The best way to learn mathematics:

1. Listen carefully in class

2. Do your homework after class. If you don't understand, make a mark and ask the teacher tomorrow. After giving the answer, it will be effective to try again!

3. Buy more exercises to do, especially application problems, practice more, buy people with answers, and remember where you are right and where you are red!

4. If there is no tutorial, it's best to buy a complete solution for primary school textbooks, with the same version in the same grade, because there are many, don't buy it wrong! This book is very good, with exercises and answers. Look at those application problems more, so the score will be 90 or 100!
