proof that 2+2 = 5 weird

[lightning r fun]

Start with: -20 = -20
Which is the same as: 16-36 = 25-45
Which can also be expressed as: (2+2) 2 (9 X (2+2) = 52) 9 X 5
Add 81/4 to both sides: (2+2) 2 (9 X (2+2) + 81/4 = 52) 9 X 5 + 81/4
Rearrange the terms: ({2+2}) 9/2) 2 = (5-9/2) 2
Ergo: 2+2 - 9/2 = 5
Hence: 2 + 2 = 5

"(2+2) 2 (9 X (2+2) = 52) 9 X 5" , ı didn't understand what this is. I guess there is a problem with the paranthesis or? where is the equal sign? what is "52) 9 x 5"?

The title says weird, so no surprise there are weird operators that no one could understand. May be it's a math written in the bible.

OK

OK

Which can also be expressed as: (2+2) 2 (9 X (2+2) = 52) 9 X 5
:shock:
Must have been written: (2+2)² - 9x(2+2) = 5² - 9x5

Add 81/4 to both sides: (2+2) 2 (9 X (2+2) + 81/4 = 52) 9 X 5 + 81/4
Must have been written: (2+2)² - 9x(2+2) + 81/4 = 5² - 9x5 + 81/4

Rearrange the terms: ({2+2}) 9/2) 2 = (5-9/2) 2
Must have been written: ((2+2) - 9/2)² = (5 - 9/2)²
[step a]

Ergo: 2+2 - 9/2 = 5
Must have been written: (2+2) - 9/2 = 5 - 9/2
[step b]

Hence: 2 + 2 = 5

Allelujah! you just discover what (-1/2)² = (1/2)² but -1/2 <> 1/2 (steps a and b)

thank you for clearing that up.
and for figuring out how to write the little 2.

Click on "Go Advanced" and use the special characters palette at right side.

Or press ALT 253 (this may not work according the character set selected)

sweetness.
thanks²

Nice efforts, quite logical.
But i didn't understand one of its step i.e. (2+2) 2 (9 X (2+2) = 52) 9 X 5
How this comes?

here is one that works better:
-20=-20 (it is fact)
16-36=25-45 (16-36=-20,25-45=-20)
4^2-36 = 5^2-45 (4^2=16,5^2=25)
4^2-36 = 5^2-45
4^2-2.4.9/2 = 5^2-2.5.9/2 (2.4.9/2=36,2.5.9/2=45)
4^2-2.4.9/2 +(9/2)^2 = 5^2-2.5.9/2 +(9/2)^2 (adding both the sides (9/2)^2
[4-(9/2)]^2 = [5-(9/2)]^2 (let 4=a,9/2=b)
4-(9/2) = 5-(9/2)
4 = 5
2+2 = 5

here's another one

Let x be a non-zero number, and set y=x. Thus:
x = y
x^2 = xy
x^2-y^2 = xy-y^2
(x+y)(x-y) = y(x-y)
x+y = y
2y = y
2 = 1
1 = 0
Now since 2+2 = 2+2+0 and we apply the lemma proof so that 0 = 1, 2+2+0 = 2+2+1 =5
THEREFORE
2+2 = 5

the simplest solution to a problem is to make both sides 0 , that is what you're doing in line 3

 

[lostinxlation]

0/0 = undefined.

 

[Communications_Engineer]

let x=0, then x/x =1 => inf = 1

super............. very cute..........

It's not cute ..
Square root of negative number or division by zero make your "maths" really weird ..

:wink:

a / a = 1, a <> 0
How about NaN / NaN = ?
NaN = Not a Number.

 

[bond91]

saying 0=0;
then 0*5 =0*4;
thus 4=5
things like this r complete bullshit....

 

[KIK1RIK1]

Square roots do funny things.

 

[alexan_e]

the equation comes to a point where [4-(9/2)]² = [5-(9/2)]²
This is where the error begins, this is not equal to [4-(9/2)] = [5-(9/2)]

you have to use square root at both sides to simplify
√[4-(9/2)]² = √[5-(9/2)]²

There is a special theorem that deals with this: SQRT(a²) = |a| (absolute value of a)

so the above equation becomes
|4-(9/2)| = |5-(9/2)|
|-0.5| = |0.5|
0.5 = 0.5

I'm afraid the magic is lost

whoa what an info..but in one of the expression why do 81/4 need to be added in both sides:???:

-sorry guys but im not that good in numbers the thing is i got dizzy just by seeing those(except when the figures has money related:-D)
