doubt solving

I am looking for an expert in mathematics who can help me with my high school level doubt. It would be preferable if the solution is provided through a written explanation. I am a student of mathematics and struggle to understand the concepts. I am looking for someone who can explain the concepts to me in a clear and concise manner and clarify my doubts. I am uncertain as to the duration and complexity of this project, but if the expert can explain the solutions efficiently it should be relatively quick. The ideal expert for this project should have an in-depth knowledge of mathematics as well as proficiency in written communication. I need a simple and straightforward explanation of the solution that I can understand, so patience and the ability to explain the concepts at a comprehendible and easy-to-follow level are crucial. The expert should be able to make sure that I understand the solution and be available to answer any additional questions I may have.
