Pretty Text and Math (Markdown Language)

One great feature of the Jupyter Notebooks is that they can contain formatted text, and mathematics, using the Markdown language.

Markdown is a rich language: a quick introduction to it is available here: https://guides.github.com/features/mastering-markdown/

Some quick points.

Editting and typesetting

You simply type your text and Markdown symbols into a cell, and hit "shift-return" to typeset the cell into pretty text (and math). Click on the cell again to undo the typesetting, so you can edit and fix your text. Make sure, of course, that you have marked the cell as "Markdown" and not "Code."

Headers

Headers are made by starting the line with one or more hash marks #

#### This is a level-4 header, in text form
