Question

prove that-: 2+2=5 ?

Answer 1

this is wrong question

Answer 2

@03453660 is right, but let's have some fun, anyway.
Suppose
a = b, where ab is not equal to 0
Then
a^2 = ab
a^2 - b^2 = ab - b^2
(a + b)(a - b) = b(a - b)
a + b = b
b + b = b
2b = b
2 = 1
2 - 1 = 1 - 1
1 = 0

Granted, now we have
2 + 2 = 4
2 + 2 + 0 = 4 + 0
But since 1 = 0
2 + 2 + 0 = 4 + 1
2 + 2 = 5
QED
I'm going to hell for this :D

Answer 3

thanks.

Answer 4

Hey, at least spot the error in the proof...

Answer 5

where

Answer 6

You know for a fact that
2 + 2 = 5
is false, yet I somehow "proved" it.
Something must be wrong with the proof... don't give up so quickly, look more carefully :D

Answer 7

ya i know, this is not true in the universe

Answer 8

What if I tell you that it is? And I just proved it. Prove me wrong ;)

Answer 9

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

Answer 10

i think it is correct @sunnymony

Answer 11

no r u right.

Answer 12

what do you mean?

Answer 13

@sunnymony
At some point we had

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

Which arose by dividing both sides by (a - b)
Can you see the problem there?

@mayankdevnani
I don't see how you could arrive at
2 + 2 = 5
from
2 + 2 - 9/2 = 5

Answer 14

Start with: -20 = -20
OK

Which is the same as: 16-36 = 25-45
OK

Which can also be expressed as: (2+2) 2 (9 X (2+2) = 52) 9 X 5

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

Answer 15

ok @sunnymony

Answer 16

ok but one thing this is true in the universe

Answer 17

no it's just a math joke but don't take it simple....
