Well, this week I have a test on my worst mathematics topic so far. Complex Number. For me, someone who's not that bright, this is simply incomprehensible. I was wondering if someone could explain, in simple language and in digestable way, how to:

- Work with complex numbers and learning to equate them
- Cis form (cos thetha + isin theta) and all that rubbish
- De Moivre's Theorem

All the aid is strongly appreciated!

Please make it simple for me!
