MatueHarton Join Date Oct 2005 Posts 546 Senior Member	As far as I can remember, I was only taught PEMDAS, nothing about "left/right" etc. etc. I also vaguely remember that multiplication takes priority over division after doing what's in the parentheses. However, I don't think I ever used order of operations after 6th or 7th grade. In upper maths the school told us to use the calculators, which were coincidentally TI-83s/TI-84s which give an answer of "2". Exactly. Some people in here can't grasp this. PEMDAS or BODMAS is what we were taught and nothing to do with left to right. Left to right sounds obvious, but I'd always be looking for something from the PEMDAS rule, so maybe doing multiplication before division. I suppose this gives some people a moment to feel superior.
