Calculator; Getting Started With The Calculator Application - Texas Instruments TINSPIRE Manual Book

Calculator

Getting started with the Calculator application

The Calculator application gives you a place to enter and evaluate math
expressions. You can also use it to define variables, functions, and
programs. When you define or edit a variable, function, or program, it
becomes available to any TI-Nspire™ math and science learning
technology application—such as Graphs & Geometry—that resides in the
same problem.
You can also use Calculator to define library objects, such as variables,
functions, and programs, which are accessible from any problem of any
document. For information on creating library objects, see the
"Libraries" section of the documentation.
