# How to write mathematical expressions?

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

$$a^2 + b = sqrt {c}[\tex] What am I doing wrong? regards, Gamma. 2. Dec 21, 2004 ### Nylex You've got a space between $$and a^2, methinks that's why it isn't being parsed. 3. Dec 21, 2004 ### dextercioby 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: [tex] a^2 + b = \sqrt {c}$$ Daniel. PS.I used "(" instead of "[" so that the compiler wouldn't give error.Click on the fromula to see the code and compare it with yours. Last edited: Dec 21, 2004 4. Dec 21, 2004 ### Gamma Thank You. Got it. I think the error is in the back slash in$$

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