k About this User’s Guide

u Attention fx-CG10, fx-CG20, fx-CG20 AU Users

This manual explains how to use the fx-CG50. There are some differences in the marking of

some fx-CG50 keys and the keys of the fx-CG10, fx-CG20, and fx-CG20 AU. The table below

shows the differences in key markings.

fx-CG50 fx-CG10/fx-CG20/fx-CG20 AU

f M

u Math natural input and display

Under its initial default settings, the calculator is set up to use the “Math input/output mode”,

which enables natural input and display of math expressions. This means you can input

fractions, square roots, derivatives, and other expressions just as they are written. In the

“Math input/output mode”, most calculation results also are displayed using natural display.

You also can select a “Linear input/output mode” if you like, for input and display of

calculation expressions in a single line.

The examples shown in this User’s Guide are mainly presented using the Math input/output

mode. “<Linear input/output mode>” will be indicated for examples that use the Linear input/

output mode.

• For information about switching between the Math input/output mode and Linear input/

output mode, see the explanation of the “Input/Output” mode setting under “Using the Setup

Screen” (

page 1-35).

• For information about input and display using the Math input/output mode, see “Using the

Math Input/Output Mode” (

page 1-15).

u !x(')

The above indicates you should press ! and then x, which will input a ' symbol. All

multiple-key input operations are indicated like this. Key cap markings are shown, followed by

the input character or command in parentheses.

u m Equation

This indicates you should first press m, use the cursor keys (f, c, d, e) to select

the Equation mode, and then press w. Operations you need to perform to enter a mode

from the Main Menu are indicated like this.

u Function Keys and Menus

• Many of the operations performed by this calculator can be executed by pressing function

keys 1 through 6. The operation assigned to each function key changes according to

the mode the calculator is in, and current operation assignments are indicated by function

menus that appear at the bottom of the display.
