The best feature on the Mac's built in calculator is the paper tape (⌘+t) which I stumbled on ages ago while accidentally having the calculator open and trying to open a new tab in my browser.
I always leave it open now and it has saved me countless times. Really with the iOS version had this feature built in as well.
