I am new to pure mathematics, and I am enthusiastic about it. I posted some questions and answers on math.stackexchange, but received some negative responses.
Sometimes when I was doing my homework or reading the textbook, I came across some difficult problems. I didn't know how to deal with them. I posted the puzzles here, cited the source of the problems, and told them that I have no idea how to deal with it. I am looking for someone to help me, but they said that I am just asking others to do my homework, It's really disrespectful. They left the community rules in the comments, but didn't answer my question, nor did they give me any hints.
Even worse, someone visited my homepage and voted down many of my questions and answers after that. Even if the answer is reasonable, they left no reason. I feel hurt about this. It's unfriendly and I am frustrated. I am still a beginner, and I am unable to post questions about advanced topics. Some problems may be a piece of cake for advanced mathematicians, but they are difficult for me.
I've deleted nearly every posted questions and answers of mine. Maybe I should come back after becoming an advanced mathematics learner? Maybe I won't be blamed for posting those so-called stupid, elementary and worthless questions and answers at that time.
