This is a math post.

We can now render inline math x3−5x+2=0x^3 - 5x + 2 = 0 like that.

Also, we can render math in display or block mode like:

∑n=0∞eiπ22nx−n  ∀ x∈(0,1]\sum_{n=0}^\infty \frac{e^{i\pi^2}}{2nx} - n \ \ \forall \ x \in (0,1]

And that summation up there doesn't really mean anything - isn't this cool!

It is rendered using KaTeX\KaTeX!

The math above is rendered with "$" tags like this...

inline math $x^3 - 5x + 2 = 0$

block mode like:

$$
\sum_{n=0}^\infty \frac{e^{i\pi^2}}{2nx} - n \ \ \forall \ x \in (0,1]
$$
