The "common sense" proof

[RakuraiTenjin]

What you're saying is that 0.99..../1 = 0.9...

none of those fractions hit 0.9recurring... the sequence you describe will approach it, but won't ever equal it



hehe, until you study maths Rakurai stay the hell away , I can prove my result and you can't, and that's what matters

You don't even realize or comprehend how you're wrong! I can't see why!

.999... repeats with 9's forever, it approaches but never reaches one. It is practical to round .999... to one for use in real situations, but it is not one itself.

 

[15357]

Look, 0.9 recurring is a number. Let a number = x

0.99999... = x
1 = x
0.9 = x
1.888.... = x
2 = x

etc

Therefore, 0.9999... equals x, and as stated, x = 1. It also equals 0.9999.... and 1.88888... and 2 and 4 and 42 and 66 and 5934.

Therefore, they all equal the same thing, and cancel each other out.
Therefore, maths does not exist.

Therefore, you are all noobs.

SIR YES SIR! MATHS DOES NOT EXIST! 2 + 2 = 5. INGSOC.


Ignorance is Strength.

Really, IT IS ESSENTIAL THAT A NUMBER BE REPRESENTED AS A FRACTION. IF ANYONE CAN GIVE ME A CORRECT ONE, PLEASE?

I love you, but we can't have babies anymore.

 

[Ludah]

You're incorrect, it doesn't 'approach' anything. Numbers can't approach anything, by their nature they are constant. Does 0.3 recurring approach 1/3? No, because it is 1/3

Then there you have it. It never equals 1. Ta.

 

[15357]

1/3 = 3/9 = 0.33333...

therfore 5/9 = 0.5555...

And 9/9 = 0.99999..... = 1.


NUMBERS ARE SUPPOSED TO ****ING BE POSSIBLE TO REPRESENT AS FRACTIONS! YOU ARE ALL NOOBS. 0.999... = 1

 

[jondy]

Then there you have it. It never reaches 1. Ta.

You misunderstand me, it never 'reaches' anything. It's a fixed value.

Here's a bunch of proofs

 

[sinkoman]

No, it has a numerical value constantly approaching 1, but will never reach it. It simply goes on for infinity.

It's like how a number to the power of 0 is 1, instead of 0.

Don't question the principal, it just IS.

 

[_Z_Ryuken]

What you're saying is that 0.99..../1 = 0.9...
none of those fractions hit 0.9recurring... the sequence you describe will approach it, but won't ever equal it

I am still wondering why you are telling me this.

 

[15357]

I'm gonna say this again. Numbers can be, and are supposed to be able to be represented as fractions. Until anyone can provide a fraction for 0.999... that does not equal 1, 0.999... is one. The end.

 

[jondy]

I am still wondering why you are telling me this.

Because you believe (forgive me if I'm wrong, maybe I misunderstood you) that 0.99... approaches a value, when it doesn't, it has a fixed point on the number line

 

[RakuraiTenjin]

1/3 = 3/9 = 0.33333...

therfore 5/9 = 0.5555...

And 9/9 = 0.99999..... = 1.


NUMBERS ARE SUPPOSED TO ****ING BE POSSIBLE TO REPRESENT AS FRACTIONS! YOU ARE ALL NOOBS. 0.999... = 1

It's not one 9's just repeat forever it never reaches one

 

[sinkoman]

While I do agree that .999 is equal to one, your entire argument right there is a fallacy.

Just leave it at, it just is. X^0 is 1. God knows why, but it just IS!

 

[_Z_Ryuken]

Because you believe (forgive me if I'm wrong, maybe I misunderstood you) that 0.99... approaches a value, when it doesn't, it has a fixed point on the number line

You must have me qonfused with someone else.

 

[15357]

But I can provide a fraction for 0.9999...., which is 9/9.

It's not one 9's just repeat forever it never reaches one

Where is thy fraction?

 

[jondy]

You must have me qonfused with someone else.

fair'nuf

 

[_Z_Ryuken]

While I do agree that .999 is equal to one, your entire argument right there is a fallacy.

.999 cannot equal one because that would be inaccurate. Far too many people rely on extremely precise measurements.
I for one need to calibrate my car's throttle position sensor to within 0.01 volts or it is not going to work efficiently. Leaving it at .49 instead of .5 just because the value is very close just does not cut it in the real world. This is a very mild example.
I understand though, if I had a multimeter that could measure to 30 decimal places, and I read .499999999999999999999999999999 that would be sufficient as the difference is negligible for that application, but to say the ultimate static value is .5 would be for all intents and purposes, inaccurate.

9999/10000

If 10000/10000 = 1
9999/10000 = .9999

.4999 isn't the same thing.

If you need a really precise measurement, then you'll be careful enough with your formulae and calculations that you won't end up with a repeating decimal.

Saying that a repeating decimal needs to be more accurate is like saying a turd is too tasty.

