I searched on this site but I found posts asking for books on complex analysis which I guess is not what I want.
I don't think these types of problems are covered in a analysis book but I don't know. I think I want a book on algebra of complex numbers.
Are these topics covered in analysis book ? If not, please suggests some books on this topic. I guess my question is bit vague, sorry for that. :).
As suggested in the comments I would like to have books similar to Complex Numbers from A to ...Z.
