## Formatting on the Tricki

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

What it looks like What you type (Euler's identity)
[maths euler|Euler's identity] e^{i \pi} + 1 = 0[/maths] can be factorised as . $x^2 - y^2$ can be factorised as $(x-y)(x+y)$.
Some shortcuts: , , , , . Some shortcuts: $\N$, $\Z$, $\Q$, $\R$, $\C$. [maths]\begin{align} x^2 &= y \\ y^2 &= x \end{align}[/maths]

Theorem 1 (Fundamental theorem of basic arithmetic) Let . Then .
[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, . By [ref Theorem #ftba], $x = 4 - x$.

Editorial notes: Incomplete This article is incomplete. This article is missing large parts of what is required of a Tricki article.

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`).
