title: How to get the right arithmetic value?
body: <p>Is it possible through some sort of arithmetic or logic operation (no if/else) to make the following pairs of binary values (only 1 and 0) have the following results?</p>
  
  <pre><code>1 | 1 -&gt; 0
  0 | 1 -&gt; 1
  1 | 0 -&gt; 1
  0 | 0 -&gt; 0
  </code></pre>
  
  <p>(The operation must be the same for every row).</p>
