Examples

Each section is followed by instructions for keystroke examplesthat demonstrate the TI-30XPlus MultiView™ functions.

Examplesassume all default settings, as shown in the Modes section.

Some screen elements may differ from those shown in thisdocument.

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 automaticallyif 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 U (to darken the screen) or U (to lighten the screen).

Home screen

On the Home screen, you can enter mathematical expressionsand functions, along with other instructions. T he answers are displayed on the Home screen. The TI-30XPlusMultiView™ screen can display a maximum of four lineswith a maximum of 16 characters per line.For entries and expressions of more than 16 characters, you can scrollleft and right (! and ") to view the entire entry or expression.

In the MathPrint™ mode, you can enter up to four levels of consecutive nested functionsand expressions, which include fractions,square roots, exponents with ^, Ü, ex, and 10x.

When you calculate an entry on the Home screen, depending upon space, the answer is displayed either directlyto the right of the entry or on the right side of the next line.

Specialindicators and cursors may displayon the screen to provide additional information concerning functionsor results.

2nd functions

Most keys can perform more than one function. The primary function isindicated on the key and the secondary functionis displayedabove it. Press % to activate the secondary function of a given key. Notice that 2N D appears as an indicator on the screen. To cancelit before entering data, press % again. For example, % b 25 < calculatesthe square root of 25 and returns the result, 5.

Modes

Use q to choose modes. Press $ # ! " to choose a mode, and < to select it. Press - or

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.

NOR M SCI ENG Sets the numeric notation mode.

Numericnotation modes affect only the display of results, and not the accuracy of the valuesstored in the unit, which remain maximal.

NOR M displays resultswith 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 1.2345678×5 (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 isalways a multiple of 3.

Order of operations

The TI-30XPlusMultiView™ calculator uses Equation Operating System (EOS™) to evaluate expressions. Withina prioritylevel, EOS evaluates functionsfrom left to right and in the following order.

1st Expressionsinside parentheses.

2nd Functions that need a ) and precede

the argument, such as sin, log, and all

R³´P menu items.

3rd Fractions.

4th

Functions that are entered after the argument, such as x2and angle unit modifiers.

5th Exponentiation (^) and roots (x‡).

Note: In Classicmode, exponentiation

using the G key 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 the G key is evaluated from right to left. The expression 2^3^2 is evaluated as 2^(3^2), with a result of

512.

Fractions

P % @ d 1 % ã f³´dä In the MathPrint™ mode, fractions with P can include

real and complex numbers, 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 fractionsin the numerator or denominator.

Note:In Classicmode, only number entriesare

supported when using P. Fractions in Classicmode are shown with a double-thick fractionbar (for example, ). The numerator must be an integer, and the denominator must be a positiveinteger. To compute more complexexpressions(functions, variables,complex numbers, etc.), use W along with ( and ).

The calculator defaults output to improper fractions. Results are automatically simplified.

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

To enter fractionswith operators or radicals, press P 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 P between the entry of the numerator and the denominator. The fraction bar will appear thicker than the division bar.

• Pressing % # from any MathPrint™ level, including the denominator or a lower limit, places the cursor in the history. Pressing enter will then paste the expression back to that MathPrint™ level.

- To paste a previous entry in the

denominator, place the cursor in the denominator, press % # to scroll to the desired entry, and then press < to paste the entry to the denominator.

- To paste a previous entry in the numerator

or unit, place the cursor in the numerator or unit, press # or % # to scroll to the desired entry, and then press < to paste the entry to the numerator or unit.

• % @ enters a mixed number. Pressthe arrow keysto cycle through the unit, numerator, and denominator.

• d 1 converts between simplefractions and mixed-number form (4n/d³´Un/d).

• % ã f³ò´dä converts resultsbetween fractions and decimals.

If you perform any regression calculation, the regression calculation and the 2-Var statisticsfor that data are stored in the StatVars menu until the next statistics or regression calculation. The results must be interpreted based on which type of statisticsor regression calculation was last performed.

Errors

When the calculator detectsan error, it returns an error message with the type of error. The followinglist includes some of the errors that you may encounter.

To correct the error, note the error type and determine the cause of the error. If you cannot recognize the error, refer to the following list.

Press - to clear the error message. The previous screen isdisplayed with the cursor at or near the error location. Correct the expression.

The following list includes some of the errors that you may encounter.

0<ar ea<1 — This error is returned when you input an

ARGUMENT — This error is returned if:

• a function does not have the correct number of arguments.

• the lower limit is greater than the upper limit.

• either index value is complex.

BREAK — You pressed the & key to stop evaluation of

an expression.

• You attempted to execute a complex number in an area that is not allowed.

DIM MISMATC H — You get this error if

• you attempt to store a data type with a dimension not allowed in the storing data type.

DIVIDE BY 0 — This error is returned when:

• you attempt to divide by 0.

• in statistics,n= 1.
