# Introduction to Variables: The Building Blocks of Algebra
Variables are **symbols** used to represent unknown values in mathematical expressions and equations. They are often represented by letters like `x`, `y`, or `z`. Understanding variables is crucial because they allow us to create general solutions and models that apply to many situations, not just one.
## Why It Matters Variables make it possible to write equations that describe real-world situations. They help us solve problems where not all information is immediately known.
