Is 2+2 Actually Five (5) Or Is It Four (4)?

I searched this one up, according to Google... This is pretty confusing for me.

"Originally Answered: How can we make 2+2=5 ? By having very large values of 2. Rounding 2.26 to the closest integer yields 2. 2.26+2.26 = 4.52, which, rounded to nearest integer, makes 5."

Is this actually true? I do not know, you guys tell me. Do you "AGREE" or "DISAGREE"

omg,we've got here already.talking about2+2=5??? i think that's just SO wrong so DISAGREE

well that could just be anything, Google has all sorts of stupid information so i think it's just a sort of prank.

@Active-Forumer
It's a trick. The first error already occurs in the second equal sign.
4 - 9/2 = 4 - 4.5 = - 0.5 = - 1/2
That's negative. However, they replace 4 - 9/2 with √((4 - 9/2)^2). That's wrong, because the latter is positive. Let me show you:
√((4 - 9/2)^2) = √((- 1/2)^2) = √(- (- 1/4)) = √(+ 1/4) = + 1/2
That's positive.

Crucially, the difference between the two terms is
√((4 - 9/2)^2) - (4 - 9/2) = 1/2 - (- 1/2) = 1/2 + 1/2 = 1

So it's no coincidence that the original 4 becomes a 5. They sneakily (and erroneously) added a hidden 1 to the right hand side of the equation.

No magic, just mathematical trickery.

Edit: The rest of the calculation is correct. √((4 - 9/2)^2) and √((5 - 9/2)^2) are actually both equal to +1/2.

This might seem surprising at first, but remember that numbers have many different looking representations.
1/2, 0.5, 0.49 (9 repeating), √((4 - 9/2)^2), √((5 - 9/2)^2), (√3)*sin(60º), etc.

These are just some of the representations of the number one half.

My cousin showed this exact thing to me in my 6th grade and I was mindblown. The entire trick is in the squaring and square root term as @Thalassokrator mentioned.

There's another trick that involves the imaginary number (i):
1 =√1 = √((-1)(-1)) Since 1 = (-1)(-1)
√((-1)(-1)) = √-1 * √-1 A known identity
√-1 * √-1 = i*i = -1 since i = √-1

But this means that 1=-1, since we get -1 at the end, but we start with 1. Oh no!
I'll let you all guess what's wrong with this one.

@Active-Forumer
The mistake lies in the step where we remove square root symbol as square root of a positive number has two answers, one positive and one negative the latter being ignored generally and person gets wrong answer.
It's just actually a trick of mind. If one falls for that they start believing of it as true and on other hand they spot it immediately.

In 1984, 2+2=5, and if you say otherwise, Big Brother is comin' to get ya!

"You need to bring your opponent into a deep dark forest where 2+2=5, and the tunnel getting back is wide enough for one" Mikhail Tal

That's what I thought when seeing this post, and if you bring your opponents in such place, it's mind-blowing even in real life. Too bad that's not the case.

2+2 isn't five

I mean, why round 2.26 when you can just write it like that. And you have to put an approximately symbol or anything that says it's not 2
