Hi, I am using version Moodle 3.8
While creating my multi-part math question using the Stack plugin, I get the error as shown in the attached screenshot. I have created moodle math quizzes before but not multi-part using stack.
I believe this is a Maxima string related issue. Maybe I need to either install Maxima? Or use a maxima syntax input? (for my answer, 25.00)
