In the previous episodes: generic mistakes and suggestionsand how to fix the spacing and math environments in your papers. Continuing along these lines, in this post we will see some common mistakes done when writing mathematics. As for the previous episodes, the source for all figures in this post is in a writeLaTeX.
This page outlines some more advanced uses of mathematics markup using LaTeX. Further information is provided in the labels and cross-referencing chapter. To have the enumeration follow from your section or subsection heading, you must use the amsmath package or use AMS class documents.
