in algebra any letter really, however normally it's an x
A variable
Variable.
Six less an unknown number can be expressed mathematically as ( 6 - x ), where ( x ) represents the unknown number. This expression indicates that you subtract the value of the unknown number from six. The result will vary depending on the specific value of ( x ).
x is a variable that represents an unknown number and its value depends on the algebraic expression it is used in.
The letter that commonly represents an unknown in mathematics is "x." It is frequently used in algebraic equations to denote a variable or an unknown value that needs to be solved for. Other letters like "y" and "z" are also used, but "x" is the most widely recognized.
In mathematical expressions, a variable (a letter used to represent a certain value) represents an unknown or changeable value. It is often the variable x.

It is unknown and it usually just represented as pi. It represents the ratio between the circumference and the diameter.
An unknown in an algebraic expression is a variable that represents a value we do not yet know. It is typically denoted by letters such as (x), (y), or (z). The purpose of the unknown is to allow for the formulation of equations and the exploration of relationships between quantities. Solving the expression involves finding the value of the unknown that satisfies the equation.
x= the unknown
In mathematics, a variable is a representation, in the form of a letter, of a numerical value. Variables are traditionally used when the value it represents is either unknown or can vary.
A variable is usually used for that - for example, a single letter that represents the unknown quantity.
