Examples

Each section is follow ed by instructions for keystroke examples that demonstrate the TI-30XS MultiView™ and TI-30XB MultiView functions. All references in this manual will refer to the TI-30XS MultiView, but are also applicable for the TI-30XB MultiView.

Examples assume all default settings, as shown in the Modes section.

For more activities and examples, see the TI-30XS MultiView™ Teacher Guide available at education.ti.com/

guides.

Switching the

TI-30XS MultiView

calculator on

and off

& turns on the TI-30XS MultiView calculator. % ' turns it off. The display is cleared, but the history, set tings , and memory are retained.

The APD™ (Automatic Power Down™) feature turns off the TI-30XS 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-30XS 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.

In the MathPrint™ mode, you can enter up to four levels of consecutive nested functions and expressions, which include fractions, square roots, exponents with ^, Ê, e

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.

¹ ¸ An entry or menu displays beyond

16 digits. Press ! or " to scroll.

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, % b 25 < calculates the square root of 25 and returns the result, 5.

Modes

Use pto choose modes. Press $ # ! " to choose a mode, and < to select it. Press - or %Q to return to the Home screen and perform your work using the chosen mode settings.

Default mode settings are shown highlighted.

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.

SCI expresses numbers with one digit to the left of the decimal and the appropriate power of 10, as in

1.2345678Ã10

(which is the same as 123456.78).

Note: In some restricted environments (for example function table, data editor, and the %h menu), the TI-30XS MultiView™ calculator may display E instead of

Ã10

ENG displays results as a number from 1 to 999 times 10 to an integer power. The in teger power is alw ays a multiple of 3.

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.

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. MATHPRINT mode displays most inputs and output s in

textbook format.

Menus

Certain keys display menus: H, % I, v, %t, %, %h, and %{. Some

keys may display more than one menu. Press " and $ to scroll and select a menu item, or press

the corresponding number next to the menu item. To return to the previous screen without selecting the item, press -. To exit a menu or application and return to the Home screen, press %Q.

The menu chart shows the menu keys and the menus they display.

Scrolling

! " # $ Press ! or " to place the cursor horizontally over the

expression entered. Press % ! or % " to move the cursor directly to the beginning or end of the expression.

After an expression is evaluated, use # and $ to scroll through previous entries, which are stored in the TI-30XS MultiView™ calculator’s memory. You can reuse a previous entry by pressing < to paste it on the bottom line, and then evaluating a new expression.

Examples

Scroll 1 T 1 <

% b 8 <

Last answer

% i

The most recently calculated result is stored to the variable Ans. Ans is retained in memory, even after the TI-30XS MultiView™ 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.

Examples

Order of operations

The TI-30XS MultiView™ calculator uses Equatio n Ope rating 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

and angle unit modifiers.

5th

Exponentiation (^) and roots (

Note: In Classic mode, exponentiation 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 is

evaluated from right to left. The expression

2^3^2 is evaluated as 2^(3^2), with a result of

512.

J Deletes the character at the cursor. % f Inserts a character at the cursor. % { Clears variables x, y, z, t, a, b, and c. %  2

or & & -

Clears characters on entry line. Moves the cursor to last entry in history once display is clear. Backs up one screen in applications.

Resets the TI-30XS MultiView™ calculator. Returns unit to default settings; clears memory variables, pending operations, all entries in history , and statistical data; clears the constant feature, K, and Ans.

Fractions

q%N% j% O

In the MathPrint™ mode, fractions with q can include operation keys (T, V, etc.) and most function keys (F, %_, etc.).

In Classic mode, fractions with q do not allow operation keys, functions, or complex fractions in the numerat or or denominator.

Note: In Classic mode, data editor, and table, use W to perform complex division problems.

Calculations using fractions can display fraction or decimal results, depending on input.

The TI-30XS MultiView™ calculator defaults output to improper fractions. Results are automatically simplified.

• q enters a simple fraction. Pressing q before or after a number can result in different behavior. Entering a number before pressing q makes that number the numerator.

To enter fractions with operators or radicals, press q before 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 q between the entry of the numerator and the denominator.

• %N enters a mixed number. Press %N between the entry of the unit and the numerator.

• % O converts between mixed numbers and simple fraction form.

• % j converts results between fractions and decimals.
