Is it easy to calculate in your head?

  I think he's asking under the (reasonable) assumption that everyone has a smartphone handy.

    For a great many business discussions, a close enough answer that's technologically unaided is way more effective than a precise answer that takes an extra 45 seconds and the incorporation of a smartphone (or one person per smartphone) into the discussion. I think of it as akin to the fluidity of a conversation between two native speakers versus a conversation with a translator in the room.

      You save a bit of time and you look pretty smart. I can do calculus in my head, but I struggle with arithmetic. My colleagues who can do fast mental math but can't do any algebra to save their lives end up looking much more competent in meetings.
