## You can now use LaTex to write equations :

In the frontmatter of the article add this :

usemathjax: true

After that, simply wrap the math symbols of your article with two double-dollar sign $$: For Example : • use this $$E=mc^2$$ You should be able to see it in your post as: $$E=mc^2$$ use $$mean = \frac{\displaystyle\sum_{i=1}^{n} x_{i}}{n} to write :

$mean = \frac{\displaystyle\sum_{i=1}^{n} x_{i}}{n}$
• Use k_{n+1} = n^2 + k_n^2 - k_{n-1} to write
$k_{n+1} = n^2 + k_n^2 - k_{n-1}$
