Learn math skills.

1. Grab the class. Science studies focus on daily work, and are not suitable for surprise revision. The most important thing to study on weekdays is 45 minutes in class, and you should concentrate on listening to the lecture and follow the teacher with your thinking.

Assignments are completed with high quality. When writing homework, sometimes the same type of question is practiced repeatedly, so it is necessary to consciously test the speed and accuracy, and be able to think more deeply about such questions when you finish each time.

2. Correct and undone wrong questions: understand each step, and think about why, for the wrong questions, if there are often such situations, then you must: change the calculation methods and habits, such as learning to check and calculate twice to improve accuracy.

The point is to think, and the deeper the thinking, the more thorough the learning, and the more effective it will be with a small number of questions. But this kind of thinking is not based on a vacuum, but on the wrong topic.

1. Comprehensive calculation method:

150x4 5x20=120x20=2400 yuan 2, step-by-step:

Actual purchase of flowers: 150 (4+1)x4=120 pots need money: 120x20=2400 yuan.

3. Unknown number method: X yuan is required.

x÷20=150÷（4+1）x4

x=120x20

x=2400 yuan.

Hello, dear. First method:

30 20 4 = 2400 yuan.

The second type: 150 20 = 3000 yuan.
