Conventions Used in This Guide
This guide references various functions of the calculator in the following manner:
The keys on the calculator are divided into two sections for easier accessibility.
The top part of the calculator is referred to as the Orion, and the bottom part is
referred to as the TI-84 Plus.
When referencing the location of a TI-84 Plus key, the rows begin at the
bottom and the columns begin on the left. For example, the
On
key is located at
the bottom left of the TI-84 Plus in column 1, row 1.
The location of certain keys on the Orion section of the unit is described as
follows:
o
The six keys on the left side are referenced as top, middle, bottom, and
left, right. For example, the
Preference
key (
Pref.
) is the top-right key.
o
The five keys on the right side are referenced as up, down, left, right, and
home.
o
Both sets of keys can be used in conjunction for navigation and other
functions. For example, pressing both the
CTRL
key, which is the
bottom-left key on the left side of the Orion, and the
Left Arrow
key,
which is located on the right side of the Orion, lets you navigate to the
far left of the review line.
The following example demonstrates how to calculate the square root of 9 using the
keys on the TI-84 Plus section of the calculator:

4.
Press the

The TI-84 Plus announces the answer. If you wish to repeat the answer, press
the

above the key). Repeat is the top-left key in the left set of keys of the Orion.
