From the February 1997 edition of FromNowOn.Org: The Educational Technology Journal. http://fromnowon.org/feb97/teach.html -|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|- SQUARE ROOTS WITHOUT A CALCULATOR 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: Manual Method to Find Square Roots http://mathforum.org/dr.math/problems/gilman11.html Square Roots: Estimate, Divide, Average http://mathforum.org/dr.math/problems/schweitzer2.4.97.html Square Roots without a Calculator http://mathforum.org/dr.math/problems/steve.8.6.96.html -|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|- CHECK OUT OUR WEB SITE: The Math Forum http://mathforum.org/ Ask Dr. Math http://mathforum.org/dr.math/ Problem of the Week http://mathforum.org/geopow/ Internet Resources http://mathforum.org/~steve/ Join the Math Forum http://mathforum.org/join.forum.html Send comments to the Math Forum Internet Newsletter editors _o \o_ __| \ / |__ o _ o/ \o/ __|- __/ \__/o \o | o/ o/__ /\ /| | \ \ / \ / \ /o\ / \ | \ / | / \ / \ |
