variable
In maths the symbols x and n are usually used to represent an unknown quantity. These may be referred to as a variable.
The letter symbol sometimes used to represent 'e' is the Greek letter epsilon (ε). In mathematics and various scientific fields, particularly in calculus and statistics, epsilon is often used to denote a small positive quantity or error margin.
Yes. Although it can also be used for constants whose value is not yet known.
No, there is not.

Variable
The letter or symbol used to represent an unknown quantity 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.
The triangle symbol that means change is called the delta symbol. It is commonly used in mathematics and science to represent a change in quantity or variable.
x or any other variable
A letter or symbol used to represent an unknown quantity is called a "variable." In mathematics, variables are often represented by letters such as x, y, or z and are used in equations and expressions to denote values that can change or vary. They play a crucial role in algebra and other branches of mathematics, allowing for generalization and abstraction in problem-solving.

An elipsis or * * * is used to present a change of scene.
In mathematics, a symbol that represents an unknown quantity is typically denoted by a variable, such as "x" or "y". These variables are used to represent values that are not yet known or are subject to change. They are commonly used in algebraic equations to solve for the unknown quantity based on given information or conditions.
