A variable is a quantity that is represented by a letter. In mathematics, a variable is a symbol, often a letter, used to represent an unknown or changeable value. It can take on different values in a given context, making it essential for algebra and other areas of mathematics. In contrast, a fixed number without a variable is known as a constant.
