This is not really true. Again, it's not like reading a sentence. You really need to put the parenthesis in there to show what to do first.

It is like reading a sentence, unless there is an operation that must be solved first; you don't need parantheses to indicate that it should be solved left to right. If I wrote 3-2+1, I would always solve 3-2 first. I don't have to put (3-2)+1 because the parantheses are redundant. BUT if I wanted 2+1 solved first, I would have to use parantheses, 3-(2+1).
