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.
