An Odd Student Complaint Students often comment: I was doing well in this course until we got to the derived rules. Now I can’t do proofs anymore. WHY STUDENTS HAVE THIS PROBLEM: They have forgotten the 11 basic rules and their strategies and are trying to use the derived rules only.

An Odd Student Complaint Students often comment: I was doing well in this course until we got to the derived rules. Now I can’t find proofs anymore. WHAT TO DO INSTEAD. Make sure that you know and can make use of the basic 11 rules. Use derived rules as a supplement to the 11 rule system. Be conservative.
