I am trying to make a summary template page that shows students their progress and feedback for each of their pages of practice, then a total activity percentage. It works, however I want to be able to just delete the un-needed pages (P1, P2, P3…) and have the denominator be the cardinality of set A. Is there a Desmos function or way to output the cardinality of a set instead of the entire set?
length(A)
should do the trick

Thank you! That worked.
