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.
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 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 may display on the screen to provide additional information concerning functions or results. Indicator Definition 2ND 2nd function.
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.
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.

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.

Fractions P @ %O } %j In the MathPrint™ mode, fractions with P can include operation keys (T, V, etc.) and most function keys (F, _, etc.). In Classic mode, fractions with P do not allow operation keys, functions, or complex fractions in the numerator or denominator. Note: In Classic mode and Data editor, use W to perform complex division problems. Calculations using fractions can display fraction or decimal results, depending on input.
• %O converts between simplie fraction and mixed number form. • %j converts results between 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.

Powers, radicals, and reciprocals F Calculates the square of a value. The TI-34 MultiView™ calculator evaluates expressions entered with F from left to right in both Classic and MathPrint™ modes. Pressing 3 F F calculates as (32)2 = 81. G Raises a value to the power indicated. If you insert an expression as the exponent, you must place it between parentheses. 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.

Angle menu %= %= displays the choice of two submenus that enable you to specify the angle unit modifier as degrees (º), minutes ('), seconds ("), radian (r), or convert units using 4DMS. You can also convert between rectangular coordinate form (R) and polar coordinate form (P). Choose an angle mode from the mode screen. You can choose from DEG (default) or RAD. Entries are interpreted and results displayed according to the angle mode setting without needing to enter an angle unit modifier.

The order of objects is important, as in a race.
RAND contains the following options: rand Generates a random real number between 0 and 1. To control a sequence of random numbers, store an integer (seed value) | 0 to rand. The seed value changes randomly every time a random number is generated. randint( Generates a random integer between 2 integers, A and B, where A { randint { B. Separate the 2 integers with a comma.

ARGUMENT — A function does not have the correct number of arguments. DIVIDE BY 0 — You attempted to divide by 0. DOMAIN — You specified an argument to a function outside the valid range. For example: • For xÑy: x = 0 or (y < 0 and x is not an odd integer). • For Ñx: x < 0. • For LOG or LN: x { 0. • For tan: x = 90Ä, -90Ä, 270Ä, -270Ä, 450Ä, etc., and equivalent for radian mode. • For sin-1 or cos-1: |x| > 1. • For nCr or nPr: n or r are not integers | 0.
OP NOT DEFINED — Operation (op1 or op2) is not defined. MEMORY LIMIT — • The calculation contains too many pending operations (more than 23). • If using op1 or op2, you attempted to enter more than four levels of nested functions using fractions, square roots, exponents with ^, xÑ, and x2 (MathPrint™ mode only). LOW BATTERY — Replace the battery. Note: This message displays briefly and then disappears. Pressing - does not clear this message.
How to remove or replace the battery The TI-34 MultiView™ calculator uses one 3 volt CR2032 lithium battery. Remove the protective cover and turn the TI-34 MultiView calculator face downwards. • With a small screwdriver, remove the screws from the back of the case. • From the bottom, carefully separate the front from the back. Be careful not to damage any of the internal parts. • With a small screwdriver (if required), remove the battery.
