0 = 0

(1 - 1) + (1 - 1) + (1 - 1) + ... = 0
1 - 1 + 1 - 1 + 1 - 1 + ... = 0

Problem mathfags?

>> No.4711627

Not with poorly formed mathematics, no no problem at all.

>> No.4711644

Yes there is a problem, you're missing a -1 in the second to last step.
But that was good try indeed, regards.

It's an infinite sequence, there's no end.

So, 1 plus a series of zero is suddenly zero?

Logically arrived from a true statement:
0 + 0 + 0 + 0 + ... = 0
Unless there's a flaw in the logical steps. It would be nice for you to point out which.

0 + 0 + 0 + 0 + ... does not converge to 0?

>> No.4711730

>>4711715
it does

problem comes when associativity is assumed.

(1 - 1) + (1 - 1) + (1 - 1) + ... = 0
1 - 1 + 1 - 1 + 1 - 1 + ... = 0
1 + (-1 + 1) + (-1 + 1) + ... = 0

not allowed unless absolute convergence

It sure does, but 1 + (0) + (0)... does not.

Prove this OP. I'll believe you when you've summed an infinite number of zeros in your head.

Suppose the series converges to a real number S.

1 - S = \left( 1 - 1 \right) + \left( 1 - 1 \right) + left( 1 - 1 \right) + \left( 1 - 1 \right) + \ldots
1-S = S

Shouldn't

1 − S = 1 − (1 − 1) − (1 − 1) − (1 − 1) − (1 − 1) −...

be

1 − S = 1 − (1 − 1) + (1 − 1) + (1 − 1) + (1 − 1) +...

?

>> No.4711867

>>4711852
You have to subtract each term in the series when you subtract S. So there is a minus before each term. Then you just distribute through the negative and rearrange the parentheses.
