[theorem ftba|Fundamental theorem of basic arithmetic]Let $x = 2$. Then $x + x = 4$.[/theorem]
Note: always use descriptive IDs, not position dependent ones.
By Theorem 1, x = 4 - x. By [ref Theorem #ftba], $x = 4 - x$.

Available theorem-like environments:

  • theorem

  • lemma

  • corollary

  • conjecture

  • proposition

  • claim

  • problem

  • question

  • definition

Problems and questions are numbered separately, as are definitions.

Lists can be nested to an arbitrary depth by putting more asterisks at the beginning of the line.

There are three levels of headings (from === to =====).

Images can also be floated to the right (right instead of left) or centred (centre).
