What do I do on this app? Or do we just answer questions and ask questions?

So basically you can ask questions about different subjects to the community and if someone knows the answer they'll respond. When you ask a question you give away points to the person that helped you, you can thank them, rate them, ask further in the comments, and even mark someone as Brainliest which will note their answer as the best answer for others who need to ask the same question. You can also answer other people's questions you know the answer to and earn points!!
