Question

2 + 2 equal to 5 is equal to 6 by proof calculus

Answer 1

Let a = b

Multiply b on both sides

ab = b^2

Subtract a^2 on both sides

ab - a2 = b2 - a2

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

Divide ( b- a )on both sides

a = b + a

Let a = b = 1

1 = 1 + 1

1 = 2

now add 3 on both the sides

4 = 5

now, writing 4 as 2 + 2…

2 + 2 = 5

hence proved that 2 + 2 = 5
OK

Answer 2

Hey there !

_____________________________


Given : 2 + 2 = 4 .............(1)


To prove : 2 + 2 = 5  


Proof :  


We can say that..  


20 - 20 = 25 - 25


​​[Because both equals to 0]


20 - 20 = 25 - 25  


5 × 4 - 5 × 4 = 5 × 5 - 5 × 5


4 ( 5 - 5 ) = 5 ( 5 - 5)  


On cancelling [ 5 - 5 ] both sides..

 ∴ 4 = 5  


Now,  


As we have proved above : 4 = 5  


We can substitute value in equation (1)  


2 + 2 = 4 [ Given ]  


=> 2 + 2 = 5 [ 4 = 5 ]


Hence,  


It is proved that 2 + 2 = 5

__________________________


Now, coming to the mistakes that we have done above, because it is universal truth that


 [ 2 + 2 = 4 ]  



So, in the above solution we can't cancel  ​5 - 5 both sides  because both the sides , there are different numbers multiplied.
