To undo this, go to F6, then select Clear a-z.In summary, the speaker recently acquired a new TI-89 calculator and is experiencing an issue where the variable x is automatically set to 2 when entered into the calculator. They were able to fix the issue by clearing the a-z values, but are unsure how the setting was initially changed. Another speaker suggests that it may have been accidentally set by inputting "x=2" and provides instructions on how to undo this.

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.

## 1. How do I fix the "x==2" issue on my TI-89 calculator?

To fix this issue, you will need to reset your calculator by pressing the "2nd" button followed by the "0" button. This will bring up the "Mem Mgmt/Del" menu. From there, select "1: All RAM" and then select "2: Reset". This will reset your calculator to its factory settings and should resolve the "x==2" issue.

## 2. Why does my TI-89 calculator keep showing "x==2" instead of my calculation?

This issue may occur if the previous calculation was not entered correctly or if there is a problem with the calculator's memory. To fix this, try resetting your calculator or clearing the previous calculation by pressing the "ESC" button.

## 3. Can I prevent the "x==2" issue from happening again?

To prevent this issue from happening again, make sure to enter calculations correctly and to clear any previous calculations before entering a new one. It may also help to periodically reset your calculator to clear any potential memory issues.

## 4. Will resetting my calculator erase all my saved data?

Yes, resetting your TI-89 calculator will erase all data, including saved equations and programs. It is important to back up any important data before resetting your calculator.

## 5. What should I do if the "x==2" issue persists after resetting my calculator?

If the issue persists after resetting your calculator, it may be a hardware issue and you may need to contact the manufacturer for further assistance. It is also recommended to try updating your calculator's operating system to see if that resolves the issue.
