Modes

Before starting a calculation, you must first enter the correct mode.

To perform this type of
calculation:

Basic arithmetic calculations [MODE] [0] COMP
Standard deviation calculations [MODE] [.] SD
Calculations using degrees [MODE] [4] DEG
Calculations using radians [MODE] [5] RAD
Calculations using grads [MODE] [6] GRA
Number of decimal place
specification

Number of significant digit
specification

Cancels FIX and SCI settings [MODE] [9] NORM

• Display indicators show the current mode setting. If there is no display shown,
this indicates COMP mode.

• The COMP and SD modes can be used in combination with the angle unit
settings.

Perform this key
operation:

[MODE] [7] [x]
(x = # of decimal places and
ranges from 0 – 9)
[MODE] [8] [x]
(x = # of significant digits and
ranges from 0 – 9)

Name of mode:

FIX

SCI

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.
[ON] 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.

Basic Calculations
Be sure to press [AC] when beginning a new calculation.
[+] [ - ] [x] [÷] Addition, subtraction, multiplication, and division
[=] Performs calculation
[+/-] Changes the sign of a displayed value. You must enter the value

first.

[(] [)] Left and right 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] [π] This will input the numerical value for π.
[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 3

The answer displayed is 8.

2

, to swap 3 and 2, press [3] [xy] [2] [SHIFT] [X- Y ] [= ].
