The
fx-991EX
“ClassWiz” features a high-resolution
display, making it easier to view formulas and symbols.
This remarkable screen can display between 2-6 times
as many characters as other scientific calculators, yet
still runs on solar power.
Use the
W
key to turn the calculator on, and press
qC
(OFF)
to power the unit down.
The icon-based menu, accessible via the
p
key,
allows easy navigation of features using the arrow keys
and the number keys or the
Q
shortcuts.
The
o
key can be used like Backspace in a word
processor to delete the character(s) left of the cursor.
The symbols printed on the keys use Natural Textbook
Display™ notation, similar to that found in textbooks.
This makes input of expressions fast and easy.
The
n
key toggles your calculation results between
Standard (exact) and Decimal forms.