 

[kirovman]

What's all the debate for? Didn't everyone learn this in High School maths?

 

[bodhi]

let me just say i hate maths for stupid ****ing things like this. ive just about rendered my opinion null and void with that but it seems that some lazy prick decided he'd make his life easier by saying 0.9999... recurring would equal 1, and that since then everyones followed suit cos it fits neatly with everything else and as a explanation. i dont nessecarily think that makes it true though, in fact i think its a load of bollocks

NUMBERS ARE SUPPOSED TO ****ING BE POSSIBLE TO REPRESENT AS FRACTIONS!

supposed to be?....according to who? the dickhead who started this mess by trying to put everything into its little box? in its place? in some uniform order?......remember, you are not your ****ing khakis

BAN MATHS and go play HL2 before we all spill our juice.

edit: i just know im gona get quoted and embarrassed for my stupidity but sod it (like i said, i dont like and am not particularly good at maths)

 

[Naudian]

I agree with both sides of this stupid argument...weird...

That's exactly it.

Just as a number to the power of 0 is 1. Nobody knows ****ing WHY, just some douchebag that pioneered maths decided things would be that way.

 

[_Z_Ryuken]

It's exactly the same because we are just rounding off numbers.
I agree if someone needs a precise measurement, they will get one. They won't settle for a rounding off. It is simply innacurate in certain cases.
In other cases it's absolutely fine to say 0.999999 = 1, or .499999999 = .5. It's all the same concept. 1 doesn't have any special properties. 3489.983645 can = 3490 for all I care.

What everyone needs to realize is that it can't work like that in all cases, but it can in others.

Everyone is right.

Just as a number to the power of 0 is 1. Nobody knows ****ing WHY, just some douchebag that pioneered maths decided things would be that way.

I think it should be 0. o_o

 

[kirovman]

In real life, we never measure things to infinite decimal places anyway, due to inherent uncertainty in everything.

This is simply a purely mathematical concept.

Kiss my ass. How many threads are you going to create on this topic?

Okay, this isn't something were everyone can be right and we can all walk away happy chappys.

This is Math.

Decimal numbers are just representations, and because it's a base ten counting system has limits to itself.

Logically speaking, you're telling me two numbers with a difference that is infinitely small (0) are different.

Next you'll argue that 1/2 =/= 0.5 cause you have a 1 and a 2, where the hell did the 5 come in?

Seriously, this is a math logic step, if you don't understand it, accept it.

According to mathmeticians.

 

[15357]

9999/10000

If 10000/10000 = 1
9999/10000 = .9999

0.9990 =/= 0.999....

 

[Sulkdodds]

0.99999... = 1
Maths != common sense

Maths has NOTHING whatsoever to do with common sense and intuition. Cast aside anything you 'think' you know...

This is simply a purely mathematical concept.

BAN MATHS

As long as you cannot prove it using accepted axioms, we may be right.

I know only one side can be right, but since neither can prove it conclusively, leave it to real mathematicians.

I'll fix this like all arguments of this type are fixed;

In "Applied" Maths, 0.999... = 1
In "Pure" Maths, 0.999... != 1

Problem solved. Please pick a nice reward for me.. (Perhaps some cool knicknack from one of those online surplus/tactical garb stores.. I hear surefire lights are going cheap! thigh holsters are cool too... I dont have a gun, but the holsters are cool on their own anyway!)

[Raeven0]

...

Y'all do know that there are NUMEROUS mathematical proofs that point nine recurring equals one, right?

If you can't show how ALL of them are wrong, I suggest you stfu.

Point nine recurring is a single number. It DOES NOT "approach" anything because it is ONE NUMBER with ONE VALUE. If you attempted to transcribe point nine recurring on paper, THEN the number on your paper would approach point nine recurring AND one with each additional nine; but we are talking about THE NUMBER ITSELF, NOT the number as you try to write it out.

For your further edification, a series can have only one limit; point nine recurring, as it is written out, approaches both point nine recurring and one; therefore, point nine recurring must equal one, since they are both limits to the series.

 

[TheSomeone]

.9999... goes on forever with 9's, it never reaches one. You can only get to 1 by rounding.

It continues on with 9's forever. Forever and ever, for eons and never stops- it never reaches one.

stfu you troll, we all know you're doing that on purpose. You've been spewing the same shit over and over its becoming obvious, go home.

I'll fix this like all arguments of this type are fixed;

In "Applied" Maths, 0.999... = 1

FFS
DID YOU ALL FAIL REMEDIAL ALGEBRA?

What math is unpure about this????

x = 0.999...

multiply both sides by 10

10x = 9.999...

10x - x = 9.999... -0.999... (subtracting the same thing from both sides)


9x = 9

so

x = 1.

im sure there are NUMEROUS mathimatical proofs the point to nine recurring doesnt equal one, right?
