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 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 <i> or <b>. However, mathematical formulas often use italics, and sometimes use bold, for reasons unrelated to emphasis. Complex formulas should use <math> markup, and simple formulas may use <math>; or <i> and <b>; or '' and '''. According to WikiProject Mathematics, wiki markup is preferred over HTML markup like <i> and <b>.

<math>\sin x + \ln y</math>
sin''x'' + ln''y''

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

A typewriter font for monospace text or for computer code: int main()

  • For semantic reasons, using <code> where applicable is preferable to using <tt>.
A typewriter font for <tt>monospace text</tt>
or for computer code: <code>int main()</code>

You can use small text for captions.

You can use <small>small text</small> for captions.

You can strike out deleted material and underline new material.

You can also mark deleted material and inserted material using logical markup rather than visual markup.

  • When editing regular Wikipedia articles, just make your changes and don't mark them up in any special way.
  • When editing your own previous remarks in talk pages, it is sometimes appropriate to mark up deleted or inserted material.
You can <s>strike out deleted material</s>
and <u>underline new material</u>.

You can also mark <del>deleted material</del> and
<ins>inserted material</ins> using logical markup
rather than visual markup.

Subscripts:
x1 x2 x3

Superscripts:
x1 x2 x3 or x¹ x² x³

  • The latter method of superscripting can't be used in the most general context, but is preferred when possible (as with units of measurement) because most browsers have an easier time formatting lines with it.

ε0 = 8.85 × 10−12 C² / J m.

1 hectare = 1 E4 m²

&epsilon;<sub>0</sub> =

C&sup2; / J m.

1 [[hectare]] = [[1 E4 m²]]

&rarr; &harr;

Spacing in simple math formulas:
Obviously, x² ≥ 0 is true.

  • To space things out without allowing line breaks to interrupt the formula, use non-breaking spaces: &nbsp;.


Obviously, ''x''&sup2;&nbsp;&ge;&nbsp;0 is true.

Complicated formulas:

<math>\sum_{n=0}^\infty \frac{x^n}{n!}</math>
  • See m:Help:Formula for how to use <math>.
  • A formula displayed on a line by itself should probably be indented by using the colon (:) character.


: <math>\sum_{n=0}^\infty \frac{x^n}{n!}</math>

Suppressing interpretation of markup:
Link → (''to'') the [[Wikipedia FAQ]]

  • Used to show literal data that would otherwise have special meaning.
  • Escape all wiki markup, including that which looks like HTML tags.
  • Does not escape HTML character references.
  • To escape HTML character references such as &rarr; use &amp;rarr;


<nowiki>Link &rarr; (''to'') 
the [[Wikipedia FAQ]]</nowiki>

Commenting page source:

  • Used to leave comments in a page for future editors.
  • Note that most comments should go on the appropriate Talk page.
