<PRE><B>Question 883794</B>
&lt;pre&gt;
Put four blanks for the digits:
_ _ _ _

&lt;/pre&gt;
&gt;&gt;..the value of the digit in my tens place is 70..&lt;&lt;
&lt;pre&gt;
So the tens digit is 7 because 7 times 10 is 70

_ _ &lt;u&gt;7&lt;/u&gt; _
&lt;/pre&gt;
&gt;&gt;..the sum of the digit in my tens and ones places is 16..&lt;&lt;
&lt;pre&gt;
Since the tens digit is 7 we have to add 16-7 or 9 to 7 to get 16,
so the digit in the ones place is 9

_ _ &lt;u&gt;7&lt;/u&gt; &lt;u&gt;9&lt;/u&gt;
&lt;/pre&gt;
&gt;&gt;..the value of the digit in my thousand place is the square of 2..&lt;&lt;
&lt;pre&gt;
The square of 2 is 2&lt;sup&gt;2&lt;/sup&gt; = 2×2 = 4. So we put 4 in the
thousands place:

&lt;u&gt;4&lt;/u&gt; _ &lt;u&gt;7&lt;/u&gt; &lt;u&gt;9&lt;/u&gt;
&lt;/pre&gt;
&gt;&gt;..the digit in my hundred place is 2 more than the digit in my thousand place..&lt;&lt; 
&lt;pre&gt;
So we add 2 to the 4 and get 6 for the hundreds digit:

&lt;u&gt;4&lt;/u&gt; &lt;u&gt;6&lt;/u&gt; &lt;u&gt;7&lt;/u&gt; &lt;u&gt;9&lt;/u&gt;
