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, ex, and 10x.

When you calculatean entry on the Home screen, depending

uponspace,theansweris displayed either 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.

and/or afterthe active screen. Press

#and $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, %b25 < 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 ENGSetsthenumericnotationmode.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

1.2345678Ã105(which is the same as 123456.78).

¹ ¸ An entry or menu displays beyond

16 digits. Press !or "to scroll.

Note: In some restricted environments (for example

function table, data editor, and the %h menu), the

TI-30XS MultiView™ calculator may display Einstead of
