## Description
<section id='description'>

It is possible to write five as a sum in exactly six different ways:

<div style='margin-left: 4em;'>
  4 + 1<br>
  3 + 2<br>
  3 + 1 + 1<br>
  2 + 2 + 1<br>
  2 + 1 + 1 + 1<br>
  1 + 1 + 1 + 1 + 1<br>
</div>

How many different ways can one hundred be written as a sum of at least two positive integers?
