Let me say first of all that there is no real proof for the statement 1 + 1 = 3. You cannot use correct mathematics to prove an incorrect statement. However, there are a couple of cutesie "proofs" of stuff like this, and you can use them to "prove" anything you want. The most famous example is the "proof" that 1 = 0, and once you prove anything that isn't true, you can prove ANYTHING else. You could prove that the moon is made of green cheese. You could prove that 5 = 8. You could prove that I'm your father. And yes, you could also prove that 1+1 = 3. That's because the statement p => q is always true when p is false. So that's the deal. Let x=y. Then x - y + y = y x - y + y y --------- = --- x-y x-y y y 1 + --- = --- x-y x-y 1 = 0 Now we know that 1 = 1, so add the following three equations together: 1 = 0 1 = 1 1 = 1 On the right is 1+1, and on the left is 3 ones, and 3 ones make 3.Report this Argument Con ajttja forfeited this round.

And nevermind, I misread your equations again. I'm used to latex notation.

The problem is that 1/0 - 1/0 /= 0.
Posted by UndeniableReality 3 years ago
By the way, your argument is plagiarised from here: http://mathforum.org...

That will likely end up meaning an automatic loss for you.

VITOUROUS
That's much more readable. Thank you.
Why did you add 1 to the left side of the equation while keeping the other side the same? You completely fudged the algebra.
Posted by VITOUROUS 3 years ago
Valkrin,I thing you misread it x-x+x=x, which is true as this will show that x=x
Posted by VITOUROUS 3 years ago
UndeniableReality the equation is as follow
x-y+y=y
(x-y+y)/(x-y)=y/(x-y)
1+( y/(x-y))=y/(x-y)
1=0
thanks for the suggestion

Valkrin, you probably misread something. x - x + x = x is a true statement.
Posted by UndeniableReality 3 years ago
Your equations are unreadable. Please write them out more neatly, or use LateX notation, or use an equation editor to create images of your equations, or explain what you are trying to write in words, or just do a better of job of writing them out in plain text.

And as well, you admitted yourself you can't use normal mathematics to prove this statement is true.
So it wouldn't equal 3.

"Let x=y. Then

x - y + y = y"

So in other words, x-x+x=x, which is untrue. 2x doesn't equal x.

"you can use them to "prove" anything you want"
You destroyed your own argument right there...
