In mathematics, a variable is a symbol or letter that represents an unknown quantity or a value that can change. It is commonly used in algebra to represent numbers or values that are not specified. Variables are mainly used to create algebraic equations and solve mathematical problems.
Variables can be either independent or dependent. An independent variable is a variable that can be changed or controlled in an experiment or mathematical equation. It is typically represented by the letter “x” and is used to determine the value or outcome of the dependent variable.
On the other hand, a dependent variable is a variable whose value depends on the independent variable. It is usually represented by the letter “y” and changes as a result of changes in the independent variable.
Variables can take on a range of values and can be manipulated in mathematical equations to find unknown quantities. They allow us to solve problems and represent real-life situations mathematically.
