The math plugin has been enabled. You can write math formulas in your posts now. For example, you can write formulas inline, x^2 = 1 or on their own lines:

\int_0^1 x ~ \text{dx} = \frac{1}{2}

or

e=2+\cfrac{1}{1+\cfrac{1}{2+\cfrac{1}{ 1+\cfrac{1}{1+\cfrac{1}{4+\cfrac{1}{1+\cfrac{1}{1+\cfrac{1}{6+\cdots}}}}}}}}
