At Brilliant, you get to share in the problem solving experience with other members. By explaining how you arrived at the answer, you not only help someone else improve their problem solving ability, you also get oodles of glory (along with the additional benefit of improving your communication skills).
Writing a solution can be intimidating, especially if you are uncertain of how to start or what to write (or if you are in a Halloween horror movie). We have provided several guidelines for you to follow to help you craft better solutions over time. You can view the following posts which provide explanations, mnemonics and samples of what not to do:
Level 1 - Apprentice solution writer - Get started!
Level 2 - Journeyman solution writer - Clean up your presentation
Level 3 - Adept solution writer - Identify and connect with your audience
Level 4 - Magus solution writer - Guide your reader
Level 5 - Legendary solution writer - Leave your reader awe-struck
These guidelines can also help you to discuss solutions with other members. If you don't understand a solution which only has equations, ask them: "Can you use words to explain what you mean?". Feel free to ask them: "Can you state the technique that you are using", especially if you are stuck at a step that you don't understand. If they used an approach which you wouldn't have thought of, ask them: "Can you include motivation?" so that you can benefit from their replies.
