Basic Arithmetic Calculations

Making Corrections During Input

• Use the left and right arrows on the REPLAY function to move the cursor to the

location you want to correct.

• Press [DEL] to delete at the current cursor position

• Press [SHIFT] [INS] to change the cursor to an insert cursor [ ].

Replay Function

Every time you perform a calculation, the replay function stores the calculation formula
and its result in replay memory. Pressing the up arrow displays the formula and result of
the calculation you last performed. If you continue to press the up arrow, you will scroll
sequentially through your last calculations (most recent to oldest).

Notes:
Replay memory capacity is 128 bytes.
Pressing AC will not clear the replay memory.
If you want to clear the replay memory, press the ON key or reset the modes/settings:
Press [SHIFT] [C L R] [2] [=] or [SHIF T ] [CLR] [3] [=] .

Order of Operations

The calculator uses “order of operations”.
Examples: 2 + 3 x 4 = 14 You do not need parentheses around 3 x 4.
(2 + 3) x 4 = 20 Use Replay and [SHIFT] [INS] to add parentheses.
Blinking [ ] is the insert cursor.

- 2
(- 2)

Display Format

To change the exponential display format, press the [MODE] key 3 times.
Fixed number of decimal places: Press 1: FIX

Scientific Notation: Press 2: SCI

Normal Notation: Press 3: NORM

2

= - 4

2

= 4

You will then be prompted for the number of
decimal places (0 – 9).

You will then be prompted for the number of
significant digits (0 – 9).

You will then be prompted for NORM 1 or NORM 2.
NORM 1 uses exponential notation for integers with

more than 10 digits and decimal values with more
than 2 decimal places. Ex/ 1 ÷ 1000 = 1 x 10

-3

NORM 2 uses exponential notation for integers with
more than 10 digits and decimal values with more
than 9 decimal places. Ex/ 1 ÷ 1000 = .001

Fraction Display

You can use the display set up screen to specify the display format when a fraction
calculation result is greater than one. To set the fraction display, press the [MODE] key
4 times and press “1” for Display (DISP).

Mixed Fraction: Press 1: a b/c

Improper Fraction: Press 2: d/c

Decimal-Fraction Conversion

Examples:
Keystrokes Display
Enter [2.75] [=] 2.75

Press [a b/c] 2 3 4
[SHIFT] [d/c] 11 4

Angle Display

To set the angle unit at degrees, radians, or grads, press the [MODE] key 2 times.
Degrees Press 1
Radians Press 2
Grads Press 3

Initial Defaults

To return the calculation mode and setup to the initial defaults, press [SHIFT] [CLR] [2]
[=]. This will return the calculator to the following settings:

Calculation mode COMP
Angle unit Deg
Exponential display format Norm 1
Fraction display format a b/c
Decimal point character Dot

Percentage Calculations

Examples:
To find percentage of

a number.
12% of 15 [15] [x] [12] [SHIFT] [%] 1.8

To calculate percentage
of one number to another.
What percentage of 80 is 40? [40] [
