• Math Input/Output Mode Input and Result Display in the EQUA Mode
You can use the Math input/output mode in the EQUA mode for input and display as shown
below.
• In the case of simultaneous equations (1(SIML)) and high-order equations (2(POLY)),
solutions are output in natural display format (fractions, ', π are displayed in natural format)
whenever possible.
• In the case of Solver ( 3(SOLV)), you can use Math input/output mode natural input.
Example To solve the quadratic equation

5. Option (OPTN) Menu
The option menu gives you access to scientific functions and features that are not marked on
the calculator’s keyboard. The contents of the option menu differ according to the mode you
are in when you press the K key.
• The option menu does not appear if you press K while binary, octal, decimal, or
hexadecimal is set as the default number system.
• For details about the commands included on the option (OPTN) menu, see the “K key”
item in the “PRGM Mode Command List” (
page 8-41).
•
The meanings of the option menu items are described in the sections that cover each mode.
The following list shows the option menu that is displayed when the RUN • MAT (or RUN) or
PRGM mode is selected.
