Hello, Markdown!

This is a sample code block:

function greet() {
    console.log("Hello, world!");
}

And here is an inline formula: E=mc2E = mc^2

And some block formula:

eπi+1=0e^{\pi i} + 1 = 0 (abd0ac00a)n=(annan−1bnan−2[ad+12(n−1)bc]0anncan−100an),n∈Z+\left( \begin{array}{ccc} a & b & d \\ 0 & a & c \\ 0 & 0 & a \\ \end{array} \right)^n = \left( \begin{array}{ccc} a^n & n a^{n-1} b & n a^{n-2} \left[a d+\frac{1}{2} (n-1) b c\right] \\ 0 & a^n & n c a^{n-1} \\ 0 & 0 & a^n \\ \end{array} \right) , \quad n \in \mathbb{Z}^+ ∫0∞xne−xdx=n!\int_0^\infty x^n e^{-x} \mathrm{d} x = n!

A strange picture:
