How do I make this in LaTeX? I keep losing track of the brackets.

  • Do you know about the \cfrac macro provided by the amsmath package? – Mico Dec 30 '16 at 18:25
  • I don't have any packages, I use latex2png.com, as my teacher told me to use it. – JC123 Dec 30 '16 at 18:26

    \cfrac works at that site, I just tried – David Carlisle Dec 30 '16 at 18:31

    Checked with y = 2+\cfrac{1}{1+\cfrac{1}{2+\cfrac{1}{1+\dots}}} on that site, it works – user31729 Dec 30 '16 at 18:32

    See this answer of mine for being able to use the friendlier syntax e=\xcontfrac{2;1,2,1,4,1,1,6+\cfraccdots} (in math mode, of course). – egreg Dec 30 '16 at 19:09

The following code is "full" LaTeX:

\documentclass{article}
\usepackage{amsmath} % for "\cfrac" macro
\begin{document}
\[
e=2+\cfrac{1}{1+\cfrac{1}{2+\cfrac{1}{ 1+\cfrac{1}{1+\cfrac{1}{4+\cfrac{1}{1+\cfrac{1}{1+\cfrac{1}{6+\cdots}}}}}}}}
\]
\end{document}

enter image description here

If you want, you can copy and paste the math part -- the stuff between \[ and \] -- into latex2png.com.

    I am SO grateful! Thank you very much Mico (and all others helping me out) – JC123 Dec 30 '16 at 18:35

    I learned something new today as well: the existence of the site latex2png.com! – Mico Dec 30 '16 at 18:36

    Our teacher told us we had to use it in our assignments, glad we could learn each other something. I think it's really nice to get into such a respectful and friendly community – JC123 Dec 30 '16 at 18:38

Or, using no packages:

\documentclass{standalone}
\begin{document}
$e=
2+\frac{1}{1+\frac{1}{2+\frac{1}{1+\frac{1}{1+\frac{1}{4+\frac{1}{1+\frac{1}{1+\frac{1}{6+\cdots}}}}}}}
}
$
\end{document}

Yields:

Although \cfrac works better, this seemed to be what you were originally trying to get.

The copyable code for the website would be:

e=2+\frac{1}{1+\frac{1}{2+\frac{1}{1+\frac{1}{1+\frac{1}{4+\frac{1}{1+\frac{1}{1+\frac{1}{6+\cdots}}}}}}}}
