Real and Imaginary Numbers
I thought I should give Real and Imaginary Numbers their own pages, so here they are:
I have tried to express the ideas simply, so please let me know:
* if it is easy to understand
* if I have over-simplified
* or any ideas you might have for improving

Re: Real and Imaginary Numbers
Hmmm that's pretty cool, good job on those pages 
. Aren't imaginary*real numbers complex, and not imaginary?

Nice page math teacher finds it useful

Re: Real and Imaginary Numbers
Very nice pages. I can't see any errors on there, and everything is very well explained, as always. You've got me intrigued by the non-real numbers that mathematicians like to play with though.
To Toast, multiplying a real and an imaginary number together will indeed get you a complex number, but only because every number ever is complex. The result will also be imaginary. You get exclusively complex numbers by adding real and imaginary ones.
Why did the vector cross the road?
It wanted to be normal.

Re: Real and Imaginary Numbers
Thanks, mathsy. Example: Hyperreals are an extension of Reals that include infinites and infinitesimals.
And, yes, complex numbers include imaginary, real and combinations of imaginary and real. I should write a page, hey?
