If you feel a bit insecure about conveying your ideas to complete strangers, you should approach a local math professor. Stealing ideas from others is just about the worst offense a professional scientist/mathematician can commit, it goes against the very ethos of research.
No self-respecting professional would dare to commit this crime, so you really ought to present your ideas to someone knowledgeable in the field.
Also remember that as long as you possesses evidence of PRIORITY, you are the one who will be regarded as the originator of an idea.
Posts here at PF (and, not the least, your teacher's testimonial!) are such evidence, so you should consider this a safe enough place to expound a bit.
However, as matt grime also noted, steel yourself as follows:
"Most probably, what I've thought out is either well-known or dead wrong; it is only a slim chance that I might be right AND having found out something new&important".
This is not said in order to belittle you, or dismiss your ideas out of hand, but is simply a conclusion drawn from experience:
In the 20th century, virtually NOTHING has been added to maths from individuals who haven't studied maths at least for a few years at university level.
(Ramanurjan might be a counter-example, who, however, do not invalidate the general trend).
Modern maths is so rich and encompassing, so that to learn the necessary foundations of today's problems actually requires years of intensive study I severely doubt you are old enough to have gone through.
However, it on this level that original, creative research (usually/invariably) has its starting-point.
Again, this is NOT said in order to dismiss your ideas out of hand, but that assuming you've hit upon something correct&valid in respect to complex numbers (and I have no reason of doubting you're correct yet), then you are in all probability TOO LATE
(someone else have beaten you).
