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

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

I hate people who hate people.

most people make mistakes, butt not me!

why is it when you are writing something important you run out of spa

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.

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?
