Don't memorize mathematical formulas, but live. If you want to learn math well, you must do more problems. Everything in science is the same. There is no big shortcut. Remember, ask the teacher more. Don't be afraid. Teachers like children who love to ask questions. If you don't ask, the teacher must think you know everything. This is self-deception.
There is also reading more, books are the foundation, and you can learn later if you lay a good foundation. Mathematics is a subject with understanding as the first priority. If the foundation is not good, the problems behind it are not easy to understand.
Finally, review, the best way to review is to read books and do problems! ! Remember, reading and doing problems are inseparable. Finish a question or a group of questions, sum up what you can't do, read the book again, and then do the questions after reading the book until the meeting! ! !
Mathematics is not difficult to learn, it depends on your understanding ability. As soon as you understand, your math scores will come up!
