Examples
Each section is followed by instructions for keystroke
examples that demonstrate the TI-36X Pro functions.
Examples assume all default settings, as shown in the Modes
section.
Some screen elements may differ from those shown in this
document.
Switching the calculator on and off
&turns on the calculator. % ' turns it off. The display
is cleared, but the history, settings, and memory are retained.
The APD™ (Automatic Power Down™) feature turns off the
calculator automatically if no key is pressed for about 5
minutes. Press &after APD. The display, pending
operations, settings, and memory are retained.
Display contrast
The brightness and contrast of the display can depend on
room lighting, battery freshness, and viewing angle.
To adjust the contrast:
1. Press and release the %key.
2. Press T(to darken the screen) or U(to lighten the
screen).
Home screen
On the Home screen, you can enter mathematical
expressions and functions, along with other instructions. The
answers are displayed on the Home screen. The TI-36X Pro
screen can display a maximum of four lines with a maximum
of 16 characters per line. For entries and expressions of more
than 16 characters, you can scroll left and right (!and ") to
view the entire entry or expression.
In the MathPrint™ mode, you can enter up to four levels of
consecutive nested functions and expressions, which include
fractions, square roots, exponents with ^, Ü, ex, and 10x.
4
When you calculate an entry on the Home screen, depending
upon space, the answer is displayed either directly to the right
of the entry or on the right side of the next line.
Special indicators and cursors may display on the screen to
provide additional information concerning functions or results.
Indicator Definition
2ND 2nd function.
FIX Fixed-decimal setting. (See Mode
section.)
SCI, ENG Scientific or engineering notation.
(See Mode section.)
DEG, RAD,
GRAD
Angle mode (degrees, radians, or
gradians). (See Mode section.)
L1, L2, L3 Displays above the lists in data
editor.
H, B, O Indicates HEX, BIN, or OCT
number-base mode. No indicator
displayed for default DEC mode.
The calculator is performing an
operation.
5 6 An entry is stored in memory before
and/or after the active screen. Press
#and $to scroll.
³´ An entry or menu displays beyond
16 digits. Press !or "to scroll.
Normal cursor. Shows where the
next item you type will appear.
Entry-limit cursor. No additional
characters can be entered.
Placeholder box for empty
MathPrint™ element. Use arrow
keys to move into the box.

2nd functions
%
Most keys can perform more than one function. The primary
function is indicated on the key and the secondary function is
displayed above it. Press %to activate the secondary
function of a given key. Notice that 2ND appears as an
indicator on the screen. To cancel it before entering data,
press % again. For example, %b25 < calculates
the square root of 25 and returns the result, 5.
Modes
q
Use qto choose modes. Press $ # ! " to choose a
mode, and < to select it. Press - or %s to
return to the Home screen and perform your work using the
chosen mode settings.
Default settings are highlighted in these sample screens.
DEG RAD GRAD Sets the angle mode to degrees,
radians, or gradians.
NORM SCI ENG Sets the numeric notation mode.
Numeric notation modes affect only the display of results, and
not the accuracy of the values stored in the unit, which remain
maximal.
NORM displays results with digits to the left and right of the
decimal, as in 123456.78.
MathPrint™ cursor. Continue
entering the current MathPrint™
element, or press an arrow key to
exit the element.
Indicator Definition
6
SCI expresses numbers with one digit to the left of the
decimal and the appropriate power of 10, as in
1.2345678E5 (which is the same as 1.2345678×105).
ENG displays results as a number from 1 to 999 times 10
to an integer power. The integer power is always a multiple
of 3.
Note: Eis a shortcut key to enter a number in scientific
notation format. The result displays in the numeric notation
format selected in the mode menu.
FLOAT 0 1 2 3 4 5 6 7 8 9 Sets the decimal notation mode.
FLOAT (floating decimal point) displays up to 10 digits,
plus the sign and decimal.
0 1 2 3 4 5 6 7 8 9 (fixed decimal point) specifies the
number of digits (0 through 9) to display to the right of the
decimal.
REAL a+bi r±q Sets the format of complex number
results.
REAL real results
a+bi rectangular results
r±q polar results
DEC HEX BIN OCT Sets the number base used for
calculations.
DEC decimal
HEX hexadecimal (To enter hex digits A through F, use
%§, %¨, and so on.)
BIN binary
OCT octal
CLASSIC MATHPRINT
CLASSIC mode displays inputs and outputs in a single
line.
MATHPRINT mode displays most inputs and outputs in
textbook format.

Multi-tap keys
A multi-tap key is one that cycles through multiple functions
when you press it.
For example, the Xkey contains the trigonometry functions
sin and sin/as well as the hyperbolic functions sinh and
sinh/. Press the key repeatedly to display the function that
you want to enter.
Multi-tap keys include z, X, Y, Z, C, D,
H, and g. Applicable sections of this guidebook describe
how to use the keys.
Menus
Menus give you access to a large number of calculator
functions. Some menu keys, such as %h, display a
single menu. Others, such as d, display multiple menus.
Press "and $ to scroll and select a menu item, or press
the corresponding number next to the item. To return to the
previous screen without selecting the item, press -. To
exit a menu and return to the Home screen, press %s.
%h(key with a single menu):
RECALL VAR (with values set to default of 0)
1: x = 0
2: y = 0
3: z = 0
4: t = 0
5: a = 0
6: b = 0
7: c = 0
8: d = 0

Scrolling expressions and history
!" # $
Press ! or "to move the cursor within an expression that
you are entering or editing. Press %!or % " to move
the cursor directly to the beginning or end of the expression.
After you evaluate an expression, the expression and its
result are added automatically to the history. Use #and $
to scroll through the history. You can reuse a previous entry
by pressing <to paste it on the bottom line, where you
can edit it and evaluate a new expression.

Answer toggle
r
Press the r key to toggle the display result (when
possible) between fraction and decimal answers, exact
square root and decimal, and exact pi and decimal.
Pressing rdisplays the last result in the full precision of its
stored value, which may not match the rounded value.
Example
Last answer
%i
The last entry performed on the home screen is stored to the
variable ans. This variable is retained in memory, even after
the calculator is turned off. To recall the value of ans:
•Press%i(ans displays on the screen), or
• Press any operations key (T, U, and so forth) as the first
part of an entry. ans and the operator are both displayed.
