Ordinary text should use [[#emph|wiki markup for emphasis]], and should not use <code>&lt;i&gt;</code> or <code>&lt;b&gt;</code>.  However, mathematical formulas often use italics, and sometimes use bold, for reasons unrelated to emphasis.  Complex formulas should use [[m:Help:Formula|<code>&lt;math&gt;</code> markup]], and simple formulas may use <code>&lt;math&gt;</code>; or <code>&lt;i&gt;</code> and <code>&lt;b&gt;</code>; or <code><nowiki>''</nowiki></code> and <code><nowiki>'''</nowiki></code>.  According to [[Wikipedia:WikiProject Mathematics#Italicization and bolding|WikiProject Mathematics]], wiki markup is preferred over HTML markup like <code>&lt;i&gt;</code> and <code>&lt;b&gt;</code>.

The Math markup is not working at the moment because it has not been installed. Let me know if you think we need it. MW | Talk 17:47, 10 Nov 2004 (PST)

Character formatting

What it looks like What you type

Emphasize, strongly, very strongly.

  • These are double and triple apostrophes (single-quote marks), not double-quote marks.
 
''Emphasize'', '''strongly''', '''''very strongly'''''.

<math>\sin x \ln y</math>
sinx lny

<math>\mathbf{x} = 0</math>
x = 0

Ordinary text should use wiki markup for emphasis, and should not use
