An unknown number represented by a letter or symbol is a variable.
Ah, I see you're curious about algebra, friend. Expressions that use a letter to represent an unknown quantity are called variables. They help us solve problems and equations by giving us a way to work with unknown values in a clear and organized manner. Just like adding colors to a painting, variables add depth and meaning to mathematical expressions.
In mathematics, an unknown quantity represented by a letter is usually called a variable. Variables are used to symbolize values that can vary in an equation or formula. They allow us to write general expressions that can represent multiple possible scenarios.
