The following table, which is countable (google), includes all pos rationals and reals. The reals are a subset of the rationals if you define: Real: m/100000........., all m Note: Left column and Top row are endless, \begin{matrix} &1 & 2 & 3 & 4 & . & . &. \\ 1 &\frac{1}{1} & \frac{1}{2} & \frac{1}{3} &\frac{1}{4} & . & . &. \\ 2 & \frac{2}{1} & \frac{2}{2} & \frac{2}{3} & \frac{2}{4} & .&. &. \\ 3 & \frac{3}{1}& \frac{3}{2} & \frac{3}{3} &\frac{3}{4} &. & . &. \\ 4 & \frac{4}{1} &\frac{4}{2} &\frac{4}{3} & \frac{4}{4} &. &. &. \\ . &. &. & . & . & . & . & .\\ .&. &. & . & . & . & . &. \\ . &. & . & . & .& . & . & . \end{matrix}\\ 0 assumed included.

$\pi \in \mathbb{R}$ $\pi \not \in \mathbb{Q}$ $\therefore \mathbb{R} \not \subset \mathbb{Q}$

$\displaystyle \pi$ $\displaystyle \equiv$ 3 "+ " 1415926....../1000000....... That's awkward and requires refinement: my original version was: The real numbers in [0,1] are a subset of the rational numbers in [0,1]. From table. Real numbers in [0,1] = m/1000......... , all m In that case, a real number is N.r which is still countable: N is a subset of the rationals and so is r.

I doubt zylo will accept your proof. He simply assumes again that an infinite set has the same cardinality as any other infinite set. There is no doubt that he has described an infinite set that includes all rationals. In fact, it includes every possible decimal representation of every rational number. He still has not shown how he matches each real to one of these representations. Obviously, he will have no difficulty matching a unique rational to one of those representations. But he neglects to show that the irrationals match up with the remaining representations. Instead he implicitly relies on his assumption. Last edited by JeffM1; May 18th, 2018 at 10:32 AM.

It's my opinion you just want attention. Have fun.

I recommend closing this thread and stopping Zylo from creating more like it. I can't see any value at all in rehashing this nonsense again.
