Whilst I was attending school my teachers assured me that I would use the math I was learning in my day to day life. They lied. I can't remember the last time someone asked me to get the volume of a pyramid, or what the cosine of 12.3234 was.
Since I am but a mere blogger PEMDAS isn't all that useful to me, but if you find yourself wishing for a more competent calculator for OS X you should check it out. It is a scientific calculator that supports formulas, has a nice design, and has a low, low price (free).
