General Information

Examples: watch the last web page of these instructions because that keystroke instances that demonstrate many of the TI-30X Ö functions. Examples assume every default settings.

& turns top top the TI-30X Ö. % ‘ turns that off and clears the display.

APD™ (Automatic power Down™) transforms off the TI-30X Ö automatically if no vital is pressed for about 5 minutes. Press & after APD. The display, pending operations, settings, and also memory are retained.

2-Line Display: The an initial line (Entry Line) screens an entrance of approximately 88 number (or 47 digits for Stat or continuous Entry Line). Entries start on the left; those with an ext than 11 digits scroll to the right. Press ! and “ to scroll the line. Press % ! or % “ to relocate the cursor instantly to the beginning or finish of the entry.

The second line (Result Line) displays a an outcome of up to 10 digits, add to a decimal point, a negative sign, a “x10” indicator, and a 2-digit hopeful or negative exponent. Results that exceed the digit border are presented in clinical Notation.




2nd function.


Hyperbolic function.


Fixed-decimal setting.


Scientific or design Notation.


Statistical mode.



Angle setting (degrees, radians, or gradients).


Constant mode is on.


Precedes the exponent in clinical or engineering Notation.

º »

An entrance is save in memory before and/or ~ the energetic screen. Press # and $ to scroll.

¹ ¸

An entrance or menu displays beyond 11 digits. Press ! or “ to scroll.

2nd Functions: % displays the 2nd indicator, and also then selects the second function (printed above keys) of the next crucial pressed. For example, % b 25 E calculates the square root of 25 and returns the result, 5.

Menus: certain TI-30X Ö keys display screen menus: z,

% h, L, % t, u, % w,

H, I, =, % k, % d, % ‚, and

% .

Press ! or “ to relocate the cursor and underline a menu

item. To return to the previous display screen without choosing the item, press –.

To choose a menu item:

¦ Press  while the items is underlined, or

¦ For menu items followed by an debate value, enter the debate value while the items is underlined. The item and also the discussion value are presented on the vault screen.

Previous Entries # $

After an expression is evaluated, use # and $ to scroll through previous entries, which are stored in the TI-30X Ö memory. You can not retrieve vault entries when in STAT mode. Friend can edit a previous entry and press  to evaluate the new expression.

Last answer %i

The most recently calculated an outcome is stored to the variable Ans. Ans is preserved in memory, even after the TI-30X Ö is turn off. Come recall the worth of Ans:

¦ Press % i (Ans displays on the screen), or

¦ Press any kind of operations key (T, U, F, etc.) as the an initial part of one entry. Ans and the operator space both displayed.

Order the Operations

The TI-30X Ö uses EOSé (Equation operation System) to evaluate expressions.


Expressions within parentheses.


Functions that require a ) and precede the argument, together as sin, log, and also all RÍP menu items.




Functions that are entered after the argument, such as x2 and edge unit modifiers (Ä Å Æ r g).


Exponentiation (^) and roots (x‡).


Negation (M).


Permutations (nPr) and combinations (nCr).


Multiplication, include multiplication, division.


Addition and subtraction.


Conversions (A bÌcÍdÌe, FÍD, 4DMS).


 completes all operations and closes all open up parentheses.

Clearing and also Correcting

Clears one error message.

Clears characters on entry line.

Moves the cursor to last entry in history once screen is clear.


Deletes the character at the cursor. Deletes all personalities to the right when you hold down J; then, deletes 1 personality to the left that the cursor each time friend press J.

% f

Inserts a personality at the cursor.

% {

Clears all storage variables.

% t


Clears all data points there is no exiting STAT mode.


Clears all data points and exits STAT mode.

%  Y or

& & –

Resets the TI-30X Ö. Return unit to default settings; removes memory variables, pending operations, every entries in history, and statistical data; clears constant mode and Ans.

Fractions N %j %O

Fractional calculations can screen fractional or decimal results. Outcomes are instantly simplified.

¦ N enters a fraction. Press N between totality number, numerator, and also denominator. The unit, numerator, and denominator need to be optimistic integers.

¦ % j converts in between fractions and decimals.

¦ % O converts in between mixed numbers and simple fractions.

Pi g

p=3.141592653590 for calculations. p=3.141592654 because that display.

Angle modes I =

I displays a food selection to specify the Angle setting as degrees, radians, or gradients.

= displays a food selection to point out the edge unit modifier— levels (Ä), radians (r), gradients (g), or DMS (Ä Å Æ). It likewise lets you convert an edge to DMS Notation (4DMS).

To set the Angle setting for any component of an entry:

¦ Select the angle mode. Entries room interpreted and also results displayed according come the edge mode, or

¦ Select a unit modifier (Ä Å Æ) for any part of an entry. Entries v unit amendment are taken accordingly, overriding the angle mode.

To convert an entry:

¦ Set the Angle setting to the unit you desire to transform to. Then usage a unit modifier come designate the unit to convert from. (Angles the trigonometric functions transform values within parentheses first.), or
