[theorem ftbaFundamental 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: 
[note article 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.
