There is a help page [|here]

However you use double square brackets and the formulas are set up like this

[math] (remember the double square brackets though) \dfrac {3x^3-4x^2+3x-4} {x^4-2x^2+5} [math]

gives math \dfrac {3x^3-4x^2+3x-4} {x^4-2x^2+5} math

[math] area=\pi r^2 [math]

gives math area=\pi r^2 math

[math] \sqrt {\frac {1}{3x} y^5-3} [math]

gives math \sqrt{ \frac {1}{3x} y^5-3} math

[math] \left[ \dfrac {1}{3x} y^5-3 \right] [math]

gives math \left[ \dfrac {1}{3x} y^5-3 \right] math
