There is indeed a proof out there that seems to prove that 2 + 2 = 5, and it is not about rounding. Whenever anything is rounded you need to accept a degree of error within your answer, in this case that degree of error is 1.

I'll admit that I didn't see the satire at first (though if I had gotten here through the forum, instead of a wayward search, I'd like to think that I would have gotten it).

But, I started this post with the intent of showing you how its done... and though I see the futility, I plan to follow through. The said proof goes like this:

two variables are set equal
X = Y
Add X to both sides
X + X = Y + X
Simplify
2X = X + Y
subtract 2Y from both sides
2X - 2Y = X + Y - 2Y
simplify
2X-2Y = X - Y
Factor
2(X - Y) = 1(X - Y)
Devide both sides by (X - Y)
2 = 1
Add 1 to both sides
3 = 2
Add 2 to both sides
5 = 2 + 2

Another proof exists, my calculus teacher showed it to us once, but after 2 years of calculus I still am not confident enough to repeat it and support it (nor do I remember it). It, like this one, has an error. Incase you didn't catch it, (X - Y) = 0, which we divided by. That's a math no-no. As we divide by numbers aproaching zero the answers get increasingly huge, so really we just proved that:
<span style="font-family:Symbol">&#165; + 1 = &#165;
Which is true.

Sir, if you are going to use math in your satire, make it good math.
