why current frame number not equal to current page number?
<p>I use latex beamer to write ppt, export to pdf,</p>

<p>to display frame number, i add follow line in beamer header</p>

<pre><code>\setbeamertemplate{footline}[frame number]
</code></pre>

<p>After exporting to PDF,  pdf file has 11 pages, but frame number just 4. </p>

<p>As follow:</p>

<p><a href="https://i.stack.imgur.com/gXTWc.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/gXTWc.png" alt="enter image description here"></a></p>

<p>what i want is current frame number equal to current page number,</p>

<p>see the figuage,  the current frame should be 8/11( now current is 4/4, i think it's wrong), same as page number.</p>
