? In our primary school study, mathematics is often a headache. In the process of learning mathematics, we should learn to summarize and review, which will give us a clear understanding of what we have learned and a reasonable analysis of the total knowledge points. The following summarizes some problems of primary school mathematics.

? The first kind of questions are questions. The problem of normalization is to calculate the single quantity or value of an object by multiplication and division, and then calculate the total quantity or total price required in the topic. The second type of question, sum and difference, is solved by addition, subtraction, multiplication and division. In the calculation process, we should pay attention to the operation order of addition, subtraction, multiplication and division. The third type of question, the occasional question. This kind of problem generally describes the sum of the moving distance or moving time of two objects, and achieves the purpose of calculation through multiplication, division and addition. The fourth question type, age question type. This category is to find out someone's age by adding, subtracting, multiplying and dividing.

? The fifth type of question, the train question, allows you to solve problems with speed and time. The main purpose of this kind of question is to analyze the question clearly and clarify the thinking, so as to answer the question correctly. The sixth kind of problems, navigation problems, should make clear the relationship between ship speed and water speed, distinguish between sailing with the water and sailing against the water, and know how to calculate. The seventh problem, the problem of chickens and rabbits in the same cage, is the most classic elementary school calculation, as long as you practice more. The eighth question, the profit of goods, is to understand the meaning of cost, profit, selling price and unit price, have a clear idea of the topic, and list the ideas, which will make it easier to write a lot. The ninth problem, the problem of deposit profit, needs to understand the concepts of interest, principal and interest rate, which is similar to the problem of commodity profit. Clear thinking, the topic is easy to understand.

? There are still a lot of elementary school mathematics knowledge points for primary school students. To sum up, the above are some of the problems summarized.
