The first one I ever saw:

The following statement is true:

The previous statement is false.

You are what you eat.

a=b
a+a=a+b
2a=a+b
2a-2b=a+b-2b
2(a-b)=a+b-2b
2(a-b)=a-b
2=1

This statement is false!

That all doesn't work out becouse a minus b is zero. 2(a-b) = 0 = a-b = 0.

0 = 0

whats the problem? =P

a = b
1 = 1

a+a = a+b
1+1 = 1+1

2a = a+b
(2*1) = 1+1

2a - 2b = a + b - 2b
(2*1) - (2*1) = 1 + 1 - (1*2)

2(a-b) = a + b - 2b
(2*1) - (2*1) = 1 + 1 - (2*1)

2(a-b) = a - b
(2*1) - (2*1) = 1 - 1
2 - 2 = 1 - 1
0 = 0

Sorry, it works out. You just twisted the equation around a lot and somehow confused yourself. a = b at the start so for all intents and purposes I think we could've just got rid of b and used a. Any number subtracted by itself is zero (feel free to prove me wrong somehow). I wonder if there are actually any mathematical paradoxes? I'd like to say no, but I am not exactly a genius mathematician. Would be interesting to see.

...uh...what?

ah, I thought he had posted it right....

here it is..

a=b

multiply by b

ab = b^2

subtract a^2 (thats a-squared)

ab-a^2 = b^2 - a^2

factor

a(b-a) = (a+b)(a-b)

the (a-b) on both sides cancel each other out.

a = (a+b)

1 = 2

there =P

The (a-b) on which two sides?

(b-a) is NOT EQUAL TO (a-b)

actually it is if a=b

oh, and dont blame me ... I didn't come up with it.

It isn't a paradox Kaniaz allso explained it correctly. Most of those 2=1 paradoxes work by an error that occurs if you use a zero.

A x 3216 = A x 0.332, just aslong as A is zero, it doens't mean 3216 = 0.332

bah i think i did it wrong too. oh well.

Yeh, its all in the zero =P

now can you figure out whats wrong with the 0.99999999999 repeated = 1? =P

19 / 0

DIVIDE BY ZERO

OH SHI-

*world explodes*

Go back in time and kill your grandma

Then you'll never be born, then never would be able to kill your grandma

Then she would live then you would be born then kill her

But you would never be born and I could go on for hours

Go back in time and do whatever it was you wanted to do, then you won't have a reason for having gone in the first place. You really don't need to get grandma caught all up in this.

This sentence does not make sense.

Red. Blue. Noooooo!

you are your own grand pa

Fixed.

Exactly. Even without killing a parent/grandparent/great great great [...] grandparent, you could just go back in time to do [whatever], but seeing the event is prevented/done, you had no reason to have created the time machine in the first place in the present; In that case, there would be no reason for you to have made the time machine. It's an evil loop/paradox/vicious cycle/something.

0.9999999999<strike>9</strike> = 1[/b]

I [s]&#39;d the last 9. Usually you put a slash through it to show it repeats, but I can&#39;t exactly put a slash through another character on the computer, can I?
Either way, 0.99 = 1 because of rounding. Duh?

now can you figure out whats wrong with the 0.99999999999 repeated = 1? =P[/b]

Nothing? It&#39;s true.

mmm another dox

don&#39;t believe anything you read on the internet.
