Step-by-step feedback (evaluate student input for algebraic equivalence to question, and display)

Students can show the steps that they took to arrive at the answer, and they will have feedback as to whether each step is correct (by determining if it is algebraically equivalent to either the question or the answer).  The previous steps (student inputs or attempts) will be displayed for a student to keep track of.  This is better than having multiple answer fields which might guide the students more than an open-ended question.
