A mathematician, to whom this is a whole new topic, would start by
asking you what you mean by "more".  Without that, they could not

  So, what do you mean by "more" when applied to
sets like C and R?

Proper subsets have less elements than their supersets.

Let's see if Chris is using that definition.  I think he's cleverer than
you so he will probably want to be able to say that {1,2,3} has "more"
elements than {4,5}.

 I was just thinking that there seems to be "more" reals than natural numbers. Every natural number is a real, but not all reals are natural numbers.
 So, wrt the complex. Well... Every complex number has a x, or real component. However, not every real has a y, or imaginary component...

To refine it... NO Real has a y, or imaginary component. The complex numbers do. So, can be thought of as being more dense? Or space filling a 2d plane? Reals are 1d. Is 2d "denser" than 1d? Or is that the wrong way to think about it? Thanks.

 Fair enough? Or still crap? ;^o
