## Examples

Surround your LaTeX with a single $ on each side for inline rendering. ### Block Use two ($$) for block rendering. This mode uses bigger symbols and centers the result. ## Syntax Math parsing in markdown is designed to agree with the conventions set by pandoc: Anything between two$ characters will be treated as TeX math. The opening $must have a non-space character immediately to its right, while the closing$ must
have a non-space character immediately to its left, and must not be followed
immediately by a digit. Thus, $20,000 and$30,000 won’t parse as math. If for some
reason you need to enclose text in literal \$ characters, backslash-escape them and
they won’t be treated as math delimiters.


## Math Syntax Support

KaTeX is based on TeX and LaTeX. Support for both is growing. Here's a list of currently supported functions:
