Variables and Expressions

Writing Algebraic Expression Step 1: Identify key words Step 2: Define the variable Step 3: Work the problem out in words. Step 4: Write the algebraic expressions by plugging in the known values and the variable. Important key words to know.

Evaluating Algebraic Expressions You have learned the steps for evaluating an algebraic expression: Step 1: Rewrite the expression by replacing the variable with the value provided. Step 2: Perform the indicated operations using the order of operations (PEMDAS). And if it’s a word problem we add the following step: Step 3: Answer the question posed in the problem.
