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]
By theorem [ref ftba], x - 2 = 0. By theorem [ref ftba], $x - 2 = 0$.

Example tags do not need to be closed, unlike theorem tags.

Available theorem-like environments:
  • theorem
  • lemma
  • corollary
  • conjecture
  • proposition
  • claim
  • problem
  • question
  • definition
Problems and questions are numbered separately, as are definitions. List can have be nested to an arbitrary depth by putting more asterisks at the beginning of the line. There are four levels of headings (from === to ======). Images can also be floated to the right (right instead of left) or centred (centre).
