But with the growth of age, I am now a senior one. Mathematics is much better than primary school. I have also summed up my experience now.
Do some simple questions first to improve your self-confidence. After you are a little complacent, it is more difficult to make some improvements. Don't flinch when you encounter problems. You must face them bravely, ponder and study them repeatedly. You can ask teachers or classmates some questions you don't understand in the interest class.
In fact, mathematics is always changing. As long as you learn the knowledge in books well first, you will certainly improve in mathematics!
Sister, I wish you an early conquest of mathematics. Come on!
