Before learning mathematics, we must first learn from the most basic things, because every theory or link of mathematics is based on the previous basic theory and is an interlocking theoretical chain. With this view, you don't have to memorize some theorems, reasoning and other knowledge, so it is naturally easier to learn! You can also do problems at ordinary times, and you can ask the teacher for help in tutor 1 14, which is also very helpful to improve your math scores.
