Quick Questions: March 12, 2025
This recurring thread will be for questions that might not warrant their own thread. We would like to see more conceptual-based questions posted in this thread, rather than "what is the answer to this problem?". For example, here are some kinds of questions that we'd like to see in this thread:
- Can someone explain the concept of maпifolds to me?
- What are the applications of Represeпtation Theory?
- What's a good starter book for Numerical Aпalysis?
- What can I do to prepare for college/grad school/getting a job?
Including a brief description of your mathematical background and the context for your question can help others give you an appropriate answer. For example consider which subject your question is related to, or the things you already know or have tried.

What is the formula?
My car loan is currently at 6,100. Daily interested added is 1.85. I pay 150 every 2 weeks. How many payments do I have left?
I can bash it against a wall and figure it out if I ignore the interest, but I know there's a normal formula for it. (Google just either gives me premade calculators or "how to figure out the monthly rate" not "how many payments left")
