### Solutions and latex environment using unnecessary brackets

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 $r is a random variable, but is setting as 1 in this case This is for the external brackets and in this case it is using a point that I didn't put there This is my set up: loadMacros( "PGstandard.pl", "PGML.pl", "AnswerFormatHelp.pl", "parserRadioButtons.pl", "parserPopUp.pl", "contextFraction.pl", ); ############################################################ # Header ############################################################ TEXT(beginproblem());$ShowPartialCorrectAnswers = 1;

###############################################################

# PG Setup

Context("Fraction");

Context("Interval");

Context("Numeric");

Context()->variables->add(n => 'Real');
