General Information

Examples: check out the last page of this instructions because that keystroke examples that demonstrate numerous of the TI-30X Ö functions. Examples assume all default settings.

& turns on the TI-30X Ö. % ‘ turns it off and also clears the display.

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

2-Line Display: The very first line (Entry Line) display screens an entry of up to 88 number (or 47 digits for Stat or continuous Entry Line). Entries start on the left; those with more than 11 digits role to the right. Press ! and “ to scroll the line. Press % ! or % “ to move the cursor instantly to the start or finish of the entry.

The second line (Result Line) display screens a result of approximately 10 digits, to add a decimal point, a an unfavorable sign, a “x10” indicator, and a 2-digit optimistic or an unfavorable exponent. Outcomes that exceed the digit limit are presented in scientific Notation.




2nd function.


Hyperbolic function.


Fixed-decimal setting.


Scientific or design Notation.


Statistical mode.



Angle mode (degrees, radians, or gradients).


Constant mode is on.


Precedes the exponent in clinical or engineering Notation.

º »

An entry is save on computer in memory prior to and/or after ~ the active screen. Press # and $ to scroll.

¹ ¸

An entry or menu displays past 11 digits. Press ! or “ to scroll.

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

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

% h, L, % t, u, % w,

H, I, =, % k, % d, % ‚, and

% .

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

item. To go back to the previous display without choosing the item, press –.

To select a food selection item:

¦ Press  while the item is underlined, or

¦ For menu items adhered to by an argument value, get in the dispute value while the items is underlined. The item and also the discussion value are displayed 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. You can modify a previous entry and press  to evaluate the new expression.

Last answer %i

The many recently calculated an outcome is stored come the variable Ans. Ans is kept in memory, even after the TI-30X Ö is turned off. Come recall the worth of Ans:

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

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

Order of Operations

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


Expressions within parentheses.


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




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


Exponentiation (^) and root (x‡).


Negation (M).


Permutations (nPr) and also combinations (nCr).


Multiplication, comprise multiplication, division.


Addition and subtraction.


Conversions (A bÌcÍdÌe, FÍD, 4DMS).


 completes every operations and closes all open up parentheses.

Clearing and Correcting

Clears an error message.

Clears personalities on entry line.

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


Deletes the character at the cursor. Deletes all characters to the right once you organize down J; then, deletes 1 character to the left of the cursor every time friend press J.

% f

Inserts a personality at the cursor.

% {

Clears all memory variables.

% t


Clears all data points without exiting STAT mode.


Clears all data points and exits STAT mode.

%  Y or

& & –

Resets the TI-30X Ö. Returns unit come default settings; gets rid of memory variables, pending operations, all entries in history, and also statistical data; clears continuous mode and Ans.

Fractions N %j %O

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

¦ N enters a fraction. Press N between whole number, numerator, and denominator. The unit, numerator, and denominator have to be optimistic integers.

¦ % j converts in between fractions and decimals.

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

Pi g

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

Angle settings I =

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

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

To collection the Angle mode for any part of an entry:

¦ Select the angle mode. Entries room interpreted and results presented according to the angle mode, or

¦ Select a unit full (Ä Å Æ) for any part of one entry. Entries through unit modification are interpreted accordingly, overriding the edge mode.

To transform an entry:

¦ Set the Angle mode to the unit you want to convert to. Then use a unit modifier come designate the unit to convert from. (Angles of trigonometric functions transform values within parentheses first.), or
