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.

Screen upside down

I have seen a lot of questions of this sort but I have never this this inversion in a calculator. You could try to reinstall the Operating system. For the TI83 Plus, the last OS version is 1.19. If it is a TI84Plus/TI83 Plus Silver Edition the OS version number is around version 2.55 MP.

How do you move the 'd' sympol off the casio fx-82ms ?

There are two separate issues here.

The "D" at the top of the screen indicates that the angular mode is set to degrees. You can change the mode by pressing the MODE key repeatedly until you get to the "Deg Rad Gra" screen and then choosing one of them, but no matter which one you choose you'll get a letter at the top of the screen reminding you of the current mode.

To change the way numbers are displayed, press the MODE key repeatedly until you get to the "Fix Sci Norm" screen and then choosing one of them. You can choose Fix and then press a digit specifying the number of digits after the decimal point, or choose one of the Norm modes and let the calculator show all nonzero digits after the decimal point.

For more details, see the manual:

How do I get the little rad and fix to go away? I just want deg to be at the top. Thanks

Press the DRG button to cycle through the three angular modes.

To get rid of the "FIX", press SETUP 0 and then choose something other than FIX. Your choices are SCI, ENG, NORM1, and NORM2 (press down-arrow to see the last two).

For my Ti-84 plus edition when I type in the graph equations there is an equals sign, a greater than sign, a less than sign, and some other signs at the bottom of the screen. How do I get rid of this?

You, or someone else played with INEQALZ (inequalty graphing) applications. The problem is thet it remains in memory and takes over the graphing duties from the native OS. If you do not want Inequalz to manage the graphing, just kick it out of memory.
Press [APPS¨] key.
Use arrows to scroll through the list of APPS.
Locate INEQALZ and highlight it.
Press [ENTER]
In the new screen INEQALZ RUNNING, press the number that corresponds to the option Uninstall.

I have fix and deg on my fx 992s and I am only getting results and can only enter numbers to 1 dp. How do I remove this?

Ok. Press [MODE] key three times until you see a screen that shows Fix SCI and NORM. Under FIX you have 1, under SCI you have 2 and under NORM you have 3.

You cannot remove FIX, unless you replace it with another display MODE (SCI or NORM or ENGineering).

You cannot remove DEG unless you change angle unit to RADians or GRAds.
To set angle Unit You start by pressing MODE twice to get a screen that displays DEG, RAD and GRA and below them 1, 2 , qnd 3. If you press 2 the angle unit will be set to Radians. DEG will disappear, but RAD will be shown.

Whatever the display format for numbers (FIX, SCI, NORM, ENG) you can always enter numbers of any length. It is their displaying that is affected by the FIX,SCI, etc. mode.

If you want more than 1 decimal digit, press [MODE] three times, then select 1: FIX. You will be asked to select the number of decimal digits (from 0 to 9). You could take 2, 3 or 4, or anything you want.

  1. To summarize: Indicators on screen reflect the configuration or mode you are in.
  2. They can be replaced by others but you cannot clear the screen of the indicators.
  3. You can select the number of decimal digits in your results,
  4. but there is no restriction on the numbers you enter.

Screen is upside down as I type

Wow. Just wow. How did that person do that?! Anyways, try resetting ALL of the memory, and see if that helps, if not, ask the student what she did so that it can be reversed (probably by doing the same steps in the opposite order.

Get rid of the RAD

You use the key combination [2ndF][DRG]. Every time you press the two keys in sequence it changes to the next angle unit. If your calculator is on RAD, you press [2ndF][DRG] once to change to Grads, and another time [2ndF][DRG] to change to degrees.
Hope it helps

On the screen appears <<>> instead of numbers that i type

try resetting it... Will probably rid you of your problem.

2nd>Mem(+ sign)>reset> right 2c(ALL at top should be highlighted)>yes

You will need to reload all your programs, and while your at it you should probably update the OS from the TI site...

Good Luck
