Alternatively, it may also show the status of a setting. The following is a list of the display indicators along with a description: Indicator Meaning FIX Number of decimal places is fixed. SCI Number of significant digits is fixed. SIMP Displayed fraction can be simplified. R Remainder of division. ‘ 3-digit separator ( ) Parentheses M A value is stored in memory. E Error + Addition - Subtraction x Multiplication . Division .R Division with remainder = Result D Degrees R Radians G Grads STAT Statistics mode. The calculator is in the COMP mode when this indicator is not on the display. xy The yth power of x. x1/y The yth root of x. F1 Data is stored in constant memory F1. F2 Data is stored in constant memory F2. S [SHIFT] was pressed Hyp Hyperbolic function Display Set Up The FX-65 allows you to change the display format for the following: Fixed number decimal places Number of significant digits in scientific notation Engineering notation mode Key Function [FIX] n Sets the number of decimal places according to the value you input for n (0 – 9). [FIX] [.] Clears the decimal place setting. [SHIFT] [SCI] n Sets the number of significant digits according to the value you input for n (0 – 9). [SHIFT] [SCI] [.] Clear the scientific notation setting. [SHIFT] [ENG] Enters the engineering notation mode and normalizes the displayed value so its exponent is a positive multiple of three. [SHIFT] [ENG] Enters the engineering notation mode and normalizes the displayed value so its exponent is a negative multiple of three. Basic Arithmetic Calculations Basic Functions and Operations The following are the basic functions and operations of the calculator. Backspaces and deletes the right digit of a displayed input value. [AC] Turns power on. [C] Clears the displayed input value. [SHIFT] Shifts the keyboard and accesses functions marked above the keys. Note: There is no power off key. The calculator automatically turns off about six minutes after you finish using it. Basic Calculations Be sure to press [AC] when beginning a new calculation. [+] [ - ] [x] [.] Addition, subtraction, multiplication, and division .R Division with remainder. The display shows up to (6) digits for the quotient and (4) digits for the remainder. [=] Performs calculation [+/-] Changes the sign of a displayed value. You must enter the value first. [(] [)] Left and right parentheses. You can have up to 18 sets of nested parentheses. Note: The calculator uses “order of operations”. So for 2 + 3 x 4, you do not need parentheses around 3 x 4. The calculator will calculate 3 x 4, then add 2. [SHIFT] [.] In degree mode, this will input the numerical value for .. In radian mode, the “.” symbol will be displayed. [SHIFT] [X-Y] Swaps the value of x and y in power and root calculations. Also swaps the minuend and subtrahend in subtraction calculations. Example: for 32, to swap 3 and 2, press [3] [xy] [2] [SHIFT] [X-Y] [=]. The answer displayed is 8. Fraction calculations and simplification • You can perform addition, subtraction, multiplication, and division. • The result of a calculation that mixes fractions and decimal values is displayed as a decimal value. • Using the [b/c] key, you can enter a fraction with up to 4 digits in both the numerator and denominator. • Results can have up to four digits each for integer, numerator, and denominator. If any part is longer, value is displayed as decimal with error symbol E. Be sure to press [AC] when beginning a new calculation. [b/c] Inputs the numerator (b) /denominator (c) of a fraction in the form b/c. Example: to input . , press [1] [b/c] [2]. [a] Inputs the integer part of a fraction (mixed number). Example: to input 2 ., press [2] [a] [1] [b/c] [2]. [SHIFT] Converts the displayed value between mixed number and improper [a b/c – d/c] fraction. [=] When “SIMP” is displayed, pressing [=] will reduce the fraction to its simplest form. [SIMP] Simplifies a fraction by the smallest divisor possible. The divisor being used appears on the display for a moment, followed by the simplified fraction. n [SIMP] ...
