I would like to accepts intervals as answer (e.g. domain of a function) as in
x<1 and x>-10 and x!=9
x>10 or x<5
But everything I try doesn't work. I can get simple inequalities to check, but anytime I use "and" it renders as $forbiddenkeywordand$, and when I add "and" to the list of allowed words, it doesn't help.
