If it does not change it isn't variable. The converse is also true.
It is the rate of change of a variable.
It is the rate of change of one variable with regard to another.

its a variable
There is no such thing as definite variable in mathematics. Some of the variables in mathematics are independent and dependent variables. More variables are usually found in probability textbooks.
A variable does not usually "cause" another. A change in one variable may result in a change in another. Such a change may be systematic (the relationship between the two variables is precise) or it may be statistical or correlational. The reasons for either type will often depend on disciplines of knowledge other than mathematics, such as physics or economics etc.
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 in Mathematics is defined as the alphabetic character that expresses a numerical value
No, as the name Variable implies, it can and does change. Since it is 'Independent' its change is not a direct effect of the change of any other Variable. Additionally, the independent variable depends on the dependent variable.
The independent variable is the variable that you change and manipulate in an equation. This causes the dependant variable to change.
It is the kind of variable that you purposely change.
The variable that changes due to a change in another variable is known as 'dependant variable".
