	* '''Math in page text''' — LaTeX written directly in the wikitext, delimited with <syntaxhighlight lang="wikitext" inline>$…$</syntaxhighlight> (inline) or <syntaxhighlight lang="wikitext" inline>$$…$$</syntaxhighlight> (display); typeset in the browser by MathJax.		* '''Math in page text''' — LaTeX written directly in the wikitext, delimited with <syntaxhighlight lang="wikitext" inline>$…$</syntaxhighlight> (inline) or <syntaxhighlight lang="wikitext" inline>$$…$$</syntaxhighlight> (display); typeset in the browser by MathJax.
	* '''Math snippets''' — an expression stored as an [[Help:Contributing/entities\|item]] with [[Special:AddMath]], whose embeds render with KaTeX. ~~Use these when~~ the ~~expression~~ should ~~be reusable~~ and ~~citable~~ (~~like~~ [[~~Help~~:~~Contributing/quotation\|quotations~~]]).		* '''Math snippets''' — an expression stored as an [[Help:Contributing/entities\|item]] with [[Special:AddMath]], whose embeds render with KaTeX.

			== Which one to use ==

			Math content should '''usually exist as in-page blocks''': <syntaxhighlight lang="wikitext" inline>$…$</syntaxhighlight> for inline math, <syntaxhighlight lang="wikitext" inline>$$…$$</syntaxhighlight> for standalone blocks. Reserve [[Special:AddMath]] (semantic math snippets) for '''known formulas''' — the named, defining results worth citing and reusing — which should always exist as standalone semantic content blocks.

			* '''In-page math''' — inline variables and symbols in prose, mathematical demonstrations, worked steps, numerical examples and computations. A worked example is [[Power_series\|Power series]]: its general form is a semantic block, while all the demonstrations and numeric examples are in-page <syntaxhighlight lang="wikitext" inline>$$…$$</syntaxhighlight> blocks.
			* '''Semantic snippets''' — the general/known formulas of a topic (e.g. the general form of a power series, a named series, a named equation). Create them with [[Special:AddMath]] and embed them on the page with <syntaxhighlight lang="wikitext" inline>{{#content:Q…}}</syntaxhighlight> so they render as standalone blocks.
			* '''Never write math as styled text''' — no raw <syntaxhighlight lang="wikitext" inline>''a''₀</syntaxhighlight>, <syntaxhighlight lang="wikitext" inline>''x''²</syntaxhighlight> or <syntaxhighlight lang="wikitext" inline><sup></syntaxhighlight>-subscript markup for mathematics. Use inline math instead: <syntaxhighlight lang="wikitext" inline>$a_0$</syntaxhighlight>, <syntaxhighlight lang="wikitext" inline>$x^2$</syntaxhighlight>.

new guide: adding and embedding mathematical expressions (via create-page on MediaWiki MCP Server)

New page

Mathematical expressions are stored as items whose content is LaTeX source; embeds render them with KaTeX.

== Adding an expression ==

Open [[Special:AddMath]] and fill the form:

{| class="wikitable"
! Field !! What it is
|-
| Label || A short description of the expression (e.g. <code>E = mc²</code> or "Newton's second law").
|-
| Content || The LaTeX source. Enclosing delimiters (<code>$…$</code>, <code>$$…$$</code>, <code>$…$</code> or <code>\[…\]</code>) are stripped automatically on save — paste from Markdown or MediaWiki as-is.
|-
| Describes || Optional: the concept the expression is about — search and pick the entity (several allowed, comma-separated).
|-
| Attributed to / Source / Date || Provenance, same as [[Help:Contributing/quotation|quotations]].
|}

Click '''Preview''' to render the content with KaTeX before saving (the preview strips the delimiters exactly like the save step).

Saving creates the item and redirects to it.

== Embedding an expression ==

From the item page, click '''Copy embed code''' and paste the snippet on any page; the expression renders as KaTeX (the raw LaTeX source is shown if JavaScript is unavailable).
