High school entrance examination mathematics | Five major test points for the topic of digital law, example question analysis, the necessary to make major breakthroughs
Finding rules is a type of question type that is required in the high school entrance examination mathematics. Many students are only relatively simple types in the learning of search rules , which is based on textbooks, and these types are also exposed to in primary school, so they take it for granted that finding a question with strength is simpler, but when they enter the review and preparation stage of the high school entrance examination, they find that the problem of finding rules is actually more complicated and difficult in junior high school.
When time is tight, many students choose to give up. In fact, this part of the score can be completely overcome through hard work and different types of understanding. Today, Teacher Tang will give you a detailed explanation and analysis on the issue of finding numbers in the types of rules, hoping to help students in the exam preparation stage.
In the recent years of the examination of mathematical and digital laws of the high school entrance examination, it is mainly divided into five types of test points. As long as these five types master the basic rules in solving problems, it will be much more convenient to find the rules based on this. The skills involved and the itinerary of the problem-solving ideas that are unfolded from numbers are the points that everyone is most concerned about. Below we will classify them for you, hoping to focus on the changes and deformation laws of numbers during the explanation process.
Test point 1 Multiple-sided rules
Junior high school algebra part calculations related to multiplier are the most familiar to everyone. Its characteristic is that the numbers have a large gap in the process of change. At this time, we can consider whether there is a square relationship, and the changes in numbers are related in the order of arranged numbers, so it will be based on this during the consideration process. specifically how to investigate it. We will analyze the following real questions, and you can come from the observation process. Understand the direction of finding its regular rules and how to obtain a breakthrough.

Test point 2 Counting class rules
technical type rules, then the numbers are arranged from large to small or from small to large. The difference between the two numbers Mikarin remains unchanged. The most representative of this type is a series of even numbers and an series of odd numbers based on it. So when we get the numbers to find the rules, we can first check whether the difference between the two numbers before and after is fixed. Then follow this type of method and technique to solve it.

Test point 3 Table class rules
Table finding rules is actually a relatively common type in mathematics learning. The main thing is that the selection of rules based on calendar tables is the most common. This kind of reminds us to expand the changes and sizes of numbers from one of the numbers as the center. For example, in the table of the calendar, there is a difference of 7 and the left and right. Then the center number is regarded as the letter a. The left is a minus one, the right is a+1, the top is a-7, and the bottom is a+7. So when we do not have a problem-solving idea about table rules, we will observe it based on this. Although the rules are different, the ideas are the same, and the methods can also be used to infer in analogy.

test point 4 number array class rules
digital political types to find the rules. We need to start from the two aspects of the arrangement and size of the numbers. In this process, the changes and arrangement of the numbers are the two factors that determine the common decisive factors. Therefore, if you only consider one aspect, you cannot find the final rules. Remember these two principles, then it will be much simpler when finding this type of rules.

Test point 5 New definition of the rule of number
New definition of the law of operation is actually the simplest of these rules, because their rules are given by the question. If you want to find their rules, you need to make simple inferences from the given conditions. This is a test of everyone's observation ability and sensitivity to numbers.

at the end. There are questions about finding the rules of numbers in mathematics in the middle school entrance examination. It is a must-have question type for the middle school entrance examination. So how does the rules come about? There are several common complex laws such as difference relationships, multiple relationships and multiplication. The difficulty of examining each law is determined by everyone's understanding of the laws of this type. Therefore, during the preparation stage, you should understand each type involved and find a breakthrough in the rules. Then, when you encounter similar types, you can find a breakthrough in an efficient way when you find the rules.
