[Math] Prove 0.999...=1 (Amaze your friends!)

[Xel]

NOTICE: A good knownledge of maths (basic) is needed to understand this thread.

I say that
0.999...= 1

in this thread it means same as
___
0.999 = 1

I can prove it!

First of all |-marks means that both sides of the problem are changed,
so X=5 |+5 means that +5 is added to both sides.

0.999... means that the number goes on like this
0.99999999999999999999999999999999999999999999999999...

REASON 1:
1/3=0.333.... |*3

=> 3/3=0.999...
=> 1=0.999...

REASON 2:

X=0.999... |*10

=> 10x=9.999... |-X
=> 9x=9 |:9
=> x=1
=> 0.999...=1

Same as:

10X=9.999...
-X=0.999...
_____________
= 9X = 9 |:9

=> X=1
=> 1=0.999...

REASON 3:

In math, between 2 numbers there will always be a one number
for example:

between 1 and 2 there is number 1
(1 + 1 = 2 )
between 1.5 and 1.6 there is number 0.1
(1.5 + 0.1 = 1.6)
between 1.555... and 1.666... there is number 0,111...
(1.555... + 0,111... = 1.666...)

But whats between 0.999... and 1 then?
NOTHING.

Thats why:
1-0.999... = 0
and


0.999...=1




Prove me wrong!


BONUS

1+1=1


Something is actually wrong in this thing. Can you solve what?
a=b |* a
a^2=ab |-b^2
a^2-b^2=ab-b^2
(a+b)(a-b)=b(a-b) |: (a-b)
a+b=b
1+1=1
1=2

Ok. I'll tell yuo what's between 0.999 and 1;
0.9991
0.9992
0.9993
0.9994
0.9995
0.9996
0.9997
0.9998
0.9999
0.99911
0.99912
0.99913
0.99914
0.99915
0.99916
0.99917
0.99918
0.99919
--- You get the picture...
Your explanations are extremely palavorous (you include things that don't need to be included, this is all much easier than you're attempting to portray.)

On the basis of 0.999 recurring, then yeah you're right. But not 0.999
You're explanations are extremely palavorous (you include things that don't need to be included, this is all much easier than you're attempting to portray.) Grade 4 stuff.

0.999... means that the number 9 continues repeating on forever (like 0.9999999999999... you know?).
So there are no numbers like 0.99918 between.

Wasn't this a blizzard april fools joke a while back there a whole wiki about it

[Xel]

Could be, never seen it tho.

0.999¯

No... '0.999...' doesn't meen 0.999 recurring.
*0.999... meens 0.999 elipse, aka something included although not said - most likely a cliff hanger, generally used for suspense in literature. you saying '0.999...' signifies an expectation for the reader to understand by now, or rather for them to follow up on what you're saying.
0.999 with a small dot above the 9 is recurring. You're incoherant at times Xel

[Dragonshadow]

Overscore also means recurring.

[McGoogle]

ok first of all you're completely wrong.
In reason 3 inbetween 0.999... and 1 there is 0.000...01.
Also you wrong just accept it.

[Xel]

0.000...01 is not possible... As far as I know.

0.000... means (or atleast in this thread omg ) that the zeroes keep on coming infinitely.
That would mean a number like Infine + 1 which does not exist.

[McGoogle]

ok so now you are making the number infinity? By adding the '...' which you say makes your number go on indifinately and by making them carry on infinately you are saying that the number 1 and all above it are bigger than infinity?

[Xel]

:O? If you saw my first message, it was a missclick. (I was reforming my words )

[McGoogle]

where was a misclick

[~sInX]

Ouch; Xel's post = raped by McGoogle.
Nice post edit Xel Next time get it right initially.

Edit:

Sorry i just had to say this;

BONUS

1+1=1


Something is actually wrong in this thing. Can you solve what?
a=b |* a
a^2=ab |-b^2
a^2-b^2=ab-b^2
(a+b)(a-b)=b(a-b) |: (a-b)
a+b=b
1+1=1
1=2

Dude. WTF?! Either you're fail beyond belief or you were drunk when you posted this, which i doubt, after your protests to me on msn to stop posting here.
1 DOESN'T = 2.
Your lil' a^2=ab |-b^2 doesn't make sense. Oh and 1+1 = 2. NOT 1. LMAO. If you're trying to make yourself look smart m8, stop digging the hole.
Mods, this isn't a flame;
1. I'm saying what every1 else is thinking
2. There are a lot of kids who use this website and look up to elite members. If they get into their head that 1+1=1 then **** knows how their KS2 will go...

[McGoogle]

in your main thing
a=?
b=?
plz state because if they both =1 like yr implying at the end than the same letter would be used throughout...fails
