In mathematics, a variable (from Latin variabilis, "changeable") is a symbol, typically a letter, that holds a place for constants, often numbers. [ 1 ] [ 2 ] [ 3 ] [ 4 ] [ 5 ] [ 6 ] One say colloquially that the variable represents or denotes the object, and that the object is the value of the variable.

A variable in Mathematics is defined as the alphabetic character that expresses a numerical value or a number. In algebraic equations, a variable is used to represent an unknown quantity. These variables can be any alphabets from a to z. Most commonly, ‘a’,’b’,’c’, ‘x’,’y’ and ‘z’ are used as variables in equations.

A Variable is a symbol for a number we don't know yet. It is usually a letter like x or y, but can be a symbol or word. A number on its own is called a Constant. A Coefficient is a number used to multiply a variable (4x means 4 times x, so 4 is a coefficient)
A variable is a character that has an unknown value and is represented by an alphabet or a letter. A variable can be any letter from ‘a’ to‘ z’. However, the most commonly used letters used as variables are a, b, x, y, and z . A coefficient is a numeric value multiplied by a variable.
Variables are an essential concept in mathematics that allows us to represent unknown values and solve equations. By understanding how to use variables in algebra, we can simplify complex problems and find solutions more efficiently. Examples of variables in math include x, y, z, a, b, c, and many others.
What is a variable? A variable is a box, and it exists to contain a value. Sometimes the value is already inside the box, and you have to figure out what that value is. Other times, the box is empty, and you get to pick the value to put inside. When did folks start using variables? Some Greeks used variables in their work back in the third century.
A variable is a quantity that may change within the context of a mathematical problem or experiment. Typically, we use a single letter to represent a variable. The letters $x$, $y$, and $z$ are common generic symbols used for variables.
