Turning the Calculator On and Off The TI-36X is battery powered. • To turn on the TI-36X , press • To turn off the TI-36X , press memory is retained. APDé (Automatic Power Downé) turns off the TI-36X automatically if no key is pressed for about five minutes.
Display The TI-36X has a two-line display. The first line (Entry Line) displays an entry of up to 88 digits or items (47 for Stat or Stored Operations). Entries begin on the left; those with more than 11 digits scroll to the left.
Menus Some key presses access menus: , and The menu choices are displayed on the screen. Press to scroll through the menu and underline an item. To select an underlined item: • Press while the item is underlined. Or, • For menu items followed by an argument value, enter the argument value while the item is underlined.
Clearing, Correcting, and Resetting Action Action depends on position of the cursor. • If cursor is in the middle of an entry, clears character under the cursor and all characters to the right of the cursor. • If cursor is at the end of an entry, clears the entire entry.
Display Indicators Special indicators may appear in the display to provide additional information about functions or results. Indicator Meaning 2nd function is active. Calculator is rounding results to specified number of places. SCI or ENG Scientific or engineering notation is active.
Order of Operations The TI-36X uses EOSè (Equation Operating System) to evaluate expressions. Order Evaluation Expressions inside parentheses. Functions which need a ) and precede the argument, such as sin, log, and all R/P menu items; Boolean Logic NOT and 2’s complement.
Basic Operations As you press keys, numerals, operators, and results appear on the display. Enters numerals 0 through 9. Adds, subtracts, multiplies, divides. Opens, closes a parenthetical expression. Inserts the decimal point. Enters a negative sign. Completes all operations. Last Answer recalls the value of the most recently calculated result and enters it into the current entry as Ans.

Fractions Fractional calculations can display fractional or decimal results. Results are automatically simplified. Enters a fraction. Press entering whole number, and between numerator and denominator, both of which must be positive integers. To negate a fraction or a mixed number, press before entering the first argument.
Exponents, Roots, and Reciprocals Calculates the square of a value. Raises a value to any power within the range of the calculator. If the number is negative, the power must be an integer. If you include an operation in the exponent, you must use parentheses.
Notation displays the Numeric Notation mode menu. • FLO (default): Displays results in floating notation, with digits to the left and right of the decimal point. • SCI: Displays results in scientific notation. The format of scientific notation is n x 10^p, where 1 { n<10 and p is an integer.
enters the value of p. It is stored internally to 13 digits ( 3.141592653590 ) and displayed to 10 digits ( 3.141592654 ). When multiplying p by a number, you do not need to press ; multiplication is implicit. ³ Find the circumference and the area of a circle having a radius of 5 centimeters.
Memory The TI-36X has five memory variables. You can store a real number or an expression that results in a real number to a memory variable. For storing complex numbers to memory, see page 31. Lets you store values to variables. Recalls the values of variables.
In addition to serving as a memory variable, E stores a seed value to generate a random number when you are using the Probability function (see page 32). ³ A gravel quarry is opening two new pits: one is 350 meters by 560 meters, and the other is 340 meters by 610 meters.
Stored Operations The TI-36X stores two operations, Op1 and Op2. To store an operation to Op1 or Op2 and recall it: 1. Press 2. Enter the operation, beginning with an operator (such as +, M, Q, P, or ^). You can store any combination of numbers, operators, and menu items and their arguments, to a limit of 47 characters or items.
