Deferring evaluation

You don't have to complete and evaluate an expression as soon as you
begin typing it. You can type part of an expression, leave to check some
work you did on another page, and then come back to complete the
expression later.

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™ math and science
learning technology 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.
Exception: Variables created with the
defined function or program are not accessible outside that function or
program.
