Hello,
Natively the OS of the TI84 does not use tabs: It only uses menus and submenus. These tabs come from the game or application you were running before. Terminate the application and clear the RAM because third party applications have a tendency to linger in memory.
Hope it helps.

    Have you run the Inequalz application? It too uses Tabs.
    The inequalz application takes over the graphing capabilities from the native OS. To recover the usual graphing environment you must unload Inequalz from memory.


    1. Press [Apps]

    2. If you see Inequalz in the list of Apps, press the number that corresponds to it and press [ENTER]

    3. If you do not see Inequalz in the list uses down Arrow to point to it and press [ENTER]

    4. In the screen "Inequalz Running" press [2:Quit Inequal]

    5. The application will be unloaded from memory. It is still in the calculator and can be executed when or if needed.

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.

How do i solve this problem 3x+25=5x using my TI 84 plus


i think there are programs but with something as simple as that you should be able to work it out manually....
3x+25-5x=5x-5x
-2x+25-25=0-25
-2x=-25
x=25/2 or 12.5
