My TI-84 graphing calculator has a blank graph. Maybe because I was playing with the cbr/cbl app or it could have been some other graph. When i do a graph, there is no x or y axis.

Press the 2nd Button then the ZOOM button. Make sure that AxesOn is highlighted. If not, move your cursor down until you on AxesOn and press ENTER.

If AxesOn is highlighted, then it is probably your window. Press ZOOM, then 6.

Uninstalling the Application does not erase it from the calculator, it disables it from interfering with the normal graphing modes. Below are the steps to successfully uninstall the Application.

Can not reset calculator. Keep getting + sign when press enter


If the TI-84 does not function even though you are sure that the
batteries are fresh, you can try manually resetting it by following steps:

1. Remove all of the AAA batteries from the graphing handheld

2. Press and hold the ON key for ten seconds

3. Replace the batteries

4. Turn on the unit

When you reset your graphing handheld, the contrast sometimes
changes. If the screen is faded or blank, adjust the contrast by
pressing 2nd and releasing up-arrow or down-arrow keys.

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.

The first solution will allow you to watch your calculator graph two equations simultaneously rather than finishing one before graphing the next; it won't solve the problem of having the calculator unselect one equation when you select a second. To fix that problem, try the following:
