From the write.as or writefreely blog's Customize page, there is a checkbox for MathJax support.

An example $\int_0^\infty e^{-x^2} dx=\frac{\sqrt{\pi}}{2}$ of an inline equation.

$\Lambda$CDM

$x = {-b \pm \sqrt{b^2-4ac} \over 2a}$

$\cos(θ+φ)=\cos(θ)\cos(φ)−\sin(θ)\sin(φ)$

Block mode is also supported: $$\cos(θ+φ)=\cos(θ)\cos(φ)−\sin(θ)\sin(φ)$$

When $a \ne 0$, there are two solutions to (ax^2 + bx + c = 0) and they are $$x = {-b \pm \sqrt{b^2-4ac} \over 2a}$$
