You must keep like terms!!!Code: Select all
9x = 9.999999... - .9999999...
9x - .999999... = 9
Anyways, in your theory, it should be,
9.000...1x = 9

In mathematics, the repeating decimal 0.999... (sometimes written with more or fewer 9s before the final ellipsis, or as 0.9, , 0.(9)) denotes a real number that can be shown to be the number one. In other words, the symbols "0.999..." and "1" represent the same number. Proofs of this equality have been formulated with varying degrees of mathematical rigor, taking into account preferred development of the real numbers, background assumptions, historical context, and target audience.

a and b are equal and are both non zero values
so if a = b then
aa = ab
or
a² = ab
a² - b² = ab - b² because it's still balanced
so (a-b)(a+b) = b(a-b) (factorize)
divide out (a-b) leaves us with a+b = b and since a = b, b+b = b
so 2b = b
divide by b
2 = 1
Code: Select all
1=1
1² = 1*1
1² - 1² = 1*1 - 1² still balanced
(1-1)*(1+1) = 1*(1-1) so basically 0=0 so far so it makes sense
since the next step is divide out (a-b) we have run into a problem, because it will always be zero.
continuing...
(1+1) = 1
2 = 1

clearly you didnt read what it was in the link...i pointed out that the logic you used has fallacies, and that link shows whyrokit boy wrote: 1) i have no idea why you pointed it out that i got it from the internet. wasn't it so obvious?
