Examples: view the last page of these instructions because that keystroke examples that demonstrate countless of the TI-30X Ö functions. Instances assume all default settings.

& turns on the TI-30X Ö. % ‘ turns it 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 memory space retained.
2-Line Display: The an initial line (Entry Line) screens an entry of approximately 88 number (or 47 digits for Stat or constant Entry Line). Entries begin on the left; those with much more than 11 digits scroll to the right. Press ! and “ to scroll the line. Press % ! or % “ to move the cursor immediately to the start or finish of the entry.
The 2nd line (Result Line) displays a result of approximately 10 digits, add to a decimal point, a an adverse sign, a “x10” indicator, and also a 2-digit hopeful or an unfavorable exponent. Outcomes that exceed the digit limit are presented in clinical Notation.
Scientific or design Notation.
Angle mode (degrees, radians, or gradients).
Constant mode is on.
Precedes the exponent in clinical or design Notation.
An entry is save on computer in memory before and/or after ~ the active screen. Press # and $ to scroll.
An entry or menu displays past 11 digits. Press ! or “ to scroll.
2nd Functions: % displays the 2nd indicator, and then selects the 2nd function (printed above keys) the the next crucial pressed. For example, % b 25 E calculates the square source of 25 and returns the result, 5.
Menus: certain TI-30X Ö keys display menus: z,
% h, L, % t, u, % w,
H, I, =, % k, % d, % ‚, and
Press ! or “ to move the cursor and also underline a menu
item. To return to the previous display screen without picking the item, press –.
To select a food selection item:
¦ Press while the item is underlined, or
¦ For menu items complied with by an dispute value, go into the argument value while the items is underlined. The item and the discussion value are displayed on the vault screen.
Previous Entries # $
After an expression is evaluated, use # and $ to scroll v previous entries, which room stored in the TI-30X Ö memory. You can not retrieve vault entries if in STAT mode. Friend can modify a ahead entry and press to evaluate the brand-new expression.
Last prize %i
The most recently calculated result is stored come the variable Ans. Ans is kept in memory, even after the TI-30X Ö is turned off. To recall the worth of Ans:
¦ Press % i (Ans displays top top the screen), or
¦ Press any kind of operations crucial (T, U, F, etc.) as the first part of one entry. Ans and the operator are both displayed.Order the Operations
The TI-30X Ö uses EOSé (Equation operation System) to advice expressions.
Expressions within parentheses.
Functions that need a ) and head the argument, such as sin, log, and all RÍP menu items.
Functions the are gotten in after the argument, such as x2 and edge unit modifiers (Ä Å Æ r g).
Exponentiation (^) and roots (x‡).
Permutations (nPr) and also combinations (nCr).
Multiplication, implied multiplication, division.
Addition and also subtraction.
Conversions (A bÌcÍdÌe, FÍD, 4DMS).
completes all operations and also closes all open parentheses.
Clears one error message.
Clears personalities on entrance line.
Moves the cursor to critical entry in history once screen is clear.
Deletes the personality at the cursor. Deletes all characters to the right as soon as you organize down J; then, deletes 1 character to the left of the cursor each time friend press J.
Inserts a character at the cursor.
Clears all storage variables.
Clears all data points there is no exiting STAT mode.
Clears all data points and also 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 also statistical data; clears consistent mode and Ans.
Fractions N %j %O
Fractional calculations can display fractional or decimal results. Results are automatically 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 between fractions and also decimals.
¦ % O converts between mixed numbers and an easy fractions.
p=3.141592653590 for calculations. p=3.141592654 for display.
Angle settings I =
I displays a food selection to clues the Angle setting as degrees, radians, or gradients.
= displays a menu to specify the angle unit modifier— degrees (Ä), radians (r), gradients (g), or DMS (Ä Å Æ). It also lets you convert an angle to DMS Notation (4DMS).

To set the Angle mode for any component of an entry:
¦ Select the edge mode. Entries space interpreted and also results displayed according come the edge mode, or
¦ Select a unit comprehensive (Ä Å Æ) for any component of one entry. Entries through unit amendment are interpreted accordingly, overriding the angle mode.
To convert an entry:
¦ Set the Angle setting to the unit you want to convert to. Then use a unit modifier come designate the unit to convert from. (Angles the trigonometric functions transform values inside parentheses first.), or
