Overleaf Professional: Mathematics in LaTeX

Latex has a special mode for formatting mathematical formulas. Simply enclose code that you want to be rendered in mathmode in $s.

When in this mode it is possible to displaying complicated mathematical notations.

This mode allows the use of subscripts, superscripts, fractions, summations, integrals, Greek letters and many other notations & special symbols.

In order to load a package in LaTeX, simply type \usepackage{packagenamehere} in the preamble of your document, before the \begin{document} statement.

• amsmath

  Used to typeset mathematical notation

• amsthm

  Used to typeset theorems

• amsfonts

  An extended set of fonts and symbols

• amssymb

  An extended set of fonts and symbols

• mathtools

  An extension of amsmath

• tikz

  A package for drawing graphics directly with LaTeX commands

  • Inkscape is commonly used for producing pictures, which can be included in a LaTeX document with e.g. the graphicx package. You can render LaTeX in your Inkscape pictures using Extensions->Render->LaTeX formula, and you can export as tikz-style code using the extension svg2tikz (at the time of writing the "Documentation" link is broken; an installation guide can be found here)

• tikz-cd

  A package for drawing commutative diagrams.

  • Quiver is a very useful graphical commutative diagram editor which can export tikz-cd-style code.

Not a package, but many journals require submissions to use the amsart documentclass, which you can use by including \documentclass{amsart} in your preamble. This documentclass is often considered more attractive than article documentclass, and automatically includes the amsmath and amsthm packages.
