MathMarkdown and math input
Write sentences normally and insert structured math when you need it. The default editor manages source delimiters for you.

Let . The area is:
three kinds of text
| kind | where it appears | what you do |
|---|---|---|
| MathMarkdown | questions, steps, solutions, and written work | Write prose and insert math nodes visually. |
| Raw expression | expression answers and grading expressions | Use one structured math field; no delimiters. |
| Plain text | labels, titles, IDs, names, and source metadata | Type ordinary text; taxonomy topics and tags are controlled catalog selections. |
visual first, source second
Use insert inline math inside a sentence and insert display math between paragraphs. Inline math stays in the prose row while display math gets its own full-width row. Fractions, roots, powers, subscripts, matrices, sums, and integrals are spatial structures. Arrow keys and Tab move through their slots. On touch devices, focusing a math field opens MathLive's math keyboard.
Source mode is optional and intended for experts. Canonical inline math uses $...$; display delimiters use $$ on separate lines. A literal dollar sign is \$. Code spans and fenced code treat dollars literally.
Mathleagues format
math-markdown-v1 is a Mathleagues-specific, versioned dialect: a restricted CommonMark subset plus KaTeX-compatible math. It is not a general Markdown, LaTeX, or external published standard.safe and accessible
Raw HTML, MDX, Markdown images, unsafe links, macros, packages, TikZ, and external-resource commands are rejected. Read-only math includes MathML for assistive technology; editor controls have screen-reader labels and keyboard access.
