In algebra, a letter, typically a variable like ( x ), ( y ), or ( z ), is used to represent an unknown number or value. This allows for the formulation of equations and expressions to solve mathematical problems. By manipulating these variables, one can find their specific values based on the relationships defined in the equations. This abstraction is fundamental to algebraic reasoning and problem-solving.
An unknown number
"n" stands for an unknown number.
A letter used to represent an unknown number is called a "variable." In mathematics, variables are often denoted by letters such as x, y, or z. They are used in equations and expressions to stand in for values that can change or are not yet known. Variables play a crucial role in algebra and various branches of mathematics.
