9x is 9*0.999... that is supposed to equal 8.999...
in your original statement you put 9x=9
you are telling me this is not number shuffling, you posted a statement with math to show your reasoning and the math was wrong because you changed the rules of multiplication.

NO I DIDN'T, I NEVER EVER MULTIPLIED TO GET THAT... how hard is that to understand, you are looking at them as seperate statements which they are not, they are equivalent statements from one line to the next.

Also, 8.999... = 9 anyway.

what do you mean you never multiplied???

x = 0.9999...
10x = 9.9999... 10*0.999... =9.999...
10x - x = 9.9999... - 0.9999... 10*0.999...-0.999... = 9
9x = 9
x = 1.


those are multiplication so why is 9x any different

and 8.999... only equals 9 if you go along with the assumption that 0.999 = 1 which is what you were supposed to be showing proof of when you posted the statement itself.


The whole bases of what you are talking about with real numbers is working with the assumption that 0.999... = 1
