Examples
Each section is followed by instructions for keystroke
examples that demonstrate the TI-34 MultiView™ functions.
Examples assume all default settings, as shown in the Modes
section.
For more activities and examples, see the TI-34 MultiView
Teacher Guide available at education.ti.com/guides.
Switching the TI-34 MultiView calculator on
and off
& turns on the TI-34 MultiView 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
TI-34 MultiView 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-34
MultiView 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.
3
In the MathPrint™ mode, you can enter up to four levels of
consecutive nested functions and expressions, which include
fractions, square roots, exponents with ^, xÑ, and x
2
.
When you calculate an entry on the Home screen, d epen ding
upon space, the answer is displayed either d irectly to the right
of the entry or on the right side of the next line.
Special indicators 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 Scientific notation. (See Mode section.)
DEG, RAD Angle mode (degrees or radians). (See Mode
section.)
L1, L2, L3 Displays above the lists in Data Editor.
The TI-34 MultiView™ calculator is performing
an operation.
º » An entry is stored in memory before and/or after
the active screen. Press # and $ to scroll.
¸ ¹ An entry or menu displays beyond 16 digits.
Press ! and " to scroll. (See Scrolling on
page 10 for more information.)
2nd functions
%
Most keys can perform two functions. 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, 3 %c 125 < calculates the cube root of
125 and returns the result, 5.

Modes
q
Use q to 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 shown.
DEG RAD Sets the angle mode to degrees or radians.
NORM SCI 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.
SCI expresses numbers with one digit to the left of the
decimal and the appropriate power of 10, as in
1.2345678x10
Note: C is a shortcut key to enter a number in scien tific
notation format. The result displays in the numeric notation
format set in mode.
Note: In some restricted environments (for example, data
editor and the %h menu), the TI-34 MultiView™
calculator may display
FLOAT 0123456789 Sets the decimal notation mode.
FLOAT (floating decimal point) displays up to 10 digits,
plus the sign and decimal.
0123456789 (fixed decimal point) specifies the number of
digits (0 through 9) to display to the right of the decimal.
CLASSIC MATHPRINT
CLASSIC mode displays inputs and outputs in a single
line.
5
(which is the same as 123456.78).
E instead of x10
n
.
5
MATHPRINT mode displays most inputs and output s in
textbook format. Choose the MathPrint™ mode for better
visual confirmation that math expressions have been
entered correctly and to better reinforce the correct math
notation.
Note: Switching the mode between Classic and MathPrint
clears calculator history and the stored operations (op1 or
op2) value.
Un/d n/d Determines how fractional results are displayed.
Un/d displays results as a mixed number, if applicable. n/d
displays results as a simple fraction.
MANSIMP AUTOSIMP Determine whether or not a
fractional result will be simplified automatically.
MANSIMP The user simplifies fractions manually step-bystep. » next to the resulting fraction signifies that the
fraction is not yet in simplest for m . See Fractions, }
for details.
AUTOSIMP The calculator automatically sim pl ifies
fractional results to the lowest terms.

! " # $
Press ! or " to scroll entries on the Home screen and to
navigate in menus. Press %! or %" to move the
cursor directly to the beginning or end of the current
expression.
# and $ moves the cursor up and down through menu
items, entries in Data editor, and previous entries on the
Home screen. Y ou can reuse a previous entry by pressing
< to paste it on the bottom line, and then evaluating a new
expression.
%# moves the cursor to the top entry of the active column
in Data editor, or to the previous entry on the Home screen.
Press %# again to move the cursor to the oldest entry on
the Home screen.
%$ moves the cursor to the first blank row of the active
column in Data editor, or below the last entry on the Home
screen.

The most recently calculated result is stored to the variable
ans. ans is retained in memory, even after the TI-34
MultiView™ calculator is turned off. To recall the value of ans:

Order of operations
The TI-34 MultiView™ calculator uses Equation Operating
System (EOS™) to evaluate expressions. Within a priority
level, EOS evaluates functions from left to right and in the
following order.
1st Expressions inside parentheses.
2nd Functions that need a ) and precede the argument,
such as sin, log, and all R ¶P menu items.
3rd Fractions.
4th Functions that are entered after the argument,
such as x
2
and angle unit modifiers.
12
5th
Exponentiation (^) and roots (
x
Ñ).
Note: In Classic mode, exponentiation using G is
evaluated from left to right. The expression 2^3^2
is evaluated as (2^3)^2, with a result of 64.
In MathPrint™ mode, exponentiation using G is
evaluated from right to left. The expression 2^3^2
is evaluated as 2^(3^2), with a result of 512.
The TI-34 MultiView™ calculator evaluates
expressions entered with F from left to right in
both Classic and MathPrint modes.
6th
Negation (
M).
7th Permutations (nPr) and comb in ations (nCr).
8th Multiplication, implied multiplication, division.
9th Addition and subtraction.
10th Conversions (n/d ¶U n/d, f¶d, ´DMS).
11th < completes all operations an d clos es all open
parentheses.

Clearing and correcting
- Clears characters and error messages.
J Deletes the character at the cursor.
%f Inserts a character at the cursor.
%{ Clears variables x, y, z, t, a, b and c.

Clears characters on the entry line, then
clears the display when you press again. Scroll up to clear entries in history.
Backs up one screen in applications.
Returns unit to default settings; clears
memory variables, pending operations,
all entries in history, function s in
applications, and statistical data; clears
stored operations (op1 or op2), and ans.
Math operations
d
d displays a menu with two submenus. Some functions
require you to enter 2 values, numbers, or expressions that
equal or return a number. %` separates two values.
