I remember when I was taking pre college level algebra. And I had to always wonder what the difference was. I guess it has something to do with multiplying. The parentheses always are like that. I get the concept, however I still have to wonder what the whole deal is. I could teach it to people and get by, however I think that requires A PhD person. And they would totally confuse you. At least that's my opinion.
