About this User's Guide
Model-specific Function and Screen Differences
This User's Guide covers multiple different calculator models. Note that some of the functions
described here may not be available on all of the models covered by this User's Guide. All of
the screen shots in this User's Guide show the fx-9860G SD screen, and the appearance of
the screens of other models may be slightly different.
Math natural input and display
Under its initial default settings, the fx-9860G SD, fx-9860G , or fx-9860G AU PLUS
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, differentials, 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 initial default setting of the fx-9860G SD, fx-
9860G , and fx-9860G AU PLUS input/output mode is the Math input/output mode.
The examples shown in this User's Guide are mainly presented using the Linear input/output
mode. Note the following points if you are using an fx-9860G SD, fx-9860G , or fx-9860G
AU PLUS.
• 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 1-26).
• For information about input and display using the Math input/output mode, see "Using the
Math Input/Output Mode" (page 1-10).
For owners of models not equipped with a Math input/output mode
(fx-7400G , fx-9750G )...
The fx-7400G and fx-9750G do not include a Math input/output mode. When performing
the calculations in this manual on these models, use the linear input mode.
fx-7400G and fx-9750G owners should ignore all explanations in this manual concerned
with the Math input/output mode.
