Are imaginary numbers real?

Question

I thinks they R

Answer 1

Well, yes, imaginary numbers exist, which, from the way you are asking your question, is how you are interpreting the word "real". However, mathematics has its own definition of "real" numbers, and by that definition imaginary numbers are not real.

Loosely speaking, the real numbers are the numbers on the number line, i.e. the rational numbers like 1 and 2/3, along with the irrational numbers like π and √2. The imaginary numbers, however, are an extension of the numbering system and do not sit on the number line.

So, to answer your question, it all depends on what definition you use.

Answer 2

actually, people say that numbers like square root -2, 1/0, are imaginary numbers is because they can't prove that these numbers are real. so, in my opinion these numbers are real, but it's just that someone hasn't come up with a theory prove it...

Answer 3

They're as 'real' as the irrationals. They (like the irrationals and the transcendentals) are just elements having different (and, under some conditions, quite useful) characteristics.

Then there are the 'hyper-complex' numbers (or 'quaternions') first developed by Cayley.................☺
