Calculator Operations with the Orion TI-84 Plus

The only difference between the Orion TI-84 Plus operations and the TI-84 Plus
operations is that the Orion announces or creates audible representations of the
output. Other than that, all other Orion T1-84 Plus operations are exactly the
same as the TI-84 Plus.
The following section is an overview of how the accessible features of the Orion
TI-84 work. For additional information about the operations of the TI-84 Plus,
please see the accessible versions of the TI-84 Plus Guidebook found at the
Orion TI-84 Plus Resources page
Guidebook.
7.1 Home Screen Operations
After turning on the calculator, you can go to the Home screen operations by
pressing the Clear key (column 5, row 7) twice; or by pressing the 2nd key and
then the Quit Mode key (column 2, row 9) on the calculator.
The Home screen is the primary screen of the TI-84 Plus. This is where you
enter instructions to execute or expressions to evaluate. The answers are
displayed on the Home screen in a list of 16 lines called the history. Most
calculations and answers are stored in the history on the Home screen. Use the
Up or Down key to scroll through the history of entries on the Home screen.
For additional information about the Home screen not covered in this guide,
