Title test

Here is a paragraph with some unordered list:

item 1
item 2

But we can also create ordered lists:

ordered 1
ordered 2

Code blocks

  
my_str = "Hello "
my_str += "World!"
print(my_str)

  
a="test"
echo $a

  
$ env |grep SHELL
SHELL=/usr/local/bin/bash
PYENV_SHELL=bash

Check here for a lot of examples.

\[a * b = c ^ b\] \[2^{\frac{n-1}{3}}\] \[\int_a^b f(x)\,dx.\] \[\sum_{i=0}^n i^2 = \frac{(n^2+n)(2n+1)}{6}\] \[f(n) = \begin{cases} n/2, & \text{if $n$ is even} \\ 3n+1, & \text{if $n$ is odd} \end{cases}\] \[\begin{pmatrix} a & b\\ c & d\\ \hline 1 & 0\\ 0 & 1 \end{pmatrix}\]
