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.
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).
