- Some people assume that evaluating expressions only involves numbers and variables, but it can also involve constants and functions.
- A common pitfall is prioritisng addition over subtraction when multiple operations are present.
- Additionally, some individuals may overlook the importance of parentheses in altering the order of operations.
So, what exactly is evaluating an expression? In basic terms, it's the process of simplifying mathematical expressions by following the order of operations (PEMDAS). When you're given an algebraic expression, your goal is to evaluate it by applying arithmetic operations, such as addition, subtraction, multiplication, and division, in the correct order.
Risks and Opportunities
An expression is a mathematical statement with one or more terms separated by an operator, while an equation is a statement where an expression is set equal to another expression or value.

This involves variables, exponents, and multiple arithmetic operations, making it an example of a complex expression.
You can use the popular mnemonic PEMDAS, which stands for Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction.
While evaluating expressions offers many benefits, there are also potential challenges to consider. Individuals may struggle with understanding the correct order of operations or identify complex expressions. Fortunately, resources like practice problems, interactive tools, and online courses can help alleviate these difficulties.
To simplify this process, let's consider a basic expression: 2x + 5 - 3x. Using the correct order of operations, we first perform the multiplication and division, and then the addition and subtraction. This would yield the following result: -x + 5. In other words, we've successfully evaluated the expression.
