LaTeX

Use paired delimiters, like \left( ... \right) and others.

• LaTeX: \left\lvert \frac{1}{x} \right\lvert
• Rendered: $\left\lvert \frac{1}{x} \right\lvert$

Use macros: \newcommand{\commandname}[num_argument]{expansion with #arg_num}

Expressions that are a single unit should stay on the same line - wrap them in braces.

When number things, text and number (e.g. Figure 1) should be on the same line. Use a non-breaking space, ~.

Spacing, thickest to thinnest: \;, \:, \,.

For set builder and conditional probability, use \mid instead of pipe.
