Try to imagine that teacher whose need to instruct students one-by-one to fix this problem.
And try to imagine me, an engineer, how I disappointed when I turned on complex mode and all the negative real numbers are vanished.

I couldn't believe that a calculator would do this, so I tried it on the fx-9750giii that I got recently, and holy crap, it turns the real number "-2" into the complex number "2∠180". But inconsistently, it doesn't turn the real number "2" into the complex number "2∠0". I think I would be happier if it was consistent. So the expression "2-4" becomes "2∠180". No other (non-Casio) calculator that I know does this, a quick check: TI-83+/84+, TI-89T, HP-42S/Free42, none of them do this.

Ha, the Casio is still one of the best bang for the buck, and I got other plans for it...
