I don't even know where to start. How do I start typing text and equations. Where do I select the math symbols from. Lets say I want to start typing an equation now. What do I do? Thanks

It is just a matter of learning the codes.
Here are some examples:
$$\cup$$ gives $\cup$ is union
$$\cap$$ gives $\cap$ is intersection
$$\subseteq$$ gives $\subseteq$ is subset
$$\cup$$ gives $\cup$ is union
$$\in$$ gives $\in$ is element
$$\emptyset$$ gives $\emptyset$ is emptyset
$$\wedge$$ gives $\wedge$ is or
$$\vee$$ gives $\vee$ is and
$$\sqrt{x+1}$$ gives $\sqrt{x+1}$

Thanks plato.

I can't see learning the code. I have to select from icons. Finally able to piece it together.

Create the formula on the Latex site (google "latex") then copy and paste using TEX icon above reply window (self-explanatory)

Went to your recommended link "Latex Tutorial" but couldn't find a latex tutorial.

EDIT OK found the Latex tutorial (.gif). Seems cumbersome. I prefer selecting from icons ala MS Word Eq Editor or Latex site. Could the whole post be done in MS Word using Equation Editor and copy paste the whole thing? Easiest way to find out is to try, which I will do but have to go now.

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

OK That seemed to work niceley. I found the following Eq Editor very easy to use:
www.codecogs.com/latex/eqneditor.php

In the editing window of above site pick the symbol, fill in blank, and Latex code is automatically generated, and beneath editing window the actual equation is displayed. Then copy code (ctl-c) and go to Math Help Forum and post reply or start new thread. Select TEX icon and then paste the code in between.

EDIT: Whoops! Not home yet. The above site lets you create AN eauation. But ultimateley you want to put the equation in with texr. You can first paste all your eqs in the post and then intersperse text. It's not practical to jump back and forth between Math Help Forum and your Post for every equation. Hmmmmmm.

Latex Equations with Text
\overline{S}= S\cup {S}'\;\; \; \; \beta (S)=\overline {S} \cap\overline{S^{\sim }}\; \; \: \beta (S)= \overline{S}-S^{0}\; \; (S^{0})^{\sim} = \overline{(S^{\sim })}\; \;

1) $\overline{S}= S\cup {S}'\;$

2) $\beta (S)=\overline {S} \cap\overline{S^{\sim }}$

3) $\beta (S)= \overline{S}-S^{0}\;$

4) $(S^{0})^{\sim} = \overline{(S^{\sim })}$

OK. Crude and cumbersome but seems to work

a) write all eqs on above text editor and add spaces between eqs with the text editor.
b) copy and paste all of the code into your post.
c) segregate the individual equations by copying them individually using "TEX" icon

I will use the above eqs in a question I have which I will post.

PS I welcome any suggestions on a better way to combine Latex with Text.
(Strange, just noticed I can't add extra spaces between text)

e^(i*pi)
$$a\ b$$
$$a\ \ b$$
$$a\ \ \ b$$

give

$a\ b$
$a\ \ b$
$a\ \ \ b$
