Even has Latex!

How to add $\LaTeX$ commands to your posts:

Inline

To add inline math, you can use $ <math> $. Here is an example:

$ \sum_{i=0}^j \frac{1}{2^n} \times i $ becomes $ \sum_{i=0}^j \frac{1}{2^n} \times i $

Block

To add block math, you must use $$<math>$$. Here are some examples:

$$\begin{equation}
a \times b \times c = 0 \\
j=1 \\
k=2 \\
\end{equation}$$

…becomes…

\[\begin{equation} a \times b \times c = 0 \\ j=1 \\ k=2 \\ \end{equation}\]
$$\begin{align}
i2 \times b \times c =0 \\
j=1 \\
k=2 \\
\end{align}$$

…becomes…

\[\begin{align} i2 \times b \times c =0 \\ j=1 \\ k=2 \\ \end{align}\]

Don’t forget the enclosing $$! Otherwise, your newlines won’t work:

\begin{equation}
i2=0 \\
j=1 \\
k=2 \\
\end{equation}

…becomes…

\begin{equation} i2=0
j=1
k=2
\end{equation}
