Hello! I would love to help you! But, I'm unsure what help exactly it is you need? I do see you are working with context free grammars and the Backus Naur Form, but what areas are you uncertain with? Don't worry if you can't formulate an exact question...we can even start with question 1 and you asking, 'what is a parse tree?'.

 

*incidentally, your questions are quite timely as I'm dusting off my knowledge of parse-trees and languages, as I try to create my own LR(1) based compiler-compiler
