I have been working on a problem for hours now - trying to prove a statement which has no premises. This is what the problem looks like:
You can see that so far I've tried to work my way backwards, starting with the answer, but without premises I am finding it very difficult to move forward. I've gone through my textbook back and forth and the examples in there are much less complex than this one. I'm pretty sure this is a rather obvious one, but I just can't seem to figure it out.
Thanks so much.
