Final answer:
In mathematics, any value that is unknown or can change is considered a variable. Variables are represented by letters or symbols and are used in equations or expressions to represent quantities that can vary.
Step-by-step explanation:
True, any value that is unknown or can change is considered a variable in mathematics. Variables are often represented by letters or symbols and are used to represent quantities that can vary or change in mathematical equations or expressions.
For example, in the equation y = mx + b, y and x are variables because they can take on different values depending on the specific problem or situation. The values of these variables can be determined through calculations or by solving the equation.
Understanding variables is important in various mathematical concepts and operations, such as algebra, geometry, and calculus.
