# Math and Science Formulas Using LaTeX

Pressbooks supports LaTeX code, a typesetting language that is often used to format complex science and math equations.

You can enter LaTeX code into the editor by putting `$latex`

before your LaTeX code. At the end of your LaTeX code, add a dollar sign ($) to tell Pressbooks that you are finished entering LaTeX code. Your LaTeX code should look like this:

`$latex`

`enter-your-latex-code$`

This LaTeX code then gets converted to an image when viewed in a browser or exported to an ePub or PDF.
