Here is a basic list of formatting tips for use on Philica. Enclose these codes between tags: so, for example, type [tex]y=x^2[/tex] to produce Anything not covered below can be found online, for example on John Forkosh’s website and in the mathematic formulae section of this page.

Basic formatting

Code	You type	You get
^ = superscript	[tex]y=x^2[/tex]
_ = subscript	[tex]y=x_i[/tex]
^ and _ together	[tex]y=x_i^2[/tex]
\frac{}{}	[tex]y=\frac{1}{x}[/tex]
\left( and \right)	[tex]y=\left(\frac{1-x}{x-1}\right)[/tex]
\sum{}	[tex]y=\sum{x_i}[/tex]
\sum{} with limits	[tex]y=\sum_1^k{x_i}[/tex]
\prod{}	[tex]y=\prod{x_i}[/tex]
\int{}	[tex]y=\int{x_i}[/tex]
\int{} with limits	[tex]y=\int_{-\infty}^\infty{x_i}[/tex]
