Thinking of last-minute advice I can give my wife before she takes an algebra placement exam and I end up with: if they ask you to divide by a complex-valued number, refuse.
@nebusj looks like this guy believes in I-M-A-G-I-N-A-R-Y numbers. Next we'll be talking about "ghost numbers".
@nebusj though, in no seriousness, without dividing by complex numbers you can't divide 6 apples among 2+i friends (where one is an imaginary friend).
