I looked at Parenting Stack Exchange and Math Stack Exchange's unanswered page, and one thing that stood out to me is that Parenting SE had only 7 questions, all within the past 2 weeks, but Math SE has nearly 173,000 unanswered questions (at the time of posting).
Do different SE's have different processes internally for marking questions as unanswered?
From what I understand, Parenting SE is a much more tight-knit community with fewer posts per day, but Math SE is much bigger with many more questions asked, and their unanswered questions can be both posted recently or a few years ago.
This might be a bit of a technical question, but thanks for taking the time to read my question. Please also explain in layman's terms, because I am a beginner at programming in general.
