### Re: Interval context + operator correct answer string

I think that something is not working with the + operator on two intervals, for creating the correct_ans_latex_string that the results table uses.

You are right, the correct_ans_latex_string is to correct. The sum should not actually have correct_ans_latex_string set, but it is inheriting the one from the (0,2] accidentally.

One solution work-around for now would be to use

$range = ($range1 + \$range2)->inherit;


(I know that sounds wrong, but it is the right thing.)

I wil make a fix and submit a pull request.l
