Question

2+1=4 amyone can say how

Answer 1

......... ............

Answer 2

0=0

4-4=4-4

2^2-2^2=2^2-2^2

Now see 2^2-2^2=4-4

It can be written as 2(2-2)

It can also be written (2-2)(2+2)

since (a-b)(a+b)=a^2-b^2

So:

2(2-2)=(2+2)(2-2)

2-2 gets cancelled

2=4[proved]

So , 2/2=4/2

1=2

1+2

=2+2 as 1=2

=4[proved]
