How to use Latex in blogger

For my own record and my fellow math people: we can use Latex in blogger! Toggle the HTML view when editing a post, copy and paste the following codes, and Latex is ready to use!

 

Examples: $\pi$, $\sqrt{\frac{8}{3}}$, $\displaystyle \lim_{x \rightarrow \infty} a^x$

Enjoy!
