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:
| Field | What it is |
|---|---|
| Label | A short description of the expression (e.g. E = mc² or "Newton's second law").
|
| Content | The LaTeX source. Enclosing delimiters ($…$, $$…$$, \(…\) or \[…\]) 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 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).
