Formatting on the Tricki

See also the formatting of sections page.

You can experiment with markup and other features of the Tricki in the Sandbox.

x^2 - y^2 can be factorised as (x-y)(x+y). $x^2 - y^2$ can be factorised as $(x-y)(x+y)$.

[theorem ftba|Fundamental theorem of basic arithmetic]Let $x = 2$. Then $x + x = 4$.[/theorem]
Note: always use descriptive IDs and not position dependent ones in order to make restructuring articles earier.
Proof of Theorem 1. This is obvious.□
 [proof ftba]This is obvious.[/proof]
By Theorem 1, x = 4 - x. By [ref Theorem #ftba], $x = 4 - x$.

Notes can be specified at the article level and the section level. They can be one of three types: 'incomplete', 'contributions wanted', or 'attention'. See the page about editorial markup for more information.

Available theorem-like environments:

  • theorem (numbering: theorem)

  • lemma (numbering: theorem)

  • corollary (numbering: theorem)

  • conjecture (numbering: theorem)

  • proposition (numbering: theorem)

  • sublemma (numbering: theorem)

  • problem (numbering: problem)

  • exercise (numbering: problem)

  • question (numbering: problem)

  • definition (numbering: definition)

  • claim (no numbering)

  • remark (no numbering)

  • remarks (no numbering)

The theorem-type environments are rendered in italics; the others are not.

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).
