To change the task number you must press and hold % (rate set) for 3 to 5 seconds, should appear tax XX %, now type your tax number and press % again and AC. To test type "100" press TAX + and the result should be 110, if your tax rate is 10% for example.

I am using my Casio fx-300MS and have somehow gotten into the display where it puts my answers in exponential form; 5+5 = 1.0 exp10 to the 1. How do I return to getting my answers in standard form?

Display Format

To change the exponential display format, press the [MODE] key 3 times.

Fixed number of decimal places:

Press 1: Scientific Notation: 0

Press 2: SCI: 0

Press 3: NORM

You will then be prompted for NORM 1 or NORM 2. CHOOSE NORM 1

To return the calculation mode and setup to the initial defaults, press [SHIFT] [CLR] [2]

Calculation mode COMP

Angle unit Deg

Exponential display format Norm 1

To convert an angle from degrees (decimal degrees) to the sexagesimal notation (deg, min, seconds) use the key [DMS] the one between [(-) and [hyp].
Everytime you press the key, the displayed result is cast in the other form
EX; 12.58 [DMS] gives 12 deg 34 min 48 sec.
Suggestion: If you are doing many calculations with the sexagesimal format, use the decimal degree format, and only when you find the final result do you convert it to DMS.
Hope it helps.

The [MODE] key can be used to select the modes described below.
Important! The following is a general explanation of Scientific Calculator modes. Note that your calculator may not include all of the modes described here.
1) Calculation Modes
Before performing a calculation, you first need to select the appropriate calculation mode.
COMP: Basic arithmetric calculations
(arithmetic operations, trigonometric functions, etc.)
COMPLEX: Complex number calculations
SD: Single-variable statistical calculations
(sample standard deviation, etc.)
LR or REG: Paired-variable statistical calculations
(linear regression statistical calculations, etc.)
BASE or BASE-n: Binary, octal, decimal, hexadecimal number system calculations
MAT: Matrix calculations (determinants, etc.)
VCT: Vector calculations
EQU: nth degree equations, simultaneous equations
2) Display Settings
Use these settings to control how calculation results are displayed.
Note that changing the Fix and Sci settings does not affect internal calculation results.
Norm: Exponential display format and cancels the currently configured Fix and Sci settings.
Fix: Specifies a fixed number of digits to the right of the decimal place.
Sci: Specifies a fixed number of significant digits.
3) Angle Unit Setting
(90°=?/2 radians=100 grads)
Deg: Degrees
Rad: Radians
Gra: Grads
4) Engineering Mode
Use this mode when you want to input and perform calculations using engineering symbols.

Problem with Casio FX 260 Calculator

Read the screen capture about the MODES of this calculators. DEG,RAD, and GRAD remind the user that the angle units in trigonometric function calculations and coordinate conversions are in degrees, radians or grads. They have nothing to do with the other calculations you are doing.


You can only remove DEG by changing the angle unit to RADians or GRADs. In so doing, the new unit indicator (RAD, GRAD) will be displayed instead. There is no point worrying about the angle unit indicator unless you are performing coordinate conversions or calculating trigonometric functions or the inverse trigonometric functions.

MODE 9 cancels the FIX display format: decimal are displayed with a fixed number of decimal places (set by the user). After this key sequence the decimal display format reverts to NORM(al).
