mmmmm okey, for google tradiction : google tradiction translates the classical arabic only it do not translate local languages of Arab countries like: egiptian language- algerian language- tunisian- lebanese- marroccan...... . for this you don't find it . and for your first question yes you can converse with a Saudi national after learning Egyption dialect because all arabic languages are similar like completely : Chinese, Japanese and Korean are smilar too . and for your secondly question all arabic languages are closer rather to the classical arabic of quran and i want to tell and inform you than the arabs are understand each one another =)
