title: Can you simplify this expression?
body: <p>One for the mathematicians. This has gone around the office and we want to see who can come up with a better optimised version.</p>
  <pre><code>(((a+p) &lt;= b) &amp;&amp; (a == 0 || a &gt; 1) &amp;&amp; (b &gt;= p)) &amp;&amp; 
      ((b - (a + p) == 0) || (b - (a + p) &gt; 1))
  </code></pre>
  <p><strong>Edit</strong>: all data is positive int's</p>
  <p><strong>Edit</strong>: Better == simpler</p>
