Creating TI-Nspire™ Variables
Variables can be any portion or attribute of an object or function created
within an application. Examples of attributes that can become variables
are the area of a rectangle, the radius of a circle, the value contained in a
spreadsheet cell or the contents of a column, or a function expression.
When you create a variable, it is stored in memory within the problem.
You will find more information about variables in the chapter titled
Using Variables.
