First the phrasing "teach me math" like it's a thing that is done to the student, or in this case, failed to be done, as opposed to something the student failed to do. An example alternate phrasing may be "help me learn math". I think this is a modern attitude that removes the student agency from the process. If the university failed to give worked solutions and the student feels they need it then there are other sources for worked solutions. I could understand lack of desire to spend additional money on a different textbook with worked examples when so much money was spent on the course in the first place. At the same time I could see reasons for a math course to push students to figuring much more out for themselves to ensure the early principles are deeply embedded into their brain.
