Question about Texas Instruments TI-84 Plus Calculator
It appears that a student of mine has played with her calculator, and it displays everything you type upside down. I cleared the RAM and nothing. Help.

Was it a prank ?
I have read that to invert the LCD-screen you just flip the polarisation-plate (the plastic film that sits over the LCD display) 180º, that is , upside down.

Wow. Just wow. How did that person do that?! Anyways, try resetting ALL of the memory, and see if that helps, if not, ask the student what she did so that it can be reversed (probably by doing the same steps in the opposite order.
