Question

2+2=5
kaise aya explanation kesaath ans do​

Answer 1

It is not a usuable but a prank proof instead------

We take 2 variables 'a' and 'b',where a=b

=>a=b

=>a×a=b×a (multiplying a on both sides)

=>a²=ab

=>a²-b²=ab-b² (subtacting b² from both sides)

We know that a²-b²=(a+b)(a-b)

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

=>a+b=b

=>2b=b (Replacing 'a' by 'b',since we had taken a=b)

=>2=1

=>1=2

=>1+3=2+3 (Adding 3 on both sides)

=>4=5

=>2+2=5 (Since,4 can be expressed as 2+2)

From,this process,we can also proof many things like---

i.2=1 (proved above)

ii.1+3=5 (4 can be also expressed as 1+3)

iii.0+4=5 (4 can be also expressed as 0+4)

Etc......
