&gt; &quot;4 apples + 5 oranges * 18 friends&quot; ― wasn&#x27;t that meant to be &quot;(4 apples + 5 oranges) * 18 friends&quot;?<p>In the &#x27;real world&#x27;, that would clearly be the correct interpretation, even if it flies in the face of the &#x27;standard&#x27; rules of precedence. If the calculator really works that way, it only makes it <i>more</i> impressive in my book.
