A variable is a symbol or name that represents a value that can change or vary within a given context, often used in mathematical equations and programming. In contrast, a constant is a fixed value that does not change, remaining the same throughout the context in which it is used. Both concepts are fundamental in mathematics, science, and computer programming, allowing for the representation of dynamic and static quantities.
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 concept is an idea or an abstraction that stands for something. A concept becomes a variable when it is made operational or when it can be counted, categorized, or observed. For example, job satisfaction is a concept, but, it becomes a variable when a definition is it attached to it that makes it measurable. You may ask a married person, "how satisfied are you with your job?" If you attach levels of satisfaction to it, then it becomes a variable. All variables are concepts when you can measure the concept. However, not all concepts can be variables. A concept that is not a variable is a concept that is not measurable.
It is usually called the axis for the independent variable.
is the variable of x an example of abstract representation
An analog representation displays information in a continuous way, for example... the presentation of a wall clock shows the time in as a continuous variable, taking on any value within its constituent resolution. digital representation, also called discrete representation, displays information in terms of discrete, symbolic values, normally in terms of codes. In keeping with the same example, a digital representation would be a digital clock, whose representation of time is in terms of discrete variables (numbers)

A constant is a variable that is immutable. The storage representation is exactly the same as for any other variable of the same type, the only difference is that all constants are allocated in the program's data segment (static memory).
A term is a constant, a variable, or combination of constants and variables. Examples: 7.13, 5x, where 5 is the coefficient of the variable xy, xyz, y, where the coefficient of the variable is assumed to be 1.
