APD
é
(Automatic Power Down
é
) turns off the

ü
automatically if no key is pressed for about
five minutes. Press
T
after APD to power up again;
the display, pending operations, settings, and memory

Press
%
to activate the second function of a key. To
cancel the second function before making an entry,
press
%
again. In this manual, second functions are
shown in brackets ([ ]). For example, press

Display
The TI-36X
ü
has a two-line display. The first line
(Entry Line) displays an entry of up to 88 digits or
items (47 for Stat or Stored Operations). Entries begin
on the left; those with more than 11 digits scroll to the
left. You can have as many as 23 levels of parentheses
and up to 8 mathematical operations pending.
The second line (Result Line) displays a result of up to
10 digits, plus a decimal point, a negative sign, a x10
indicator, and a 2-digit positive or negative exponent.
Results that exceed the digit limit are displayed in
scientific notation.
Note: In the text, numbers containing decimal fractions
are shown in decimal format consistent with the
calculator display.
Scrolling
Scroll with
"
,
!
,
#
, and
$
.
•
Press
"
and
!
to scroll horizontally through the
current or previous entries, or to move the
underscore within a menu list. Press
%"
or
%!
to move the cursor to the beginning or end
of the entry.
•
After an expression is evaluated, press
#
and
$
to scroll through previous entries, which are stored
in the TI-36X
ü
history. If you edit a previous entry
and press
V
, the calculator will evaluate the
new expression and return the new result.

item. To select an underlined item:
•
Press
V
while the item is underlined. Or,
•
For menu items followed by an argument value,
enter the argument value while the item is
underlined. The item and the argument value are
transferred to the current entry. However, if the
argument is another function, you need to press
V
to select the first function before proceeding
to the next.
To return to the previous screen without selecting the
menu item, press
4
.
Fix
%t
displays a menu: F0123456789. To round
displayed results, scroll with
"
or
!
to select the
desired number of decimal places, or enter the numeral
corresponding to the desired number of decimal places.
The displayed value is padded with zeroes if needed.
To restore standard notation (floating decimal), select F
(default) in the menu, or press
%tI
.
You can specify rounding places before you begin your
calculations, before you complete an operation with
V
, or after the results are displayed.

Action depends on position of the cursor.
•
If cursor is in the middle of an entry,
clears character under the cursor and
all characters to the right of the
cursor.
•
If cursor is at the end of an entry,
clears the entire entry.
•
If an Error message is displayed,
clears the error message and moves
the cursor to last entry in history.
•
If a menu is displayed, exits menu.
'•
If the cursor is on a character, deletes
the character under the cursor.
•
If the cursor is at the end of an entry,
deletes the character to the left of the
cursor.
%[
Lets you insert one or more characters at
the cursor.
%s

Resets the TI-36X
ü
. Returns unit to
default settings; clears memory variables,
pending operations, all entries in history,
statistical data, Ans, and stored
operations. MEM CLEARED is displayed.
You can overwrite entries. Move the cursor to the
desired location and begin pressing keys. The new
keypresses will overwrite the existing entry, character
by character.
Before beginning a new set of examples or problems in
this manual, reset the calculator to ensure that your
displays will be the same as those shown.

Order of Operations
The TI-36X
ü
uses EOS
è
(Equation Operating
System) to evaluate expressions.
Order Evaluation

2nd Functions which need a ) and precede the
argument, such as sin, log, and all R
/
P
menu items; Boolean Logic NOT and 2’s
complement.
3rd Fractions.
4th Functions that are entered after the argument,
such as x
2
and angle unit modifiers (
é
ê
ë
r g
);
metric conversions.
5th Exponentiation (^) and roots (
