LaTeX

A document typesetting language widely used in academia and STEM fields for producing scientific documents containing complex mathematical formulae. LaTeX encodes mathematical content as plain text markup commands (e.g., \frac{a}{b} for a fraction), which makes it inherently accessible through screen readers and Braille displays because the formulae can be read linearly as text. While not designed as an accessibility tool, LaTeX has become an important instrument for accessible mathematical content authoring, offering an alternative to visual equation editors that are difficult to use with assistive technologies. LaTeX syntax is also supported in web tools like MathJax and KaTeX for rendering accessible mathematics on websites.
