### What is Meant by the Variable?

In mathematics, a variable is defined as a quantity that might change according to the context of the mathematical problem. Generally, a single letter is used as a variable most commonly, and the letters used are x, y and z in many mathematical problems. In algebraic equations, the value of one variable is dependent on another variable. Hence, variables are classified into two types, namely the dependent variable and independent variable.

For example, x+y = 5

If x = 2, then y = 5-3 = 3

In this case, x is called the independent variable and y is called the dependent variable
