Working with Variables
When you first store a value in a variable, you give the variable a name.
• If the variable does not already exist, Calculator creates it.
• If the variable already exists, Calculator updates it.
Variables within a problem are shared by TI-Nspire™ applications. For example, you
can create a variable in Calculator and then use or modify it in Graphs&Geometry or
Lists&Spreadsheet within the same problem.
For more information, see Using Variables.
