I've been solving some mathematics quiz/problems for fun. I did answer all the questions I've faced. Considering I don't have the written answers to compare them with mine, is this the right place to post the problem and check if my answer is right?
Note that I don't want to post all the quiz sheet around here, I just had some confusion on one or two questions that I am really unsure that I got the right answer and I would like to check if my reasoning was right and explanation if I was wrong.
I finished school a long time ago and it's been some time since I went through such problems and I totally forgot how to really solve them, so I just went with my instincts, and before I go post questions around here that goes off-topic, I would like your opinion about this.
Is it on-topic to ask such questions around here, and what would be the best tag to use?
