I asked Google with these keywords "algorithm of finding square root of an integer number manually".


Google knows everything, the major thing is to ask a right question.



This time Google provided these links:

It is how my teachers taught me many years ago, in my 6-th grade.




To be honest, after learning this algorithm in school, I did not use it in my life NO ONE single time.
(Although all my life was making scientific computing).


So, in my view, this knowledge does belong to the category of absolutely useless subjects.
