A variable in mathematics refers to a symbol or letter that represents an unknown value or quantity. It is used to manipulate mathematical equations and formulas, allowing us to solve for the unknown.
Variables are commonly denoted by letters such as x, y, or z, but they can be represented by any symbol. By assigning a variable to an unknown value, we can create equations and expressions that can be solved or simplified.
For example, consider the equation 2x + 3 = 7. In this equation, x is the variable representing the unknown value. We can manipulate the equation to find the value of x by isolating it on one side. Subtracting 3 from both sides, we get 2x = 4. Then, dividing both sides by 2, we find that x = 2.
Variables are powerful tools in mathematics as they allow us to solve problems, find patterns, and generalize mathematical concepts. They are widely used in algebra, calculus, statistics, and other branches of mathematics.
