4. Using the Math Input/Output Mode
Selecting “Math” for the “Input/Output” mode setting on the Setup screen (page 1-32) 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 for this calculator 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 1-32) 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 1-7) 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 1-17).
• Unless specifically stated otherwise, all operations in this section are performed in the
Run-Matrix mode.

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.
