't forget to always use the order of operations when evaluating the expression after substituting.

Example 3 - Using the Fraction Bar as a Grouping Symbol If you are familiar with the order of operations, then evaluating algebraic expressions is quite easy! Just remember to substitute the given values for each variable and evaluate.

The next lesson in this unit is translating algebraic expressions.Evaluating Expressions with Decimals To evaluate an expression, follow these steps: The value of the expression is Evaluate x2 1 2x 2 x 4 3 for x 5 the expression for 3 hours.
