Using Variable Names
Variables and Defined Items
You can enter and use several types of data, including real and complex
numbers, matrices, lists, functions, stat plots, graph databases, graph
pictures, and strings.
The TI-84 Plus C uses assigned names for variables and other items saved
in memory
. For
lists, you also can create your own five-character names.
Notes about Variables
• You can create as many list names as memory will allow (Chapter 11
in the guidebook).
• Programs have user-defined names and share memory with variables
(Chapter 16 in the guidebook).
