title: MathJax, my code doesn't seem to work completely fine, can anybody have a look?
body: <p>I'm having some weird problem with MathJax. Everything on my site works fine, every MathJax snippet, except some subpage. I'm making a website about functions and their transformations in Polish.
  When I'm trying to perform the code, it's like it breaks performing in the middle.
  I'm attaching a link to the image with the code and the results: <img src="https://i.stack.imgur.com/GrQsd.png" alt="http://s11.postimg.org/d9nrfiw8z/Bez_tytu_u3.png">
  I'm sure I've checked the code in detail... It's really important for me to work fine!
  Thanks in advance.</p>
  
  <p>The code:</p>
  
  <pre><code>Funkcja $f(k*x)$ rozciąga się w poziomie dla $k&gt;1 \lor k&lt;-1$, zaś dla $ 1&lt;k \land k&lt;-1 $ jest ona ściśnięta w poziomie.
  Funkcja $k*f(x)$ ściska się w pionie dla $k&gt;1 \lor k&lt;-1$, zaś dla $ 1&lt;k \land k&lt;-1$ jest ona rozciągnięta w pionie.
  Warto zaznaczyć, iż gdy $k$ jest ujemne, to funkcja dodatkowo obraca się symetrycznie wokół osi OX dla $k*f(x)$ i wokół osi OY dla $f(k*x)$.
  </code></pre>
  
  <p>Oh, now I got it... The code was broken in the same place where "1&lt; k" is placed, and Firefox reads is as a HTML tag, and this made the MathJax code run not properly.
  Question can be closed </p>
