** Using WeBWorK **

Hi everyone,

I've trying to write some codes for my students, but in the solution I ever get a problem. When I use latex mode and I call some expression it puts an extra bracket. I'd like to remove those brackets. Thanks for any help.

These are some examples:

This appears when I use `(-$r,$r)` and $r is a random variable, but is setting as 1 in this case 

This is for the external brackets and in this case it is using a point that I didn't put there

);
