Casio fx-260 solar fraction calculator

Refer to user manual at this link fx-82SOLAR_260SOLAR II_260SOLAR II NF (casio.com) It will tell you the limitations.

You can switch between Rads/Deg/Grads. Deg is the one you want to use. So, to answer your question, the "DEG" is suppose to be there so that you know what mode you are using. If you don't have the manual, here it is:

The FX-901 calculator seems to be the equivalent of the FX 260 Solar sold in North America. It does fraction calculations, permutation, statistics but lack the Equation Solver.
You cannot use it to solve equations.
Casio Scientific calculators that can handle equation solving are the FX-115 and FX-991.
Simplify your first equation by dividing all its terms by 3, then use elimination to carry out the solution by hand.

You can always convert a fraction to a decimal. The reverse may not alwas be possible.
Look at the example on the screen capture.

To force a fraction to be displayed as a decimal number put a decimal mark at the end of the numerator OR the denominator. Fraction/decimal result is always decimal.

Hello,
Yes it does. All scientific calculators do logs, power, roots, exponential, trigonometric functions. Most do also hyperbolic and inverse hyperbolic functions.
Hope it helps.

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).
