1.1 Markdown & math

This page is numbered 1.1 — chapter 1, first page (order: 1).

Text formatting

You can write bold, italic, and inline code. Lists work too:

• first item
• second item
  • a nested item
• third item

And numbered lists:

1. step one
2. step two
3. step three

Block quotes look like this — handy for a definition or a key remark.

A fenced code block:

const greet = (name: string) => `Hello, ${name}!`;

Inline math

Write math between single dollar signs and it flows inside the sentence: the Pythagorean theorem is $a^2 + b^2 = c^2$, and Euler’s identity $e^{i\pi} + 1 = 0$ ties five constants together.

Display math

Put $$ on their own lines for big, centred equations:

$$\int_{-\infty}^{\infty} e^{-x^2}\,dx = \sqrt{\pi}$$ $$\sum_{n=1}^{\infty} \frac{1}{n^2} = \frac{\pi^2}{6}$$
