title: How to compare multiple variables in an if statement?
body: <p>I have multiple variables:</p>
  
  <ol>
  <li><code>var1</code></li>
  <li><code>var2</code></li>
  <li><code>var3</code></li>
  </ol>
  
  <p>How can I check if any of the variables is less than 0, in one single line of code without separating it into 3 <code>if</code> statements?</p>
