Something that is subject to variation the weather is one variable to be considered variable variable quantity noun a quantity that can assume any of a set of values. Variables are primarily represented in letters and do not have a fixed value attached to them. Varying in the context of mathematical variables does not mean change in the course of time but rather dependence on the context in which the variable is usedThis can be the immediate context of the expression in which the variable occurs as in the case of summation variables or variables that designate the argument of a function being defined.

Letters are used to represent these changing unknown quantities. An independent variable is a variable that isnt affected by something else. Variable Definition in Maths.

Part of the point of working with equations in math is to determine what the constraints are on your inputs and outputs. A variable in a logical or mathematical expression whose value determines the dependent variable. Determining or solving these constraints are.
