1+1=4 ?

Yes it is true!
I did not believe it myself.

But now I finally got it.
It took me a while to understand that "simple" calculation but it is possible to get one plus one to be four.

Do you know how?

And now, I won't give you any hints.
It is simple trust me, a bit maybe too simple :)

Maybe not as simple as 1 + 1 = 1 but not far away.
