Tips to improve the correct rate of mathematical calculation in junior high school

Really understand the method of solving problems, review in class after finishing a topic, retell the idea of solving problems, and copy the wrong book for the wrong topic. After a period of hard work, the problem-solving error rate will be reduced and good study habits will be developed. So we often say that learning mathematics is easy, and the secret is: do what you can do right, and don't make mistakes if you miss it.

First, we should pay enough attention to calculation.

I have always thought that calculation problems are much easier than the analysis of application problems, and I have a solid understanding of some laws and laws, so calculation is a breeze. So I was either overconfident or unable to concentrate when calculating, and the results were full of mistakes.

In fact, it is not easy to calculate correctly. Calculating an elementary arithmetic problem of fractions and decimals requires a lot of knowledge, such as operation sequence, operation rules, four operation rules, etc., after dozens of basic calculations. In this complicated process, a little carelessness will make the calculation of the whole problem wrong. Therefore, the calculation must not be sloppy.

Second: it should be carried out in the general order of calculation.

First of all, make clear the meaning of the question and see if there are any special requirements such as simple method and keeping several decimal places; Secondly, observe the characteristics of the topic and see if there are several simple algorithms for operation; Third, determine the operation sequence. On this basis, relevant rules and laws are adopted for calculation; Finally, carefully check whether there are any mistakes, omissions or miscalculations.

Third, we should form the good habit of careful calculation.

Some students make mistakes because they are not careful in calculus. The data is unclear and the identification is wrong. When drafting, you can't arrange the vertical tables in a certain order, which leads to the adhesion between the top and bottom, the misalignment of the same numbers, which is not convenient for inspection and easy to read the wrong data. Therefore, we must form the good habit of writing numbers vertically.

Fourth, don't blindly pursue speed.

Correct and fast calculation is the ideal goal, but it is necessary to know that correct calculation is the premise and the most basic requirement, and high speed without correct foundation is worthless. Therefore, it is better to calculate slowly, in order to ensure the correctness of calculation and improve the accuracy of calculation.
