In mathematics, a variable is a symbol used to represent an unknown quantity or value that can vary or change

In mathematics, a variable is a symbol used to represent an unknown quantity or value that can vary or change. Variables are commonly represented by letters such as x, y, or z. They are used in mathematical equations, formulas, and expressions to denote unknown quantities that need to be solved for.

Variables are an essential part of algebra, where they are used to solve equations and manipulate mathematical expressions. They allow us to represent and work with unknowns or generality in mathematical problems.

For example, let’s say we have an equation:

2x + 3 = 10

Here, the variable x represents an unknown quantity. By solving the equation, we can find the value of x.

Variables can also be used in representing relationships between quantities. For instance, if we have an equation to calculate the area of a rectangle:

A = length * width

In this case, the variables length and width represent the unknown values, and we can substitute specific values to calculate the area.

It’s important to note that variables can take on different values depending on the context. They can be real numbers, integers, or defined in a particular set. The values of variables can be determined through calculations, measurements, or specified in a problem statement.

Variables are a fundamental concept in mathematics and are used in various branches such as algebra, calculus, and statistics. They enable us to analyze and solve mathematical problems more effectively by representing unknown quantities or relationships between variables.
