From the early definition of the rational numbers, we can simply extend their concept, but with infinite integers, so the real number definition becomes as a ratio of two finite or infinite coprime integers
And this definition doesn't count (zero, one, infinity) as real numbers except by CONVENTION

In my opinion, the proof is straight foreword from the definition only > > -- > Glen > > Regards
