How do I get rid of the "FIX" at the top of calculator?

Turn calculator on. Press the STAT button. In the new screen that displays, press 5:SetUpEditor, then ENTER. The deleted lists will be restored. Any data that was in them will not be recovered.

Try playing with the buttons on the bottom right. The M+, M-, and Mrc. You should be able to clear the "M" fairly easily.

I am sorry to disagree with you. There is no such option when you open the Y= editor. Is it possible you have seen this option in Casio calculators? Or in some third party programs?

Cheer up, the calculator can display UP to 10 digits, no more. Internal memory keeps 12 digits. So clearly, this calculator is not fit to handle the precision you apparently are seeking. It may be time to look for a more capable calculator.

The DEG is merely indicating that the angular mode is set to degrees. If you want to change it to radians or grads, press SHIFT MODE and make your selection.

Likewise, the FIX is merely indicating that the calculator is displaying numbers in fixed decimal notation. If you're not seeing any digits to the right of the decimal point, then you're in FIX 0 mode. To change it, press SHIFT MODE. You can choose FIX and the calculator will prompt for the number of digits, or you can select NORM.

You need to install the OS
hope it will help

Your calculator is set to display results in scientific notation. To change this, press MODE, highlight "NORMAL" on the top line, press ENTER, and then 2ND [QUIT].

What is BIN at the top of the screen? How do you get rid of it?

Hello,
Press the reset button on the back of the unit. As to the things you want to get rid off, if they are on the top of the screen, they are indicators, to let you see what mode you are using. Some will change when you chande operation mode. There is nothing you can do about it.
However if these symbols are in the center of screen , with numbers to there left (a different number for each) they may be part of the setup procedure. During the setup procedure you are expected to configure your calculator in the mode relevant to the calculations you intend to perform.
What is an upside down p ? Could it be just a b? (as in binary). That is a mode of operation.
Hope it helps.

Hello,
The top of the screen displays reminders on the current configuration of the calculator. The FIX will disappear if you change number display to SCIentific or ENGineering, but it will be replaced by SCI or ENG. Why does it bother you, since that part is reserved for the calculator's usage?
Hope it helps.
