I have just bought this calculator Casio FX-82 Solar Fraction at a jumble sale and have been playing around with it. Now, whenever I start it up it shows DEG in the display and I can't get rid of it. Is it supposed to do this? If not, what can I do to put it right? I am wanting to put it on Ebay!
I'm not technical, so if you know the solution, please keep it simple, thank you.

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 Ti83/84PLUS are a lot more advanced than the TI-30XA because thaeu can graphs, statistics, calculus etc. But they lack a key for the % function, and a key for the fraction manipulation, the angle unit conversions (deg, radians, et grads) and they are a lot more expensive than the TI30XA.
Before your daughter finishes high school, you will eventually have to buy her a graphing calculator but right now a TI83/84Plus calculator seems like overkill. Besides some teachers may not let students have graphing calculators during exams.
Honestly I suggest you buy the TI-30XA Solar version. There are some new nifty calculators manufactured by Casio (Casio FX-115ES, FX-991ES, FX-300ES), Sharp (El-506W, 516W ). The beautiful thing about these new kinds of calculators is that you can configure them to use the Textbook display: equations and expressions can be entered as they would appear in textbooks. The Casios are called Natural Display and the Sharps are know as WriteView models.
In fairness to Texas Instruments, they too have calculators that incorporate that display format but I do not know the exact model numbers (maybe TI34XII multiview).
The DEG indicator has absolutely nothing to do with division, fraction or other operations. It is relevant only when you are calculating trigonometric functions (Sine, Cosine Tangent and their inverse functions.)
When you are calculating trigonometric functions the results depend on the angle unit the calculator is configured for DEG >> angle values are in degrees. RAD>> angle value are in radians
From the equivalence 180 deg =Pi radians you get 1 rad= 180deg/Pi=180 deg/3.14..=57.29577951 degrees.
The DEG indicator merely reminds you that angles are in DEG. If you
change the unit to RADians the RAD indicator will be displayed instread.
