Task Editing

Hi friends,
I think that we had better used latex for the symbols in a task. It's prettier and more comfortable.
For example, symbol <= can be changed to \le (the syntax is \le), to use latex, start every symbols with

and end it with

.
For latex preview or syntax, you can consult here: http://www.sitmo.com/latex/
What do you think?Any suggestion?
You can see the example for task Mafia http://www.z-trening.com/tasks.php?show_task=5000001096
Thanks for your attention.
