Just a quick post – if you’re an OS X user, you’ll know about Spotlight. Basically, it acts as a form of system wide search, allowing documents, applications etc to be located and opened. Something you may not know however, is that you can use it to perform math equations. I do this many times over the course of a day, saving me from having to open the calculator app on my Mac or iPhone. Naturally, it operates according to BOMDAS (BODMAS) which allows for equations such as: (8^2*5)/25 to be entered. Try it out: CMD + Space.
