X*(X) = X*(Y)Right.

X^2 - Y^2 = XY - Y^2Right. 0 = 0

(X+Y)*(X-Y) = X*(X-Y)Right. 0 = 0 again.

(X+Y) = XX + X = X

2*X = 1*X

If X = Y = 0, yes.

2 = 1Wrong. You can't divide by 0.

In this series, the negative terms are increasing twice as fast as the positive terms.

In this series, the negative and positive terms are increasing at the same pace. Since they are infinite, the series are thus not equal - they converge to a different value.

The problem isn't that x = 0. If it continued as written, every group of 3 terms ( (1,2,3) (4,5,6) , etc...) would sum to something strictly positive.

The problem is the exact definition of 'x'. Try to expand out the series for x just a little bit further and still get the identity x = x/2 to work out after adding the brackets. I think that you're going to have some trouble.

x = 1 - 1/2 - 1/4 + 1/3 - 1/6 - 1/8 + 1/5 - 1/10

then

x = 1 - 1/2 + 1/3 - 1/4 + 1/5 -

as that's what you do in your substitution step. But those two infinite sums are totally different. Rearranging numbers in an infinite sum is not allowed without very careful consideration. It be like saying:

1 + 1/2 + 1/3 + 1/4 + 1/5 + 1/6 + 1/7 - 1/2 + 1/8 + 1/9 + 1/10 + 1/11 + 1/12 + 1/13 + 1/14 - 1/3 + 1/15...

was the same as 1 + 1/2 - 1/2 + 1/3 - 1/3 + 1/4 - 1/4....

The idea is the same - your are promoting the subtractions well before they would ever happen. Before you ever reached the -1/4, you would have already added up between 1/1 to 1/28 and only subtracted out 1/1 to 1/4, leaving a pretty significant sum. In fact, the sum should become roughly sum 1 + sum(1/(k+1) to 1/n) s.t. k = n/7 using integer division (rough meaning it's 10PM here and I'd rather go to bed than be precise). In fact, I think this sum goes to infinity, while the other goes to 1!

This isn't using divisions by zero. This particular "proof" relies on the fact that rearranging the terms of a nonabsolutely convergent series does not necessarily give the same sum. In fact, such a series can be transformed into a series with any given sum simply by rearranging the terms.## Re:Sure! (Score:2, Informative)

1) The series diverges, and the algebraic manipulations of its "value" were meaningless.

2) The series converges to 0, and there was division by 0.

3) This particular series doesn't follow that pattern past the first few terms, and the equation 2x=x doesn't follow, even if it does converge.

In any case, Riemann's rearrangement result is unnecessary.
