I've just spent some time reading some of your other posts and the responses. I'm noticing a pattern where you'll ask a question, someone will try to explain, you'll say you didn't understand it, they'll try to explain again, and then you stop responding.
If someone here is willing to help, don't just stop responding to them. Keep asking clarifying questions. And if you don't understand something, explain the part you didn't understand. Also, when people ask you questions, try and answer them. I've noticed sometimes that people ask you to clarify something and you never respond.
A lot of people here have shown genuine interest in helping you make progress in math. But you need to be willing to put aside your emotions regarding the situation and work with the people trying to help you.
When you don't understand a response, don't just say you didn't understand. Read the response carefully and find the first word or phrase that didn't make sense to you -- even if its the very first word or phrase in the response. The tell the person that you didn't understand that part. And if you can, explain why you didn't understand it.
