The problem you described is not very detailed, so it is difficult to judge. There are problems in math class, depending on whether it is a normal class or a self-study class. Usually in class, in order to complete the progress of teaching tasks, it is generally not answered, especially in high school, many questions can not be explained clearly at once. If it is a self-study class, you can write the topic on paper and let the teacher answer it. Therefore, answering questions in class is generally only aimed at universal problems. It's best to write down your daughter's problems for everyone to analyze. If your daughter always asks questions in class, it is unreasonable to ask for answers. If the teacher is targeted and doesn't answer, he can complain. Sony, your question still depends on your daughter's own learning methods and attitude.
