You have major gaps in knowledge (for example, in this thread you effectively said you don't know asymptotic analysis of algorithms). Start with something simpler - check what is a polynomial, big O, a Turing machine etc. Backtrack to simple things. Be persistent. Search for a textbook like Cormen's Introduction to Algorithms or Hopcroft/Ullman's Introduction to Automata Theory, and slowly read it. You can't be helped by using "my own words"; my own word for "polynomial" is "polynomial", it is commonly accepted and understood by the computer science community. It can't be dumbed down.
