Each section is followed by instructions for keystroke
examples that demonstrate the TI-34 MultiView™ functions.

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.

4
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 x2.
When you calculatean entry on the Home screen, depending
uponspace,theanswerisdisplayedeither directlytotheright
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.
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 <calculatesthe 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.
NORMdisplaysresultswithdigitstotheleftandrightofthe
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
1.2345678x105(which is the same as 123456.78).
Note: C isa shortcutkeyto enter a numberinscientific

Note: In some restricted environments (for example, data
editor and the %h menu), the TI-34 MultiView™
calculator may display Einstead of x10n.
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.

6
MATHPRINT mode displays most inputs and outputs 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-by-
step. »next to the resulting fraction signifies thatthe
fraction is not yet in simplest form. See Fractions, }
for details.
AUTOSIMP The calculator automatically simplifies
fractional results to the lowest terms.

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.

Examples
5th Exponentiation (^) and roots (xÑ).
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

Fractions
P@ %O } %j
In the MathPrint™ mode, fractions with Pcan include
operationkeys(T,V,etc.)andmostfunctionkeys(F,_,
etc.).
In Classic mode, fractions with Pdo not allow operation
keys, functions, or complex fractions in the numerator or
denominator.
Note: In Classic mode and Data editor, use Wto perform
complex division problems.
Calculations using fractions candisplay fraction ordecimal
results, depending on input.
•Penters a simple fraction. Pressing Pbefore or after a
number can result in different behavior. Entering a number
before pressing Pmakes that number the numerator.
To enter fractions with operators,press Pbefore you
enter a number (in MathPrint mode only).
In MathPrint mode, press $between the entry of the
numerator and the denominator.
In Classic mode, press Pbetween the entry of the
numerator and the denominator.
•@enters a mixed number. Press @between the entry
of the unit and the numerator, and press $between the
entry of the numerator and the denominator.
•}n < simplifiesa fractionby thefactornspecified
The entry nmust be a positive integer.
•} < automatically simplifies a fraction using the
lowest common prime factor. The factor displays.
Repeatedlypress} < tosimplify thefractionto its
lowest terms.
%i %Y 60 <

•%O converts between simplie fraction and mixed
number form.
•%j converts resultsbetween fractions and
decimals.
From q, you can select
•ManSimp (default) The user simplifies fractions manually
step-by-step. »next to the resulting fraction signifies that
the fraction is not yet in simplest form.
•AutoSimp The calculator automatically simplifies
fractional results to the lowest terms.
