Prove 2 + 2 = 5.

[Megalomania]

If you're refering to me, then fine.

2.4000000000000000000000000000000000000000000000000 etc. + 2.4000000000000000000000000000000000000000000000000 etc. = 4.8000000000000000000000000000000000000000000000000 etc.

hmmm divide by 0?

first figure out that 2=1:

a = b

a2 = ab

a2 - b2 = ab-b2

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

a+b = b

b+b = b

2b = b

2 = 1

now if 2=1, then 1+1=2

so 2+2=2

and if that's not the solution, maybe take it a step further:

1+1=1

a = b

a2 = b2

a2 - b2 = 0

( a - b )( a + b ) = 0

( a - b )( a + b )/( a - b ) = 0/( a - b )

1( a + b ) = 0

( a + b ) = 0

1 + 1 = 0

2 = 0

1 = 0

1 + 1 = 1

so 2+2=1

people think way too hard,

1 + 1 + 1 + 1 = 4

which is equivallent to

2 + 2

and just for reference

The Number 2 = 1 + 1 (note: 2 One's)

therefore

2 + 2 = 4!

its not rocket science people!

a = b

a2 = ab

a2 - b2 = ab-b2

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

(-a+b=B )

(-b+b=0)

a = b

a2 = b2

a2 - b2 = 0

( a - b )( a + b ) = 0

( a - b )( a + b )/( a - b ) = 0/( a - b )

1( a + b ) = 0/(a - B )

( a + b ) = 0/(a - B )

1 + 1 = 0/(1 - 1) division by 0

maybe in measurements that would be true, but we can define numbers however we want, so in the question 2+2=4 2=2.0000000000000000000000000000 however,

-20=-20

16-36=25-45

4^2-36=5^2-45

4^2-2*4*9/2=5^2-2*5*9/2

4^2-2*4*9/2+(9/2)^2=^2-2*5*9/2+(9/2)^2

(4-(9/2))^2=(5-(9/2))^2 (take the square root)

4-(9/2)=5-(9/2) (divide by -(9/2))

4=5

2+2=5

there is, however, one flaw with this math, and that is that when you take a square root, there are two possible answers. For example, the square root of 25 is 5 OR -5. There is also one other way to prove this, although I am not sure that it is correct. This is something I came up with on my own, that one I took off another web site. Anyway, here it is:

Let A=4

and B=5

A(5A-4B)=B(5A-4B) divide by (5A-4B) (this is a true statement, by the way)

A=B

4=5

2+2=5

But no # is equal to that #.

Yes it is.

Case closed.

finally!! and it only took 4 1/2 years....

And here I was wondering why that Unexplained Math Forum never really took off like I thought it would...The joint is JUMPIN!!

[Cherus]

2+2=5??

a=b

a^2=a*b

a^2-b^2=a*b-b^2

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

a+b=b

if a=1 and b=1

then

2=1!!!!

2 + 2 = 4, right?

No, not in all cases.

2 (beers) + 2 (ciggerates) = 5 (bad smelling sticky room)

Ok, I couldn't think of anything 'witty', but you get what I'm on about...

But no # is equal to that #. Pi (3.14 etc.) never stops.

2 (way way way (a few trillion decimal places)) has to equal like 2.000000000000000000000000000000000001 or somethin' similar; sense nothing in this world (humans created it, and we arn't perfect) is perfect, that has to be the case.

It may not be 5, but certainly not 4.

ok~....if you are looking at numbers that way........then all other numbers would eventually have the same outcome(and no it's not after a few trillion decimal places now is it.......it's after a few trillion o's)..therefore every other two random number you throw out there with a + in the middle doesn't equal what we know as the answer to be.............you could be really out there and say...well if 2(really means 2.5).......then 2+2 would equal 5

actually...now i have woken up properly and thought about your question a little more........your trying to say that 2.0000000....by a trilion 0's will eventually have a 1 at the end right!!!!.......if that's the case......then the answer of 2+2 still would not equal 5........

2.000000000000001 +2.000000000000000001 would equal 4.0000000000000000000000002......going by what your saying........
