.9(repeating) = 1

[Niosis]

Hello to you. I'm Niosis, I play CS, you don't know me or care to know me. I know Ova(god rest his soul).

The statement .9(repeating) = 1 makes absolutely no sense to me. I've reviewed the wikipedia article on it and I've still been baffled as to how anyone accepts .9(repeating) to be equal to 1.

For starters, .9 repeating is a DECIMAL, a decimal is PART of a whole number by definition, so how can a decimal equal a whole number?

Secondly, .9(repeating) is infinite, it's constantly growing, never stopping. 1 is a whole number. It is not infinite, nor is it constantly growing.

How can these 2 things be equal? I understand you plug them into a few crap formulas that don't accomodate infinitesmals and then say "LOL LOOK IT EQUALZ 1", but when you look at the two numbers seperately, that really makes no sense.

Oh shi-


Oh god, I thought we had this debate before

Get the **** out, I`m sick of this shit.

 

[carlyftwbaby]

I stand behind you, .9 (repeating) definately does not = 1.
good call.

Admins, feel free to close the topic now.

Before this gets closed, because my spider sense tells me that the end is near, the way it works is .999 repeaing to infinity has to be treated as a limit, not a finite number, and in that respect, the math works. If you only have, say, .999, then it doesn't work. Arguments ensue because, well, because that's what people in online forums do.

This argument is basically like this:

Which math is it that works?

Are you saying that .9(repeating) does in fact equal 1 or not?

Hopefully the admins will avoid the close seeing as how the last thread was started by someone acting like an ass and it didn't really get anywhere.

Another thing that's puzzling is how everyone in the last thread said that .9(repeating) does not equal 1, but the wiki article seems to claim that it's common knowledge that the reverse is true.

 

[Hazar]

it is, because math says so:

x = .9999etc
10x = 9.9999etc

10x - x = 9
9x = 9
x = 1

 

[Stigmata]

Anyone who doesn't agree that 0.999... = 1 needs to take a pre-calculus class.

 

[Krynn72]

it is, because math says so:

x = .9999etc
10x = 9.9999etc

10x - x = 9
9x = 9
x = 1

I dont get it. Why are you randomly subracting x from one side? Why are you rounding 9.99 repeating to 9?

EDIT: Nevermind

 

[Pauly]

Basically it goes like this-

1/3 (one third) = .33333333333333333333333... (repeating)
2/3 (two thirds) = .66666666666666666666666666...(repeating)
3/3 (Three thirds) = 1
Or does it? Some people say that 3/3 continues to .999999999999999999...(repeating)

But 3/3 = to one! Therefore .9 repeating = 1.
LOLOLOL


Yea thats what people have told me before, I dont buy it till I have reasonable sources...

 

[Smoke]

No. Do NOT start this shit again.

CEASE.

 

[Adabiviak]

Do a search on Wikipedia or Google - you'll find pretty good explanations there if you stay away from forum hits. Try this

 

[Krynn72]

it is, because math says so:

x = .9999etc
10x = 9.9999etc

10x - x = 9
9x = 9
x = 1

Wait a second, does that necessarily mean its actually equal? Because that last line is the same as saying .999... = 1, so couldnt that be an inequality?

EDIT: ****, its too late for maths. Im gunna believe that .999 repeating cant equal one because if it did we would call it one. There, logical enough for me, ima outta here!

I've doubted .3(repeating) = 1/3 since the very, begining when I was told that, again because of the infinity thing.

Makes sense to me.

 

[Geogaddi]

I apologize, my friend is a little slow.

Also maths

 

[carlyftwbaby]

****ing .9(repeating) does NOT = 1.

RRRRRRDURHRHness.

 

[Krynn72]

F*ck maths.

x = Mountain Dew
Dr.Pepper(x) = Dr.Pepper(Mountain dew)
Dr.Pepper(x) - x = Dr.Pepper(Mountain dew) - x
Sierra Mist = Dr. Pepper

See, by using a simple analogy, i have proven this equation wrong.

Whatever do you mean? I can assure you I'm not anything but sincere.

[theotherguy]

you ought to take calculus or pre-cal.

You want me to explain without equations? I will try.

.9999... is a limit, it is not a number. Limits represent infinite division/multiplication onto a single point.

.999..., continuing in a function into infinity, would converge on 1. Since .999... asymtopes at 1, the difference between 1 and .999... is infinitely small (this is what limits do, they represent what a function does at infinity).

Thus, because the limit .999... converges on 1, it equals 1, just as a limit converging on infinity does not exist or a limit of 1/x =zero.

 

[Stigmata]

People without calc/precalc education trying to convince everyone that 0.999 != 1 are like people without a physics education trying to convince everyone that a plane will take off when on a treadmill.

We should've left it at Macarena.

 

[Jintor]

W00t, in Stigmata's eyes I'm finally ready to understand .999... = 1!

 

[Tollbooth Willie]

Indeed.
