    Ti-89
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.
 
In my discussions elsewhere, I've noticed a lot of disagreement regarding AI. A question that comes up is, "Is AI hype?" Unfortunately, when this question is asked, the one asking, as far as I can tell, may mean one of three things which can lead to lots of confusion. I'll list them out now for clarity. 1. Can AI do everything a human can do and how close are we to that? 2. Are corporations and governments using the promise of AI to gain more power for themselves? 3. Are AI and transhumans...
Sorry if 'Profile Badge' is not the correct term. I have an MS 365 subscription and I've noticed on my Word documents the small circle with my initials in it is sometimes different in colour document to document (it's the circle at the top right of the doc, that, when you hover over it it tells you you're signed in; if you click on it you get a bit more info). Last night I had four docs with a red circle, one with blue. When I closed the blue and opened it again it was red. Today I have 3...
