I'm trying to insert a couple of numbered equations into a latex document, the equation is very basic yet all the normal operators =, + and - don't appear when I compile the document. I commented everything out except for the equation and still get the same output so I don't think it is as a result of anything before it in the document. This is the first document I'm writing using latex so chances are its something really basic!! the two equations are
\begin{equation}
Z = \frac{c_o - 4c_p}{c_{Si} + Rc_M } - 2
\end{equation}
and
\begin{equation}
NC = 4 - 2Z
\end{equation}
This is the header to the document
\usepackage{baththesis}
\usepackage[small,it]{caption}

\usepackage[a4paper, top=2.5cm, bottom=2.5cm, left=4cm, right=2.5cm,includeheadfoot,head=3cm, headsep=6ex, headheight=4ex]{geometry} % setting page to A4

, they'll be marked as code, as can be seen in my edit. You can also highlight the code and click the "code" button (with "{}" on it).baththesis
doesn't seem to be included in texlive full, and commenting it out doesn't solve the problem, so I suggest it can be removed from the MWE.\usepackage{fouriernc}
does solve the problem (but changes the aspect of the equation as well).fouriernc
andtxfonts
. It is not present when one usesnewtxtext
but it is still present withnewtxmath
. Also inverting the order of loading thefouriernc
andtxtext
solves it.fouriernc
andtxfonts
doesn't make sense. Use only either one of them. If you prefer Times to New Century Schoolbook, then try\usepackage{newtxtext,newtxmath}
instead of\usepackage{txfonts}
