They are used to represent known and unknown values in equations. Usually x, y, and z are unknown; and a, b, and c are known. But u can use anything to represent anything! It helps to solve for unknowns that you need to figure out!

In maths the symbols x and n are usually used to represent an unknown quantity. These may be referred to as a variable.
Nothing specifically is "done" to the variable; variables are generally used to represent either:* A quantity that is initially unknown (and should be solved for), or * A quantity that can be anything - to analyze what happens no matter what a certain value is.
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.
A variable is any factor, trait, or condition that can exist in differing amounts or types. An experiment usually has three kinds of variables: independent, dependent, and controlled.
Yes. Although it can also be used for constants whose value is not yet known.
The variable "I" in algebra can represent any unknown quantity or value. It is commonly used to represent interest in mathematical equations related to finance or economics. However, "I" can refer to any unknown in an equation and its meaning depends on the specific context in which it is used.
