The little thing in that box is a symbol like 3 in the phonetic alphabet, but the pen is horizontal.

Ways to learn mathematics well:

1. Mathematics, like other disciplines, has many conceptual things. The basis of learning mathematics well is to understand what the definition is about.

For example, the meaning of square, cube and absolute value in mathematics. We know that a square is the product of two identical numbers. Of course, a cube is the product of three identical numbers, and the absolute value is a value greater than or equal to 0. Knowing the true meaning of the definition, we took the first step and laid a solid foundation for the following study.

The difference between mathematics and other subjects is that there is no need to memorize, because mathematics does not test questions, but calculates, which is the biggest difference. How to practice specifically.

Many problems in mathematics are based on definitions. As I said before, once you understand the definition, it's easy to start. For example, if you want to merge similar items, you must first define them, that is, similar items. Simply put, it is something that everyone has. If you understand the definition, you will get twice the result with half the effort.

As I said before. Mathematics is not learned by rote, but worked out with a pen. Therefore, for a formula or a definition, only by doing a few more questions about this problem can we use it naturally and truly understand its meaning.

Therefore, for mathematics, we must not be lazy, just look at it without doing it. Only by using more brains and hands can we learn mathematics more flexibly.

Ways to learn science well:

1. If you want to be better than others, you have to pay more than others. Qian Lin, the top scholar, does not advocate staying up late to study. She must ensure enough rest. Efficient study is the most important thing. Concentration in class is the basis of her excellent grades.

Learning means following the teacher closely. He believes that planning is the most important thing in learning, and the finer the better. He will arrange his own study every day. On the eve of the college entrance examination, this plan will even be specific to what time he will do every day.

In the sprint stage, don't delve into difficult problems and digressions, but consolidate the basic methods. Many students belong to the low-minded type and want to get high marks without laying a good foundation. How is that possible? Zhao does not advocate inefficient study such as staying up late. He should pay attention to the combination of work and rest in his study. He always insisted on sleeping for eight hours, and adequate sleep ensured Zhao's efficient study.
