Is this true??

The problem with X=.99999999...

When minus'ing the X,  frim both side, you minus X,

plug in X on BOTH sides,

10(.99999....) - .999999 = 9.999999 - .9999999

it then comes out correctly, it is the same instance as if a=b

and you divide by (a-b) to make 1=0.

It is a trick of the variables and when correctly put with numbers instead of letters makes everything correct.

Re: Is this true??

i dont quite understand what you're doing here to get 1=0?

Recurring numbers have several rules to them.

Re: Is this true??

If a = b, then a - b = 0, and division by zero is not valid here.

Re: Is this true??

I do wanna argue that the approach of 10*0.999... thing does imply the last "9" equals the second last "9". And sorry I don't quite agree with the so-called rules designed to cover a bunch of paradoxies created by the original concept.

Re: Is this true??

And the proof does imply ∞+1=∞ regarding how "many" "9"s

Paradox?  I'm sorry, but what paradox?  The only thing you have said so far is that stating .999... = 1 requires a guess.


"In the real world, this would be a problem.  But in mathematics, we can just define a place where this problem doesn't exist.  So we'll go ahead and do that now..."

Great point, since you finally keep it in mind. I'll explore the other paradoxes soon. Wait for me
