\documentclass{standalone} %standalone doesn't support aling environment, but that is redefined anyway
\usepackage{amsmath,amsfonts,amssymb} %standard
\usepackage{cancel} %already in use, however in MathJax \cancel \cancelto get more spacing than in LaTeX
\usepackage{color}
\usepackage{eurosym} %already in use, for \euro\geneuro\geneuronarrow\geneurowide\officialeuro, in MathJax they look the same
\usepackage[greek,english]{babel} %needed for teubner
\usepackage[version=4]{mhchem} %already in use, for chemistry
\usepackage{teubner} %already in use, for \copper\Copper\Digamma etc.

%%% problematic texvc definitions
%redefining % -> \% and $ -> \$ would involve changing the character code of these characters
\renewcommand{\and}{\land} %redefining a basic TeX primitive like this is a bad idea, this redefinition would cause the normal align environment to fail
%\renewcommand{\or}{\lor} %see above, when uncommented, this redefinition causes teubner to fail
\renewcommand{\part}{\partial} 
\providecommand{\ang}{\angle} %this conflicts with siunitx
\providecommand{\C}{\mathbb{C}} %this conflicts with puenc.def from hyperref package
\renewcommand{\H}{\mathbb{H}} %this conflicts with text command \H{0} which is ő
