<h1 class="center">Always End With 1089</h1>
<h3 class="center">Add two numbers together and always end with 1089.<br> <br>
Here is How:</h3>
<div class="center">
<div style="display:inline-block; max-width:200px;"> Pick a three digit number.
<b> The three digits used must be different</b>*. i.e. 123
</div>
<div style="display:inline-block; width:50px;">
<img src="images/arrow.gif" alt="right arrow" height="30" width="30">
</div>
<div style="display:inline-block; max-width:200px;">Reverse that number. 123 becomes 321</div>
</div>
<p class="center"> <img src="images/arrow2.gif" alt="arrow new line" height="47" width="320"> </p>
<div class="center">
<div style="display:inline-block; max-width:200px;">Take the smallest three digit number from the largest.
<br> 321 &minus; 123 = 198
</div>
<div style="display:inline-block; width:50px;">
<img src="images/arrow.gif" alt="right arrow" height="30" width="30">
</div>
<div style="display:inline-block; max-width:200px;">Take the answer and reverse that number. 198 becomes 891</div>
</div>
<p class="center"> <img src="images/arrow2.gif" alt="arrow new line" height="47" width="320"> </p>
<div class="center">
<div style="display:inline-block; max-width:200px;">Add that number to the
answer of the subtraction.
<br>891 + 198 = 1089
</div>
<div style="display:inline-block; width:50px;">
<img src="images/arrow.gif" alt="right arrow" height="30" width="30">
</div>
<div style="display:inline-block; max-width:200px;">
<h3>The answer will be 1089!</h3>
</div>
</div>
<div class="center">
<h4>So why does it do this? <br> <a href="1089algebra.html">Find out here</a></h4>
</div>
<div class="center">
<br>
</div>
<br>
<div class="center80">
<h3>Footnotes</h3>
<p>* But I ended with <b>198</b> not <b>1089</b> ... !</p>
<p>This happens if you pick
a number like 546. </p>
<p>546 goes like this: 645&minus;546=99, then 99+99=198. </p>
<p>BUT if you assume that <b>099 is a 3 digit number</b>, you will get: <br>
990&minus;099=891, and 891+198=1089</p>
<p><br></p>
<p>* If you don't pick three different digits then this might happen: <br>
343&minus;343=0, 0+0=0</p>
