<PRE><B>Question 1096008</B>
&lt;pre&gt;&lt;b&gt;
The other tutor doesn&#39;t seem to know that 0 is 
NOT a positive integer.  Here&#39;s the solution:

1&lt;sup&gt;2&lt;/sup&gt; + 1&lt;sup&gt;2&lt;/sup&gt; + 1&lt;sup&gt;2&lt;/sup&gt; + 2&lt;sup&gt;2&lt;/sup&gt; + 3&lt;sup&gt;2&lt;/sup&gt; = 4&lt;sup&gt;2&lt;/sup&gt;

Note: If they had to be all different, the answer 
would have been

1&lt;sup&gt;2&lt;/sup&gt; + 3&lt;sup&gt;2&lt;/sup&gt; + 4&lt;sup&gt;2&lt;/sup&gt; + 5&lt;sup&gt;2&lt;/sup&gt; + 7&lt;sup&gt;2&lt;/sup&gt; = 10&lt;sup&gt;2&lt;/sup&gt;
