Variables in mathematics are symbols representing changing values, not fixed numbers. They play a crucial role in algebraic expressions and equations, allowing for the representation of unknown quantities and relationships between variables.
Variables in mathematics are symbols used to represent changing values. They are not set values and can be used to denote unknown quantities. Variables are essential in algebraic expressions and equations.
While more than one variable can be used in an equation, variables are not treated like numbers; they stand for values that can vary, and they cannot be used like constants. Variables, including fractions, are widely used in mathematical equations to represent relationships between quantities and to solve complex problems effectively.
