Selecting Icons
This section describes how to select an icon in the Main Menu to enter the mode
you want.
STo select an icon
1. Press Kto display the Main Menu.
2. Use the cursor keys (B,C,D,A)to
move the highlighting to the icon you want.
3. Press Uto display the initial screen of the
mode whose icon you selected. Here we will
enter the STAT mode.
• You can also enter a mode without highlighting an icon in the Main Menu by
inputting the number or letter marked in the lower right corner of the icon.
• Use only the procedures described above to enter a mode. If you use any other
procedure, you may end up in a mode that is different than the one you thought
you selected.
The following explains the meaning of each icon.
Icon Mode Name Description
RUN • MAT
(Run • Matrix)
Use this mode for arithmetic calculations and function
calculations, and for calculations involving binary, octal,
decimal, and hexadecimal values and matrices.
STAT
(Statistics)
Use this mode to perform single-variable (standard
deviation) and paired-variable (regression) statistical
calculations, to perform tests, to analyze data and to
draw statistical graphs.
e • ACT
(eActivity)
eActivity lets you input text, math expressions, and other
data in a notebook-like interface. Use this mode when
you want to store text or formulas, or built-in application
data in a file.
S • SHT
(Spreadsheet)
Use this mode to perform spreadsheet calculations.
Each file contains a 26-column × 999-line spreadsheet.
In addition to the calculator’s built-in commands and
S•SHTmode commands, you can also perform
statistical calculations and graph statistical data using the
same procedures that you use in the STAT mode.
