A variable changes. It varies.
A non variable does not change. It is constant.
For example if I write a mathematical expression such as x + 1, then x is a variable. Its value can be whatever value we choose. However 1 is a non variable. Its value is 1 and never changes from 1.
In a scientific experiment a variable would be something that you changed from one test to another. A non variable would be something that remained constant from test to test.
As a final example: the speed at which light travels in a vaccum is a constant. It is referred to by the letter c which stands for the universal constant. However, the speed at which your car travels is a variable. It changes.

Difference between variable resistor and rheostat?
The difference between a variable resistor and a rheostat is the same as the difference between six and half a dozen.
What the difference between a variable and control?
The difference between a controlled variable and a variable is in their state. A controlled variable is something which is rigid and constant while a variable is liable to change and inconsistent.
WAP to show the difference between a variable and static variable?
difference between constant and static variables in java
What is the difference between a variable being tested and a variable being controlled?
The difference between these both is that the control is what stays the same in an experiment and the variable is what changes.
What is one difference between a variable and a numerical expression?
The variable.

What is the difference between a variable and a rule?
a variable changes a rule doesn't.
What is one difference between a variable expression and a numerical expression?
The variable.
How can you identify a linear nonproportional relationship from a table a graph and an equation?
Table The difference in the values of the "dependent" variable is a fixed multiple of the difference between the corresponding values of the independent variable. And the value of the dependent variable is non-zero when the independent is zero.Graph A non-vertical straight line which does not pass through the origin.Equation y = mx + c (or equivalent) where m is some real number and c is non-zero.
