How to write mathematical expressions?

[Gamma]

Can anyone tell me how I can write mathematical expressions here. I read the 'LateX crash course'. See what happens.

[tex] a^2 + b = sqrt {c}[\tex]

What am I doing wrong?

You've got a space between [tex] and a^2, methinks that's why it isn't being parsed.

You've got a space between (tex) and a^2, methinks that's why it isn't being parsed.

You're wrong,Nylex.LaTex doesn't mind about spaces.He wrote "a^2 + b = sqrt {c}(\tex)",instead of "a^2 + b =\sqrt{c}(/tex).Which should give:
$$a^2 + b = \sqrt {c}$$

PS.I used "(" instead of "[" so that the compiler wouldn't give error.Click on the fromula to see the code and compare it with yours.

Thank You.

Got it. I think the error is in the back slash in [/tex]

$$a^2 + b = \sqrt{c}$$
