I too had this problem on our moodle site...

My service provider had to recreate a separate site for maths

I am presently using TeXaide which is working well for me and top of all ... you need not worry abt the syntax

try follow these steps

1) download TeXaide from the link

http://www.dessci.com/en/products/texaide/

2) type the expressions as in math type:

suppose you type some thing like this

$$\left( {\frac{{\left( {a + b} \right)\left( {b + c} \right)\left( {c + a} \right)}}{{\left( {a + b + c} \right)^3 }}} \right) \le \frac{8}{{27}}$$

3) copy the expression and paste in a note pad

4) it gives many extra text symbols,

like this

\[

\left( {\frac{{(a + b)(b + c)(c + a)}}{{(a + b + c)^3 }}} \right) \le \frac{8}{{27}}

\]

copy the math text symbols at the end and paste them in the

message box

i.e., you take

\left( {\frac{{\left( {a + b} \right)\left( {b + c} \right)\left( {c + a} \right)}}{{\left( {a + b + c} \right)^3 }}} \right) \le \frac{8}{{27}}

with the symbols $$ at both ends

5) save the changes

6) some part of the object may not look as desired with several

[?] like symbols. With few corrections in the spaces between

characters you can clear those [?] like symbols and can get

the object pasted as desired.

hope I have communicated well
