Jupyter Markdown Syntax, Math, and MyST Extensions

Jupyter Notebook Markdown Cheat Sheet Reference Guide

Jupyter Notebook Markdown syntax overview

How to display mathematical formulas in Jupyter?

Use LaTeX syntax with inline formulas surrounded by $...$ and block formulas by $$...$$. Jupyter automatically renders math formulas using MathJax.

Why is my table not displaying correctly?

Ensure proper table format: each row must have the same number of columns, and there must be a separator row (|---|---|---) between header and data rows.

How to insert code blocks in Markdown?

Use three backticks ``` to surround code. You can specify a language for syntax highlighting, for example ```python.

What's the difference between MyST Markdown and regular Markdown?

MyST Markdown is an extension of Markdown that supports additional features like cross-references, admonitions, directives, etc., primarily used for technical documentation and academic publishing.
