== Mathematics ==

- Variables within text in italics ($ $).
- Do not use the same variable name for different things.
- Avoid sub- and superscripts.
- Do not begin sentences with variable names.
- Repeat the type of variable when using a variable, but be careful with the placing of the variable:
The values are represented in a list of numbers L.
=> The values are represented in a list L of numbers.
- Not every peace of math is an equation or formula. Maybe it is just a term.

- Definitions, Theorems etc.
  - should be self-contained
  - usually contain an (implicit) "Given..." part followed by a "Then ..." part
  - should be put into context / introduced / explained. Do NOT just rephrase a complex formula in words, but explain the meaning.

- Beautify:
  - Take care of the spacing, e.g.: +x (sign) versus + x (addition)
  - Take care of line breaks.
  - Do not use 'x' or \times as multiplication symbol. Use \cdot or just a space.
  - paratheses in different sizes: \left( \sum ... \right)
  - x_1 + x_2 + \cdots + x_n
  - x_1, x_2, \ldots, x_n
