I see one sentence in my book:
It is easy to see that A is as simple as B is complicated.
I know the subject of the sentence is "it" that is "A is as simple as B is complicated", but how should I understand "A is as simple as B is complicated"? If "A is as simple as B", I know that is to say A is simple as B is. Why can the "is complicated" can be added to the end? What is the subject and object of the "A is as simple as B is complicated"? Does he/she want to say A and B are simple or complicated?
