i am a real ignorant in latex so i need all the technical information.i already have the simbols but can't practice because the technical issue.

Are you enclosing your code with the TEX tags?

without tags: \sqrt{\frac{x}{y}}

with tags: $$\displaystyle \sqrt{\frac{x}{y}}$$

\sqrt{\frac{x}{y}}
it does not convert to mathematical symbols
sorry for the deep ignorance.

If you click the "reply with quote" or the "go advanced" you should see a $$\displaystyle \Sigma$$ on the toolbar. Click that tab. You will see [noparse][/noparse] appear. Type the Latex code between them. Or else, highlight the code and then click the $$\displaystyle \Sigma$$

So [noparse]$$\displaystyle \sqrt{\frac{x}{y}}$$[/noparse] gives $$\displaystyle \sqrt{\frac{x}{y}}$$

$$\displaystyle \frac{2+sqrt{x^2+3}}{3x+2}-{x-2}$$

Thank's a lot.
