You must have the TeX filter turned on (ask the administrator to do this). Then type the following. You must add two dollar signs at the beginning and two at the end.

\left{

X+Y=1\\

X-Y=2

And you will get this:

$$

\left{

X+Y=1\\

X-Y=2

$$

\left{

X+Y=1\\

X-Y=2

And you will get this:

$$

\left{

X+Y=1\\

X-Y=2

$$

Thank you very much,John Isner. I can succeed in inserting it .

can you provide us with codes about common Mathematical symbols ？Because we mathematical teachers use moodle，but we don't known how to insert mathematical symbols into moodle.Thanks a lot again!

The language is called LaTeX. It is a standard language (not invented by Moodle). Do a google search for "LaTeX cheat sheet" and you will find many example of the kind of list you are looking for. I like this one.

Thank you very much Hohn!
