Question 494217: How do I find the answer to the order of operation problem -3+7+[-(9-4)]
Answer by chessace(471)   (Show Source):
You can put this solution on YOUR website! Rule is "()" before anything, and among those, "innermost first".
1st: (9-4) = 5
2nd: +[-5] = -5
Last: -3+7-5 just keep everything separate; e.g., avoid -(3+7).
right to left, left to right OK: -1.
