Math Typesetting (TeX)

Edzo’s resource editor supports TeX to render Math accurately.

Rendering Math accurately can be tricky. Edzo’s Resource Editor supports inline TeX math expressions to help you clearly represent mathematical ideas in learning content. TeX can be used directly within your text and is rendered consistently across student-facing experiences.

For example, instead of writing a fraction 1 over 2 like this: 1/2

Using Tex, you can display it like this:

$\frac{1}{2}$

In addition, Edzo provides voiceover support for TeX, ensuring mathematical expressions are read aloud in a clear, human-friendly way for accessibility and audio-based learning.

​

Using TeX in the Resource Editor

TeX expressions can be embedded inline anywhere in your content by wrapping them in double curly braces:

{{ ... }}

Example

2 to the power of 4 is written as

{{2^4}}

This will render visually as a formatted math expression while remaining part of the surrounding sentence:

$2^4$

​

Expressions

**Fraction **frac{1}{2}

$\frac{1}{2}$

**Exponent **x^2

$x^2$

Supported Use Cases

You can use TeX inside:

• Paragraph text
• Instructions and explanations
• Questions and answers
• Hints, feedback, and solution text

TeX is intended for inline math, not full block equations.

​

Voiceover Support for TeX

Edzo includes a shared TeX-to-speech conversion system used by both:

• Voiceover generation
• Word alignment and playback

When a voiceover is generated, common TeX expressions inside are automatically converted into natural spoken language so learners hear math read clearly and correctly.

Example

{{\frac{1}{2}}}

Will be spoken as:

one over two

Some complex TeX expressions are not converted accurately into speech. Unknown TeX expressions are read using their command name (best-effort fallback)

​

Accessibility Notes

• TeX expressions are counted correctly for word alignment during playback
• Voiceover output is deterministic and shared between client and server
• This ensures consistent timing, highlighting, and narration across devices

If you have additional TeX constructs you would like supported for voiceover, please contact the Edzo team.
