# Display Math Equation in Post

There will be many posts demostrate how to transfer the mathematical laws to the codes, and the reversed flaw. I start from this famous equation:

Use the steps 1 and 2 indtroducted in Fong Chun Chan’s post, my website is able to show the equation in any post. Because this theme use `kramdown`

as the engine of markdown, I pass the step 4.

Here are the proof the central limitation theorem. Mix of inline and one-line equations.

We have a sequence of independent random variables,

And the mean and variance of them:

Mean

Variance

Assume:

Then:

as

Embedded tex codes in `$$ ... $$`

, the equation was transfered inline or in single line. Thus I pass the step 3 of Fong Chun Chan’s method.

**Note.** Justify the last equation in 2017-04-07 19:31:38
