Hello Evan,

I agree that you have yourself a perfect calculator for your classroom!

I would offer to fix it, but you seem to have a found a real gem.

Check out this TI-83+:

This is one our school calculators. The entire display has been reflected horizontally. No idea why -- it just happened spontaneously.
In fact, later in the day, the display was reflected horizontally AND upside down. Now it is back to just reflected horizontally. (No I did not photoshop these images.) I might be able to fix it by taking out all 5 batteries, but I don't really want to.

For several years I have covered my classroom clock and put up a backwards clock instead. And I have a collection of a dozen watches, some go forward, some go backward (some with forward displays, some with reversed displays, one with a mirrored display) -- I wear a different watch every day. And I have a map of the world in my classroom that is printed with south on top, north on the bottom.

So I didn't know it until today, but THIS is the calculator I have always wanted.

Math question: the composition of a horizontal reflection and a vertical reflection is ... ?

Answer: a 180-degree rotation. So earlier today when it was in reflected-and-upside-down mode, if you turned the calculator upside down, the display looked normal.
