I don't understand. What exactly did he calculate quickly? Why is there a calculator instead of actual 1780 arithmetic tools?

    "How many seconds did this 70 year old live?" Is the question he answered, therefore the amount of leap years matters. Why there is a modern calculator in the picture or why is the post worded in such a weird way I don't know
