I really need to factor minus one from -x-yI. I can do -[x+yI] and -{x+yI}. I cannot do -(x+yI).
Well, i really don't have these numbers exactly. They are produced within a Maple program.
I have something like ab, where a is the number x+yI. The little trick -`a`b will not work because
of the rather involved form of "a".
Thank you!
