What Are Algebraic Expressions?
Definition and Components
- Algebraic expressions are mathematical phrases that combine numbers, variables, and operation symbols (such as +, –, ×, ÷).
- They do not contain an equal sign; instead, they represent a value that can be calculated or simplified.
- Variables are symbols (often letters) that stand for unknown or changing values.
Examples of Algebraic Expressions
- 3x + 5
- 2(a – 4) + 7
- x² + 2x – 8
What Does Evaluating Expressions Mean?
Definition of Evaluating
Evaluating an algebraic expression involves substituting specific values for the variables and then performing the operations to find a numerical answer. It transforms a symbolic expression into a real number based on given data.
Steps in Evaluating Expressions
- Identify the values assigned to each variable.
- Substitute these values into the expression.
- Follow the order of operations (PEMDAS/BODMAS) to simplify the expression.
- Calculate the result to find the final value.
