<h2>Sum square difference</h2>
<h3>Problem 6</h3>
<div style="font-size:80%;color:#999;">Published on 14 December 2001 at 06:00 pm [Server Time]</div>
<div class="problem_content" role="problem">
<p>The sum of the squares of the first ten natural numbers is,</p>
<div style="text-align:center">1<sup>2</sup> + 2<sup>2</sup> + ... + 10<sup>2</sup> = 385</div>
<p>The square of the sum of the first ten natural numbers is,</p>
<div style="text-align:center">(1 + 2 + ... + 10)<sup>2</sup> = 55<sup>2</sup> = 3025</div>
<p>Hence the difference between the sum of the squares of the first ten natural numbers and the square of the sum is 3025 − 385 = 2640.</p>
<p>Find the difference between the sum of the squares of the first one hundred natural numbers and the square of the sum.</p>
