4. Using the Math Input/Output Mode

Important!

• The fx-7400G

III is not equipped with a Math input/output mode.

Selecting “Math” for the “Input/Output” mode setting on the Setup screen (

page 1-31) turns on

the Math input/output mode, which allows natural input and display of certain functions, just as

they appear in your textbook.

• The operations in this section all are performed in the Math input/output mode.

- The initial default setting is the Math input/output mode. If you have changed to the Linear

input/output mode, switch back to the Math input/output mode before performing the

operations in this section. See “Using the Setup Screen” (

page 1-30) for information about

how to switch modes.

- Switch to the Math input/output mode before performing the operations in this section. See

“Using the Setup Screen” (page 1-30) for information about how to switch modes.

• In the Math input/output mode, all input is insert mode (not overwrite mode) input. Note that

the !D(INS) operation (page 1-6) you use in the Linear input/output mode to switch to

insert mode input performs a completely different function in the Math input/output mode. For

more information, see “Using Values and Expressions as Arguments” (page 1-16).

• Unless specifically stated otherwise, all operations in this section are performed in the

RUN • MAT mode.

fx-9750G

III users...

The fx-9750G

III “Input/Output” mode setting (page 1-31) has a “Mth/Mix” option that enables

the same input operation as when “Math” is selected. The only way “Mth/Mix” differs from

“Math” is that it outputs results of calculations including ' or π in decimal format.

For display examples of calculation results when “Mth/Mix” is selected, see “Example 4” (page

1-15) and “Math Input/Output Mode Input and Result Display in the EQUA Mode” (page 1-26).

u Math Input/Output Mode Functions and Symbols

The functions and symbols listed below can be used for natural input in the Math input/output

mode. The “Bytes” column shows the number of bytes of memory that are used up by input in

the Math input/output mode.
