Accessible Mathematics: LaTeX Formatting Guide explains structured markup, spoken math, keyboard use, alternative text, and testing.
Core notation for Accessible Mathematics
In accessible mathematics, the notation usually represents source notation, rendered output, semantic structure, code points, macros, and destination formats. The table below gives a compact starting set for accessible mathematics; define any local variation before the first calculation.
| Concept | Notation | How to read it |
|---|---|---|
| MathML operator | \texttt{<mo>−</mo>} | semantic operator element |
| Aligned equations | \begin{aligned}a&=b+c\\d&=e\end{aligned} | multi-line alignment at relation signs |
| Accessible label | \text{“x squared plus one”} | plain-language reading when a text alternative is needed |
| Macro | \newcommand{\vect}[1]{\mathbf{#1}} | reusable semantic notation command |
LaTeX patterns that preserve the structure
For accessible mathematics: guide, group arguments explicitly, use named operators, scale delimiters to the enclosed expression, and align rows at the mathematical relation being compared.
\texttt{<mo>−</mo>}
\begin{aligned}a&=b+c\\d&=e\end{aligned}
\text{“x squared plus one”}For accessible mathematics, keep multi-character labels inside \text{...} or an appropriate operator command. In accessible mathematics, use braces whenever a subscript, superscript, numerator, denominator, or radical contains more than one token.
Conventions to state beside the formula
- Keep editable source with the rendered result.
- Use semantic commands for accessible mathematics rather than visual spacing tricks.
- Test the final destination, export path, and assistive-technology reading of the accessible mathematics notation.
Renderer and export checks
Render one demanding accessible mathematics example in the actual destination. For accessible mathematics, compare the source, browser output, office-equation output, and exported PDF so grouping, indices, minus signs, and line breaks remain unchanged.
Accessibility and portability
Keep the accessible mathematics source selectable and editable. For an isolated character in accessible mathematics, Unicode text may be sufficient; for structured expressions, preserve LaTeX, MathML, or a native equation object. When an image of accessible mathematics is unavoidable, describe the operation, inputs, conditions, and conclusion rather than listing glyph names.
Verification checklist
- Copy and paste into plain text.
- Validate with a second renderer or browser.
- Inspect keyboard, zoom, PDF, and screen-reader behavior for the accessible mathematics example.
- Confirm every symbol used in accessible mathematics has one defined meaning in the local context.
- Reopen the exported file for Accessible Mathematics: LaTeX Formatting Guide and compare it with the editable source.
