Does .9-repeating equal 1?

Given the choice I'd say the general public would say "screw this" and legislate pi = 3.

3.14 . I could go to 3.10. Ok. make it 3. Can't go any lower.

You don't really want to challenge me in real analysis.

I'll epsilon-delta your ass six ways from sunday...

Krazy,

0.9 does not equal 1
0.99 does not equal 1
0.999 does not equal 1
0.9999 does not equal 1

etc.

At what number of 9s does this progression become equal to 1?

[Jaguar]

Is that supposed to be an argument for something?

Obviously, you need an infinite number of nines. There is no finite number of nines for which it's an equality.

Does that change that it's from grammar school? Keep on point, zoics-dog. Or are you just pissing for some general challenge? If so, come up with something interesting, I'll oblige.

At the point where you put the little bar over the 9.

Are you an idiot?

Nah, just pissing about in general. Anyhow, this thread is just a convenient excuse to insult the ignorant.

Here's a clever problem I came across the other day:

I have a punch which is very special. If I center it over a point then it removes all the points in the real plane (RXR) which are an irrational distance away from the original point.

How many punches do I need in order to remove the whole real plane?

This is a repeat of a old thread.

I at first thought it was necromancy.

It isn't as fun.

Get smarter. That one only took me 4-5 minutes

Spoiler:

Obviously, you need at least 3. But (0,0), (1,1), and (a,a) work where a is any transcendental.

Oh, and I'd like to challenge you in real analysis .
