I think you accidentally a verb.

But, yes. Casio fx-991EX. It's designed for schools, I think, but at the time it was the most advanced one they made that wasn't a graphing calculator, since I figured that if I ever wanted to draw a graph I'd just fire up "Grapher", which is still bundled with every Mac.

In about a decade I think I've done that once. The Casio is great.

Looks like it's discontinued now? I guess the fx-9910CW is the replacement. They made the buttons circular. Weird.
