Havnt proofs been proved wrong before? some where they where held as true for many many years?

Okay, so I think I figured out another way to explain it and make it a bit more understandable.

So, we start with 0.999... right? Then we add 0.111...

So we have this :

  0.999...

+0.111...

And that is equal to 1.111... (think of it as an infinitely repeating process, where you first add 0.9 and 0.1, then 0.09 and 0.01, 0.009+0.001, 0.0009+0.0001 etc.)

Then we subtract the samething we added, 0.111....

now, obviously, 1.111.... - 0.111... = 1 and since 0.999...+0.111=1.111... then 0.999... = 1

 

Can't be bothered to formulate this into a normally formulated proof, this is more as an additional explanation to make it easier to understand.

Honestly, I still think the 1/3 method is the best and simplest way to prove it, don't bother searching for lots of different explanations, it's all on the Wiki page anyway ^^.
