Student Misconceptions about Complex Numbers

Asked by Irem Yildirim, teacher on December 23, 1997:
What misconceptions and errors do students have in complex numbers?
Some misconceptions and errors are illustrated in the "fallacious proof that 1=2 using complex numbers", on our web site at

For others, you may want to seek input from other high-school teachers. We've placed your question in the discussion area instead of the question area, in case anybody wants to add to it.
