One day a rich man mat Henry.The rich man asked ,“I hear you are very clever and nothing is difficult for you .But I don't believe.Can you tell me why you are so clever?"
Henry said,“Master ,if you don't know what I say ,please don't be angry.Now let me ask you a question.If you have a group of sheep,I send you another group.Then how many groups of sheep do you have?”
“Oh,that's the easiest question in the world.One plus one is two.Anybody knows that I have two groups of sheep."
Henry laughed and said,“You are wrong ,Master.Two groups of sheep put together is still one group .That's the easiest question in the world.
