Math Genius Type an equation into the Spotlight menu, and let your Mac do your math. For example, type 2*2, and you’ll get 4. If you need the area of a circle with a diameter of 10 feet, type pi*10. Need the square root of 1,024? Enter sqrt(1024). How about 64 squared? Just type pow(64,2). Unfortunately, Apple has yet to publish a list of such commands, so you’ll have to memorize the basics for now.
