TI-89 Problem - Fixing x==2 Issue

[mjayhunt]

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.
