@ShengwuLi A related q. If you need to prove a proposition which requires multiple-step proof, what would you do? 1. First, try to come up with a chain of arguments that would give you the final result (but each step may be false, even though they are reasonable conjectures.
@ShengwuLi 2. We proceed step by step. Make sure each step is correct.
The first approach is useful to keep the big picture and when you proceed to check each step, even if it does not hold exactly, you have a better idea of how to fix it without upsetting the overall proof.
