In a case where they are both present you just go from left to right.
Don't know why someone would go right to left or otherwise.

If this was middle school math you would be soooo very correct. You would do the parenthesis first then just do it left to right. This is algebra tho. The equation is not written incorrectly at all, google may have changed it to fit people who just fail at math. Here is a simple math lesson:
When it looks like 48/2 * (9+3) this would equal 288, this means do the addition first then left to right and you get 288.
When there is no * between the parenthesis (which you will never find outside middle school math) and it looks like:
48/2(9+3) this equals 48/(2*(9+8)) This is implied in all level 1 collage algebra books, I know my husband is a CIS student and deals with a crap load of math. It would look like this being solved:
48/2(9+3) = 48/2(12) in which the parenthesis are still in play and means the multiplication must be done before the division. In a basic text book to teach this it could possibly be written as such:
2(9+3) In which this would mean you do the multiplication first then divide.
