AI Thread Summary
The TI-89 calculator can mistakenly assign a value to the variable 'x', such as setting it to 2, which can cause confusion when performing calculations. This issue can arise if a user inadvertently inputs a command like "x=2". To resolve this, the user can clear all variable assignments by pressing F6 and selecting "clear a-z". Additionally, the calculator allows users to assign values to variables using the STO (store) function, which can lead to similar situations if not monitored. Understanding these functions can help prevent unexpected variable assignments in the future.

I just got a new TI-89 today, and it's really nice. The problem is, it thinks that x==2 for some reason. Any other variable works fine, but if I just do x and press enter, it says 2; and x^2 says 4. Not sure why, and I'm positive I never told it to do that. Any idea how to fix it? Thanks in advance.

NVM, I figured out how to fix it (f6; clear a-z), but I'm not sure how I set it in the first place.
 
You may have input "x=2". Been a few years since I used my TI-89, but I think that happened to me a lot.

You can set it by typing '2' then STO > (just above the 'ON' button) and then the variable you want (in your case 'x'. This will set x equal to 2.

Well, the date has now passed, and Windows 10 is no longer supported. Hopefully, the readers of this forum have done one of the many ways this issue can be handled. If not, do a YouTube search and a smorgasbord of solutions will be returned. What I want to mention is that I chose to use a debloated Windows from a debloater. There are many available options, e.g., Chris Titus Utilities (I used a product called Velotic, which also features AI to prevent your computer from overheating etc...
