Dear Dr. Math,

   When I went to school about umpteen zillion years
   ago back sometime before the pyramids, I recall a
   longhand-division-and-guess method used to determine
   square roots, at least until we ran out of papyrus.
   Nowadays, the only answer I can seem to find is,
   "Well, you hit this button on the calculator..."

We have some good answers to this dilemma in our archives,
where we organize topics about which we receive questions.
While you're waiting for Dr. Math to answer it's always
worth searching the archives, which you can do from the
link in the top menubar of our archive pages.  Here are a
few responses to get you started:
