&lt;pre&gt;
Here is how I was taught to take the square root of a number back in about 6th
grade before anybody had heard of an electronic computer or calculator.  It
reminds one of the algorithm of long division, but it&#39;s lots more complicated. 
See if you can figure out how we took the square root of 2 back in 1940-1950. 

            &lt;u&gt;1.  4   1   4   2&lt;/u&gt;
           √2. 00  00  00  00      &lt;--you can keep adding pairs &quot; 00 &quot; 
            &lt;u&gt;1&lt;/u&gt;
        &lt;s&gt;20&lt;/s&gt;| 1  00
        24|&lt;u&gt;    96&lt;/u&gt;
        &lt;s&gt;280&lt;/s&gt;|    4  00
        281|&lt;u&gt;  281&lt;/u&gt;
        &lt;s&gt;2820&lt;/s&gt;| 119  00
        2824| &lt;u&gt;112  96&lt;/u&gt;
        &lt;s&gt;28280&lt;/s&gt;|  6  04  00
        28284|  &lt;u&gt;5  75  68&lt;/u&gt;  
                   28  32
