Hi, I am looking for a topic to do my internal assessment in Mathematics Analysis and Approaches. I thought about doing something related to finances. I thought of studying how someone could enrich by doing bank investments. This is still a broad topic (I think) and I am having trouble creating a research question on this topic. Also, I am not quite sure what approach would be interesting to study this topic. I can talk about growth and financial interest, but I don't know if this is enough. Can anyone please help me?
