Never look at a solution until you have spent at least 45 minutes actively trying to solve the problem. Write down the definitions of every term in the prompt. Try small examples (e.g., if the problem is about a general group , see what happens if is the symmetric group S3cap S sub 3 or a cyclic group Zncap Z sub n 2. The "Peek" Method
To transform solution look-ups into genuine mathematical skill, follow this strict four-step workflow:
