Simplifying and Evaluating Algebraic Expressions

Abstract

When you work with algebraic expressions, it's important to understand the different parts that make up each expression. Terms are the building blocks of an expression.

Description

To evaluate an expression when you're given the value of a variable, you simply substitute the number in place of the variable and then follow the order of operations (PEMDAS: Parentheses, Exponents, Multiplication/Division, Addition/Subtraction).
