I remember seeing a couple of problems which had a button displayed that would allow the student to repeat a randomized problem with newly generated random numbers put in place. But I have no recollection of which problems they were, and I can't find any by random browsing.
Does anyone have a pointer to such a problem, or have one of your own you could share, or could anyone point me to documentation about this feature?
EDIT: I should mention I did find a small page that does discuss the problemRandomize.pl package
but it then refers to a page that no longer exists:
