Proof that 0.999 = 1

See, the proof here is of 0.999.......= 1 and not 0.999 = 1

so if a = 0.999.....

then 10a = 9.9999.........or 9.9......

9a = 9.9... - 0.9... = 9

So, a = 1

Didnt see the 1b - 0.99 x 1b part :ashamed:

Although Im happy with even 1b x (1-0.99) = 10 mil :D
 
What the hell is going on here... this is like math kids having orgy (or gangwar, depending how you look at it) here...

Now I've to go and drink some REALLY strong coffee to get rid of this headache... :P

0.999 is not equal to 1. As the article mentions, the method is employed in schools to convert infinite decimals (i.e. irrational numbers) to finite decimals for calculation ease. In Real Numbers, there are basically infinite numbers between any two numbers.

Here is another conversion:

a = 0.888888 - 1

10a=8.88888 - 2

subtracting 2 from 1

9a=8

a=8/9

now look for fraction 8/9 in calculator it is 088888...something , but 088888 is not equal to 8/9

when you take a=0.99999

the final fraction comes out to 9/9 =1, hence confusion 0.99999 =1
 
1/3 = 0.333....

1/3 x 3 = 1
0.333... x 3 = 0.999...

But I am not ready to believe.... maybe I need faith :P

And Maths is beyond calculators... Calculator is just a machine which is always finite and can never calculate something like this....

OMG! its not about equating 0.999=1, it is about whether 0.999..to infinty or say bar = 1

Please don't confuse the two! Its quite obvious that 0.999 is not equal to 1
 
Already tired of doing maths for tomorrow's exam and when I open TE what is See is maths Again !!!

how boring !!!

People find out any nonsense formulas and proofs which common man can't understand so they are made theorems and properties

IN this way I will prove that 100 = 1 (since zero has no value )

Alternate method multiply both sides by 0 . Therefore 100=1 (since LHS = RHS)

And now this will become a property because nobody can understand it

lolzzzzzz !!!! confused ??

Apparently, you need to go back to middle school too.
 
check out this guys

prove that

100=6

proof

let a=b

multiply both sides by 94.......94a=94b

(100-6)a=(100-6)b

100a-6a=100b-6b

100a-100b=6a-6b

100(a-b)=6(a-b)

cancel (a-b) on both sides

therefore 100=6 hence proved...

hows that....:cool2::cool2:

100(a-b)=6(a-b)

cancel (a-b) on both sides

therefore 100=6 hence proved...

Since a = b are equal you cannot multiply by (a - b) = 0 and say they r equal by cancelling it

100(a-b)=6(a-b)

100 x 0 = 6 x 0

0 = 0

100 != 6 :P
