**What does x mean in math:**

What does x mean in math? An explanation of mathematical variables and an introduction to the algebraic concept.

A variable is a symbol (x or y) representing one or more values in mathematics, which can change or vary. A letter representing a value is called an unknown. For example, in the equation 2 + 3 = 5, the letters ‘a’ and ‘b’ represent numbers; they are called “variables”. The letter ‘x’ is often used to represent an unknown number in many equations.

However, its usage might depend on the context of the problem it’s being used for. Variables are usually lowercase Greek letters in geometry problems involving lengths that are not specified. In a situation involving a right triangle with legs ‘a’ and ‘b,’ the hypotenuse would have length c, represented by the lowercase Greek letter delta.

**What does x mean in numbers:**

What does x mean in numbers? This is a mathematical symbol that stands for an unknown number. In solving equations, this symbol represents the variable’s value being solved. For instance, if you are solving for x in the equation 2x + 5 = 15, then x equals 10.
